Shop Local

The Importance of Shopping Local and Supporting Small Businesses

Often the reason business owners decide to branch out on their own is because they feel as though they can offer a better service or product than what is currently available, because of this there are so many benefits to shopping local and supporting small businesses.

We’ll delve deeper into a couple of those benefits and also talk about the different ways you can show your support.

 

 

A Better Shopping Experience

In today’s fast-paced world, online shopping is the preferred method of shopping. It’s quick, it’s easy and it’s cheaper however it completely eliminates human interaction. When you shop in store, you’re getting the desired product and/or service as well as an experience. The character of the business will often reflect the owner’s personality and by choosing to visit the store, you’re not only giving yourself the opportunity to get to know the person behind the service and/or product but you’re also giving them the opportunity to get to know you. Often, you’ll find employees will happily take the time to listen to your needs and find you the best solution because they care (and not just about your money) which is difficult to say about larger corporations with monthly sales targets determined by an interstate head office.

 

Strengthen the Local Economy

When you shop local, it comes back to full circle. Let’s break that down, shall we? By spending money, you’re creating demand. By creating a demand, there is an increased need for jobs. With an increased need for jobs, there are lower unemployment rates and lower unemployment rates lead to more people having a disposable income. That disposable income will (hopefully) be spent locally which then creates more demand and starts the cycle all over again.

It’s simple, when you shop local – you’re investing in your community.

 

So, how can you support local and small businesses?

Spend money, of course – particularly important during the holiday season! However, if you are unable to do so here are a couple of other ways to show your support for free.

  1. Raise Awareness
    Talk to your friends and family, share a Facebook or Instagram page or leave a positive review for others to see.
  2. Educate Yourself
    Research the local businesses in your area and make some time to go see what they have to offer.

 

 

Unfortunately, owning a business is tough these days. Online shopping and large franchises pose bigger and bigger issues to business owner’s every day.  So remember that when you support a local or small business – you’re supporting local people, local jobs and someone’s dream.

Static Shock vs Electric Shock

What is the difference between Static Shock and Electric Shock?

Over the past hundred years, electricity has evolved and adapted into a necessity which society cannot live without. We have become quite dependent on its uses; making it hard to escape, from flicking the kettle on in the morning to the powerful yet beautiful strikes of lightning during a storm.

Put simply, electricity is made through the burning of fuel. Australia uses either coal or a natural gas, which is burnt to heat water and create steam. This turns a turbine generating electricity, then travelling along the conductor wires, which we call powerlines, to the specified destination.

Although electricity is used every day, it can sometimes be harmful but also fun – being the core ‘ingredient’ to some experiments.

Static Shock

Static electricity, also known as electrical energy at rest, is the build-up of electric charge on a material. This charge is usually built up through friction, which is the contact between two objects which are both insulators.

One of the most common science tricks to create static shock is to rub a balloon against your hair, making your hair stand up on its ends.

Another example is to rub your rubber-soled shoes against the carpet and then touching a metal door knob, giving you a ZAP!

These things happen due to an imbalance in electrons in both objects, with one losing their electrons, creating a positive charge and the other gaining electrons, creating a negative charge.

A static shock isn’t harmful; it may be uncomfortable and cause a bit of a fright to the receiving personnel.

Electric Shock

An electric shock is the sudden discharge of an electrical current from an electrical source, like a power point, which has enough force to pass through a human body part. This electrical energy flows through the human body part, creating a shock type feeling which can cause little to no injury or can be life threatening.

There are some different ways which you can experience an electrical shock, including; faulty appliances, power points, damaged electrical cords, electrical appliances and water coming into contact, incorrect household electrical wiring, and also a lightning strike.

Electrical shock can have little external evidence that it has occurred, however the internal effects of receiving an electrical shock could be life threatening.

An electrical shock can cause burns, tingling, numbness, nerve damage, and even cardiovascular problems. Seeking advice from a health care professional is always advised after receiving an electrical shock, even if you feel ok.

The main difference between these two different but similar shocks, are the outcomes and the way which they are created.

Static shock is created through human effort and electrical shock is created through electrical means.

Static shock doesn’t give a harmful result and electrical shock can cause no to life threatening results.

The Effects of Natural Lighting vs Artificial Lighting

The Effects of Natural Lighting vs Artificial Lighting

Light is emitted via two different sources – natural and artificial. The sun is the primary source of natural light, while light globes are the primary source of artificial light. There has long been an awareness about the effects that lighting has on the human body, and now science is alerting us to the vast impact that light has on our physiological, psychological and emotional wellbeing.

So `when choosing how to light your home or office, a lot of consideration needs to be put into it. To stay healthy, alert and productive, people need to have regular circadian rhythms and keep to a constant sleep/wake cycle as directed by our exposure to certain light wavelengths during the day.

How does light affect us?

There are two key hormones that are affected by light – the sleep hormone melatonin and the stress hormone cortisol. When waking up in the morning, it’s important that our bodies produce enough cortisol to promote alertness. Into the evening and towards sleep, people need to stop the production of cortisol and begin producing melatonin.

To do this, the body needs access to bright light with blue wavelengths in the first few hours of waking up. Brightness and intensity may be decreased throughout the day and by night, blue light must be eliminated and amber tones, increased. By the time we head towards sleep, we should eliminate light altogether.

Human’s have evolved to use the sun’s light to dictate their sleep/wake cycle, so correct lighting design for daily living and health is about mimicking sunlight. This means that careful attention must be paid to colour temperature and light intensity.

In fact, our reliance on light is so intense that during the darker months of winter, many people can experience Seasonal Affective Disorder. As the mornings are much darker during the colder months, we do not experience as much intense blue-rich light in the mornings, affecting our cortisone levels. This can make us feel less alert and less vibrant, which can sometimes evolve into a depressive state.

There is some concern that the excessive use of smartphones and tablets in the late evenings can affect sleep quality because they emit substaintial amounts of blue/green light at the wavelengths that inhibit the release of melatonin, preventing us from becoming drowsy. Poor quality sleep has been linked with increased risk of obesity, diabetes and heart disease.

Natural Light

Natural light is full spectrum, meaning that it contains all colours of the rainbow, as well as colours (wavelengths) that we cannot see, such as infrared and ultraviolet. Without all of these colours, our world around us would look a lot more dull, as we wouldnt be able to see skintones or textures, for example, in their full glory.

Natural light is also dynamic, meaning that the intensity and colours of light change with the time of the day, time of the year, weather and location.

Our mood, energy, metabolism, sleep and recovery all depends upon the daily cycles of natural light, since these changes synchronise our circadian rhythm and hormone cycles. When the sun is overhead, daylight is bright and rich in blue (which stimulates us), while at sunset, daylight softens and is dominated by red (which relaxes us). These changes are due to atmospheric filtering of sunlight, which changes with the angle of the sun. Humans, plants and animals depend on these daily and seasonal cycles of natural light for their health and wellness.

The benefits of natural light are extensive:

  • Day-light increases our productivity and comfort.
  • Access to natural light improves one’s circadian rhythms.
  • Working in daylight boosts mood and motivation leading to the work is done faster, creating more pleasure and essentially better results.
  • It creates a calmer indoor environment, reducing one’s stress.
  • Utilising natural light reduces reliance on electricity and therefore reducing electricity bills.
  • Studying in natural daylight reduces stress and has been shown to improve student performance.

Artificial Light

Artificial light is used as the substitute when there is an insufficient amount of natural light, with a similar concept as natural light. Artificial light is composed of visible and invisible radiations like ultraviolet (UV) and infrared (IR).

Artificial light can come in a variety of different colours and intensities, depending on the environments mood.

The UV and IR radiations which artificial light sources hold aren’t harmful to the health of humans, as long as they aren’t situated at a close range or extremely intense. Think of it like this – the annual dose of UV from artificial light is equal to a one-week holiday in an overly sunny destination like the Sunshine Coast.

Although artificial light isn’t harmful most of the time, it has some aspects which can essentially create some health risks.

The blue light aspect of artificial light can have a deeming effect on one’s internal body clock, along with the hormonal system which can lead to overall health problems relating to sleep deprivation and stress. The body’s internal body clock runs on dark and light, and the different chemicals in the brain to let us know ‘when its time to get up and when its time to go to sleep’. These chemicals are then affected by the artificial light which is being used. The blue light in smart phones is the perfect example; when used in a dark room before sleeping, the production of melatonin is reduced, making us less sleepy and more likely to stay awake. If this is a reoccurring situation – sleep deprivation can quickly become a major health problem.

UV light is also a harmful ingredient in both sunlight and artificial light with excessive exposure. UV is what creates the tan on the outermost layer of the skin, but skin cancer can become a quick health problem if too many skin cells become harmed in the process. With tanning beds are a popular way to create this tan, the large amount of UV light which is used can have a major effect on one’s skin and even create eye damage.

Ducted vs Split

What To Choose? Ducted Air Conditioners vs Split Air Conditioner 

So, you’re after an air conditioner but are stuck on which type to purchase – a ducted reverse cycle system or a high wall split system?

Both are effective at cooling a space, but the way that they do this differs dramatically. Your choice will often depend on a number of factors such as the space that you are wanting to cool, your budget, whether your home can accommodate the system, and much more.

Split-or-Ducted-Air-Coditioner-Panasonic

Ducted Air Conditioning

Ducted reverse cycle air conditioners work just as the name suggests – through a series of ducts. These are hidden within the roof space and out of sight, making it the more attractive choice. They contain a central unit, known as the fan-coil unit. Ducts then branch off of this fan-coil unit and run to different rooms/zones within your home. The air is expelled from the vents in your ceiling, which are the only visible parts of the system.

GREEN EFFICIENT LIVING CAN PROVIDE YOU WITH A NUMBER OF DUCTED REVERSE CYCLE AIR CONDITIONING OPTIONS THAT SUIT YOUR LIFESTYLE AND REDUCE ENERGY WASTAGE

There are many pros for ducted air conditioning in comparison to split systems, with one of the biggest being that you can easily and efficiently heat or cool your whole home at the touch of a button. Controlled by a thermostat, ducted systems are much better at keeping a consistent temperature throughout your whole home, but the option to have your system zoned means that you can individually control the amount of conditioned air to each room. There are two ways that you can do this; with a simple on/off switch, or a variable air volume controller which you can increase or decrease the amount of airflow to suit your requirements. The last option also allows for better air balancing throughout your system. The entire system is completely hidden within the roof cavity of your home (besides the vents in your ceilings), making it the more attractive option over split systems. Ducted systems are often a lot quieter than their counterparts, with the only noise being a quiet fan noise from the outdoor unit, and gentle passing of air through the central filtration grille.

Despite the extensive list of pros, ducted air conditioning systems also have their limitations. Ducted systems are the more expensive option to purchase and have installed. As the system is installed within your roof, technicians will need to spend a large amount of time and effort, cutting into your ceiling and this can often add to the cost. Having a ducted system installed is best done during the building or renovation of your home (but not limited to), and they can often be restricted to which homes they can be installed in. Apartments and dwellings with limited roof space often may not be able to have ducted systems installed due to this reason, and already built two-storey homes need a large amount of extra consideration and planning. They are also not the best option if you only spend an extensive amount of time in only a small area of your home.

Split System Air Conditioning

Split system air conditioners are the most ideal solution for single room heating and cooling. They are made up of two components – an indoor unit (head unit) and an outdoor unit (compressor). The indoor unit moves the cool air around the room, while the outdoor unit dissipates the heat from the cooled area (heat exchange).

Panasonic High Wall Split installed in a wall

Split system air conditioners are the more cost-effective choice to purchase and have installed. Due to the fact that you are not purchasing an entire system of ductwork and vents, the costs can be minimal in comparison to ducted systems. A considerably less amount of time is needed for technicians to install them, and there is minimal modification required to your home. If budget is a restraining factor, more split systems can be added to your home if you require later on, or as your budget allows. Due to the fact that split systems only heat or cool one room or space of your home, they have lower energy demands and therefore are quite cost-effective to run.

However, there are also cons involved with having a split system installed within your home. The heating or cooling capacity is limited with splits, and therefore may not be a possible option for your space. While they are the cheaper option singularly, if you need multiple units within your home, the costs can add up. The bulkiness of both the indoor unit and the outdoor unit, and the inability to hide them can often become an eyesore and stand out on your wall. So if you are looking for a neat and tidy option that is easily concealed, then a split system is not your choice.

So which option is best for me?

Each of these systems essentially performs the same job, but personal preferences and limitations can restrict which one is best for you. It is important to take into account each of the pros and cons provided so that your system benefits you for years to come.

Factors to think of when deciding include:

  • What maintenance/upkeep is included – A ducted system will require yearly services by a professional, while a split system will require more regular cleaning that can be completed by the homeowner, and professional servicing less frequently.
  • How much you want to spend – A ducted system will cost more to purchase and have installed upfront but the options to zone your system means that their running costs can be reduced. While a singular split system will cost less upfront, should you need to add more in the future, the costs can add up.
  • What area you are looking to cool – Do you want to cool your entire home or just one room? Should you only need one room cooled, is important to think about whether you will be wanting to cool more in the future.
  • Aesthetics – The way the system will look is also something to think about. While split systems stand-out on both an indoor and outdoor wall, they are becoming much more visually appealing.

Solar FAQs

Frequently Asked Solar Questions

Over the years we’ve become accustomed to hearing the same questions relating to having a solar photovoltaic (PV) system installed. So, as we are dedicated to education and helping our customers as much as we can, we have compiled a list of our most frequently asked questions to help you on your journey.

1. What is a grid-connected solar system?

A home without a solar system draws its energy from the electricity grid. A grid-connected solar system is a solar PV system that is connected to the electricity grid. Your household will consume the energy that is created from your solar system first, and if more is needed, it will draw the remaining electricity from the grid. It also allows your system to send power back out to the grid. If your household is not consuming the entire amount of energy that your system is creating, then that surplus is sent back out to the electricity grid. This surplus is measured and credited back onto your power bill. Depending on what state you live in and what electricity supplier you are with, this value will vary.

2. How much will my solar system cost me?

As an extremely broad question, the answer is dependent on a number of factors. The final price depends on what brand of system you choose, how many panels you have installed, whether you decide on a string inverter or microinverter and much more.

ALWAYS get multiple quotes to compare prices and remember that the most expensive quote doesn’t necessarily mean equate to the best system. In South Australia, on average a 5kW (kilowatt) system costs approximately $5,500 but there are some elements that will affect this price.

3. What size system do I need?

To answer this question, your system designer will need to understand your energy habits such as your daily usage amount, your energy usage patterns, your location, etc. From here, they will be able to offer you the correct sized system. While your installer should be able to offer you a rough estimate just by receiving your latest electricity bill, they should not be able to present you with an ACCURATE system size without first asking these questions.

4. How many solar panels will I need?

Once your installer determines the system size that your household requires, they will then look at what panels will best suit your system. Not all panels are created the same, or yield the same amount. So your installer should be working out which panels are most appropriate for your lifestyle and energy patterns. They will also need to look at elements such as your roof size and budget.

5. Will anything else affect the price of my system?

There are a few added elements that will affect the overall price of your system. Each solar PV system is tailored individually, so don’t assume that just because your family member has a 5kW system with X amount of panels on their home, means that you will pay the same price for the same system. Factors need to be taken into account such as additional labour costs for things like a double storey roof, panel mounting brackets to angle your panels correctly if your roof is flat and much more.

6. How much money will I save with my solar system?

Typically, it can take anywhere from four to six years for a system to pay itself off in South Australia. Payback times depend on a number of things such as your location, your energy consumption, daily usage patterns, how well you maintain your system, the size of your system and your feed-in tariff.

Ensuring that you have the correct sized system will speed up your payback times. Having a system that is large enough is important as it will not only cover your power consumption, but it will maximise your return on investment. But having a system that is too large will mean that you’re exporting a large surplus of energy back into the grid and as feed-in tariffs are no longer as high, you will be selling your power for less than your electricity rates. So it’s important to ensure that your system is correctly sized to maximise your return.

7. Is my roof right for solar?

Not every roof is suitable to have a solar system installed on it. Generally, there are six key factors that will determine the suitability of your system.

  • Orientation: While a north-facing roof is best for optimum production in South Australia, it has been proven that panels facing north.
  • Shade: Solar panels only produce maximum energy in full sunlight. If a part of a panel becomes
    Image showing partial shading of solar panels
    Shadows on solar panels can affect the generation values of the entire system.

    shaded, then the output level is reduced. It is therefore necessary that your roof does not experience any shade if possible. Vegetation and overgrown trees can easily be removed, but shade from chimneys or poles on the roof is much more difficult to work around. If there are certain ares of you roof that do experience shading during the day, then your installer may offer you a system with microinverters to avoid your output dropping too much.

  • Size: Your roof has to be large enough to have the space for the number of panels that you require. The minimum sized system that can be installed in Australia is a 1.5kW, which generally equates to 6 solar panels. If your roof is not large enough for 6 solar panels, then you may need to look at other options.
  • Age: The age of your roof will be an indication of its structural integrity. If you are in an older home and are unsure about whether your roof will be able to safely support a solar system then it is best to have an inspection done beforehand.
  • Pitch: Solar panels
    Solar panels installed on a roof with a very steep pitch
    The pitch of your solar panels can greatly affect their power generation values.

    generate maximum power when they are positioned perpendicular to the sun. Your installer will need to take the pitch of your roof into account when installing your panels at the optimal angle. If the pitch of your roof is too flat or too steep, then your installer will need to use mounting brackets to angle the panels correctly for maximum yield.

  • Material: While solar panels can generally be installed on any roof, there are some exceptions. Metal roofs are often the best to install a system on, while tile roofs can be quite fragile and generate an extra cost.

8. Does the temperature during the day affect production results? Does hotter weather equal greater energy production?

Many people believe that hotter weather produces more energy, however, it is much the opposite. The hotter the day, the less energy that your system will produce. This is because a solar system converts LIGHT into energy and not HEAT.

A solar panel has an optimal temperate range that is best for producing the greatest amount of energy. As the temperature rises out of this optimal range, the production efficiency begins to decrease. Excessive heat is therefore detrimental for a solar panel’s production. Instead, the days that you will find you produce the most energy are on sunny, cooler days.

9. Is there any maintenance involved in having a solar system on my roof?

Despite the rumours, solar panels are NOT self-cleaning. So, like any other appliance or installation around the home or office, we do ask that you occasionally inspect and perform a small amount of maintenance on it. You can find a copy of our maintenance manual here.

10. Do I need developmental approval to have a solar system installed?

Generally speaking, you shouldn’t need to get council or planning approval when having a solar system installed, however, there are a few instances in which you may. If you live in a council strata development, then getting approval from the body corporate may be required, or if you live in a heritage listed home then you will need to get council approval. If you are unsure whether or not you should be receiving approval, you can ask your solar installer or local council for guidance.

11. Will I still be using energy from the grid?

Yes. Your solar system only generates energy when there is sunlight, and when this energy is generated it needs to be used immediately. At night time when there is no energy being produced, your system will draw energy from the electricity grid so that you can continue to use the appliances within your home. Should you have a battery system however, it can store energy produced by your system to use when your system is not generating power.

Still unsure?

Solar systems are all individually tailored to ensure maximum power generation for your household. If you have any further questions, please do not hestitate to give us a call on (08) 8297 3422 today, to speak to one of our qualified installers.

The Most Common Electrical Issues Around The Home

The Most Common Electrical Issues Around The Home

Electricity should be seen as a tool and the ways that we can use it are endless. But we can’t forget just how dangerous it can be when installed incorrectly, not properly maintained or used without care. Issues such as flickering light, tripping circuit breakers, electric shocks and much more, all indicate possible points of concern with your home’s electrical circuit. If you are experiencing any of the following issues, please call us today to have them inspected to ensure your’s and your family’s safety.

1. Tripping Circuit Breakers

Many people are unsure about the difference between safety switches and circuit breakers within their home. Circuit breakers provide protection for your WIRING and ELECTRICALS within your home by opening the circuit when a fault is detected. They do not provide personal protection from electric shock. There are three main reasons why your circuit breaker might trip within your home.

One of the most common reasons is that you are ‘overloading your circuit’. This is an electric circuit that is carrying more current than what it can handle, running the risk of causing a fire or an injury through overheating. For example, in one outlet you may have a powerboard plugged in, that is overloaded with cords and adaptors that, simultaneously, are drawing too much current. Your outlet/powerboard may not be able to handle such a large current and therefore runs the risk of overheating. Your circuit breaker would trip to avoid any overheating, minimising your chances of getting hurt.

Your circuit breaker may also trip due to a ‘short circuit’. In your homes electrical circuit, this occurs when a live wire touches a neutral wire, resulting in high current and therefore triggering your circuit breaker. There are many reasons why these two wires can come into contact with one another. Your attachments in your home may be extremely old and deteriorated, possibly have been chewed through by an animal or pest causing them to become loose, or caused by a faulty appliance.

Ground faults are another reason why your circuit breaker may be tripped. A ground fault is when electricity finds an unplanned path to ground and are often caused by damaged wiring or faulty/old appliances. They often occur in ‘wet’ areas of the house such as the kitchen or the bathroom.

Sometimes faulty circuit breakers can be installed unknowingly. These circuit breakers can trip at lower current ratings than what are specified. If this were the case, your circuit breaker might be tripping quite frequently and need replacing immediately.

If your circuit breaker trips, identify why it may have happened and eliminate the chances of it happening again. If you cannot find the cause, or it electrically more advanced than simply unplugging a device, call an electrician today.

2. Frequent Power Surges

Power surges in the home can be caused by a number of reasons, most of them within your control. They occur when there is an interruption to the normal flow of electricity within the home, or when there is a sudden influx of electricity into the system.

Internal power surges  are most common, and may include:

  • Power hungry devices such as refrigerators and air conditioners being switched on.
  • Faulty wiring.

External influences include:

  • Animals chewing through wiring
  • Fallen tree limbs touching power lines.
  • Lightning strikes

While the actual surge of electricity is generally extremely quick, the damage that it can have on your appliances can last a lot longer. Frequent power surges can damage your electrical devices componentry and reduce their life expectancy.

To protect yourself from power surges in the home, you need surge protectors installed. There are three different types of surge protectors you can choose from:

  1. Portable surge protectors: These plug into an outlet and protect the device that is plugged into them. While cheaper than other options, these run the risk of only being able to be used once.Screen Shot 2019-02-13 at 1.27.09 pmScreen Shot 2019-02-13 at 1.38.49 pm
  2. Powerpoint surge protectors: These surge protectors are installed within the powerpoint itself, and therefore must be fitted by a qualified electrician. They protect anything that is plugged into that powerpoint. 2025SFWE
  3. Main switchboard: Installed by a licenced electrician at your switchboard, these surge protection devices (SPDs) protect your entire circuit from a power surge. Should a fault occur, they switch off the power to your entire home keeping you and your family safe. PO_OvervoltageProtection_PIS_1

It’s important to remember that these are all different types of surge arrestors, and are used for different types of surges and in most cases, two types will be safest for your property. The primary type is used for large surges such as lightning strikes, to protect your motors or non-sensitive equipment. The secondary type can be utilised to protect your electronics.

3. Buzzing/Humming Outlets and Switches

A number of issues in the home can cause outlets and switches to buzz – some are normal and some may be an indication that there is something else going on. Generally, there is no need to worry, but if you are concerned, then call us today to complete an electrical inspection.

Dimmer switches work by ‘chopping up’ the current between the switch and the light, so rather than actually dimming the light itself, it flickers rapidly enough so that it appears dim. It is this ‘chopping up’ of the current that can produce vibration and therefore cause a buzzing noise. High-quality dimmer switches should have a filter to reduce this buzz, but if the noise intensifies it may be another issue. It may be a sign that you have an LED or CFL globe installed that is being controlled by a dimmer built for an incandescent globe. Your globes may also flicker if this was the issue. It could also be a sign of an overloaded switch. Dimmer switches are rated according to the maximum wattage that they can handle. If you have a globe in your fixture that’s wattage is higher than what the switch can control, then you may hear some buzzing and need to upgrade your switch.

If an outlet in your home is buzzing, then it may be a sign of an overload or bad wiring. The wires in your home may have become loose, which can cause them to hum. This is more prevalent in older homes with outdated, old, or worn out wires, but there may also be a chance that they have been installed incorrectly. To see whether it is the outlet itself, or possibly an overload, try plugging in a different appliance to see if the outlets continue to buzz. Only do this if it is safe to do so, but if you are in doubt, please do not touch it. Instead, call us today to organise an inspection. Any loose wires or connections within the home shouldn’t be ignored, as larger, more serious issues can result.

4. Electric Shocks

An electric shock occurs when a person comes into contact with an electrical energy source. This electrical energy then flows through the person’s body and causes a shock. Exposure to an electric shock can cause anywhere from no injury at all, if you’re lucky, to serious health issues and even death. It’s important to distinguish between whether you have experienced an electric shock, or simply a static shock.

Static shocks are simply the build up of a negative electric charge on the surface of an object. Negative charges are carried by paricles called electrons, which are found in all matter. Most electrons are packed within matter, but sometimes they can sit on the surface. If two objects come into contact with one another, the electrons on the surface will move to the material with the greatest bonding strength or pull (such as your body). This movement of electrons is the ‘zap’ that you experience, which is completely harmless.

Static shocks are nothing more than annoying, but electric shocks are a much larger cause for concern. Depending on the duration and intensity of the shock, you may experience:

  • Tingling.
  • Burns to the skin or internal tissues.
  • Loss of consciousness.
  • Loss of breath.
  • Interruption to the natural rhythm of the heartbeat, causing it to beat out of rhythm or not at all.

There are many situations within your home where you could experience an electrical shock. These include:

  • Faulty appliances.
  • Damaged or frayed electrical cords and wiring.
  • Electrical appliances coming into contact with water.
  • Incorrect or deteriorated household wiring.
  • Downed powerlines or lighting strikes.

If you are certain that you are experiencing electrical shocks within your home, do not hesitate any longer. Call us today to organise a site inspection before it worsens. Electricity is extremely useful within the home, but it can also be extremely dangerous.

5. Higher Than Average Electrical Bills

If you have noticed that your electrical bills have been higher than average, there may be a few reasons why. Certain things that can cause higher electrical bills include:

  • Keeping appliances plugged in and turned on when not in use.
  • Increased electricity rates.
  • Leaks in your hot water system.
  • New appliances, such a larger televisions, can use a lot more power, so be sure to purchase appliances that are ‘energy smart’.

Higher electricity bills may also be the result of old appliances or wiring within the home. Older appliances can degrade and lose their efficiency over time causing them to become large consumers of electricity. It’s important to maintain your appliances and update them when necessary to avoid paying too much for electricity. Faulty or degrading wiring can also consume larger amounts of power as it deteriorates, just to provide appliances with the necessary amount of power. It’s important to distinguish what may be causing this spike is power usage so that you can amend it. If you are unsure, call an electrician today.

Why Should You Get An Electrical Inspection?

Electricity in the home can be a marvelous tool. It can be a source of light, heat, entertainment and much more! But when it is neglected, it can become more dangerous than helpful. Have a think back to the last time that you had your home or business’s electrical system checked to make sure that everything is working safely and is compliant with the latest regulations and standards. Have you EVER had an electrical inspection carried out? Is your home old or recently built? Or maybe you are in the process of purchasing. It may be time to have an inspection done to keep you and your family safe.

According to Master Electricians Australia, 15 people on average are killed in Australia each year from electrical-related deaths inside of their homes and 300 people on average, are hospitalised. The Electrical Regulatory Authorities Council also states that between 2016 and 2017 90% of the people who were fatally electrocuted in their homes were members of the general public (i.e. non-professionals).

Many electrical issues in the home go undetected to the untrained eye. This is why it is extremely important to have your home’s electrical safety inspected to ensure that you and your family can live your days free of risk.

What Happens During An Electrical Inspection?

During an inspection, the electrician will visually inspect your home or business’s electrical system ensuring that all wiring, system, and components meet the relevant legal standards.

Some elements of the inspection will be simply a basic visual audit with recommendations regarding non-compliant components. Others will be an in-depth audit ensuring continuity of electrical system and safety switches are tested, the polarity of the outlets. Unfortunately, as most of the electrical system is inaccessible in wall cavities, a thorough visual inspection with a testing of the electrical system is the extent that can be carried out without perforating the wall.

It is important to ensure that the person that is completing the electrical inspection on your home or business is qualified to do so. By ensuring this, you will have peace of mind knowing that they are aware of and trained on the issues to be aware of and recommend how to fix the problems should they find anything.

When Should You Get An Electrical Inspection?

Despite the importance of electrical inspections, they do not need to be carried out annually. Typically, every three to five years should suffice. Technology is constantly changing and as a result, so are the electrical standards and regulations of compliance. However, there are three major situations in which you should have an electrical inspection completed immediately.

1. If you have an older home.

As mentioned, electrical standards and technology are constantly developing and changing, and therefore, the wiring that is in an older home may be severely outdated and unable to cope with the load requirement of some modern technological appliances. It also means that it may be weathered and worn and unsafe to continue using.

2. If you have experienced a major storm recently.

South Australia can experience its fair share of wild weather and sometimes, extreme weather can cause damage to the electrical elements within a home. While you may notice any damage, it is also important to seek the qualified advice of a professional to ensure that any safety features and internal elements have not been damaged. It is especially important to have an inspection completed if appliances in your home stop working after a storm.

3. Before purchasing a new property.

It is strongly recommended that you have a building inspection completed before purchasing a property. While a building inspector will examine the structural components of your home and some minor electrical components, they won’t go into much depth. They may flick switches, check that you have smoke alarms and monitor some appliances, but to ensure your home’s electrical integrity, having an in-depth inspection completed is strongly recommended.

Your electrician will be able to identify in more depth, any significant electrical issues that your home may experience and take a closer look at the wiring that is installed. You can never be too sure of what work the previous owner may have had done in your home, or if they even used a qualified and licensed professional. Having an inspection done will ensure that you do not get presented with a hefty bill or an unsafe home after purchase.

Why Should You Get An Electrical Inspection?

1. To identify any faulty wiring.

Faulty wiring is a common cause of fires and injuries by electrocution. As mentioned, every year in Australia, there are roughly 300 people admitted to hospital as a result of electrical malfunctions within their homes. Electrical wiring has a certain lifespan, so just because it may have been safe ten years ago, doesn’t mean that its age hasn’t impacted its safety today. Many old homes have never had their wiring upgraded and wiring safety and efficiency have come a long way in a short span of time. Power and lighting circuits are now required to all be on individual safety switches. This came into effect in 1991, so if your home was built before that, then chances are your electrical system is non-compliant and not protected.

2. To notice any issues with your smoke alarms.

A smoke alarm can help save lives by providing you and your family with a strong warning if there is a fire in your home. Legislative requirements state that it is compulsory that ALL South Australian homes be fitted with a working smoke alarm and there are a few rules and regulations as to where the smoke alarm should be located and whether there should be more than one. Smoke alarms are now required to be hardwired, with a battery for back up.

Many injuries and fatalities from fires in Australian homes would have easily been prevented if a smoke alarm was present, or if their smoke alarm was working. Over time, some smoke alarms have become outdated and no longer comply with Australian standards.

During an electrical inspection, the electrician will note your smoke alarms location/s, whether you have enough in your home and whether they are working and compliant.

3. Identifying overloaded circuits.

Electrical circuits are designed to have a limited amount of electrical current. An overloaded circuit occurs when there is more demand on the circuit than it can safely handle.

If your home has limited outlets, you can be tempted to utilise multiple powerboards which would increase the demand on the circuit. When the limit is exceeded, the circuit breaker should trip, shutting off the power and removing the threat to your safety. If the circuit breaker was to fail, an overload on the circuit would cause the wiring to overheat and the wire insulation to melt, which may result in a fire.

Electrical installations can age and can become overloaded very easily, particularly in old homes where the wiring was not designed for the number of electrical appliances in use today.

The most obvious sign of an overloaded circuit is the circuit breaker tripping and shutting off the power. However, some other signs to look out for are:

  • Buzzing outlets or switches
  • Outlets or switches that are warm to the touch
  • Burning smells
  • Power tools or appliances that seem to lack power

During an electrical inspection, the electrician will identify the electrical demands of your circuits and provide you with any corrections that are necessary to avoid serious threats to your safety. These corrections may be the installation of new and additional circuits or reducing the load on each existing circuit.

4. Ensuring that your home’s electrical system is up to code and is compliant

There are certain electrical standards that your home’s electrical installation and wiring must comply with. It is impossible to know what type of work has been done on your home previously, and whether the previous owner used a licensed or unlicensed technician.

Understanding the current state of your electrical system is extremely important to be aware of your level of safety within your home and how much money you may need to pay to fix the legal issues.

In Austalia, it is illegal to complete your own electrical work if you are not a qualified tradesman. Licensed tradespeople have the equipment, training, certification, and knowledge to do the necessary work safely and in accordance with appropriate regulations and rules.

Conclusion

For the safety of you and your family in your home, it is clear to see why spending a little bit of money in the short term on an electrical inspection, may save you much more in the future, including your lives. Have a qualified electrician inspect your home or business’s electrical system to ensure that it is compliant and running as it should be.

 

 

 

Why Should You Have Your Air Conditioner Serviced?

Why Should You Have Your Air Conditioner Serviced?

Having your air conditioner serviced before the hot weather hits is smart for two reasons. Not only does it mean that you will be prepared for when the temperature starts to rise, but it also means that you will beat the rush of people trying to get theirs serviced during summer.

What Is Done During A Service?

During a scheduled routine service, a Green Efficient Living technician will complete a number of checks on the outdoor unit and indoor unit to ensure its compliance and that it is operating as it should.

The first thing that our technicians do will ask you whether or not your system is functioning properly. Have you heard any noises lately? Has it been playing up or not running as it normally would? Etc.

The return air will be then taken out and checked over, during which time our technicians run your system to inspect the outdoor unit. They will get the pressure readings, check electrical voltages and currents and ensure that there is no debris on the rear coilers of the unit.

After the service of the outdoor unit, they will then get into your roof to inspect that all electrical terminals are still tight, that the ductwork does not have any imperfections such as rips and that the main condensate drain isn’t blocked. During this time they will also inspect all zones by turning them on and off to ensure that they are all opening and closing as they should.

An example of dirty air conditioner filters covered in dust
Our technicians attended a service call for a faulty air conditioner and upon further inspection, the issue was simply dirty filters.

Can You Service Your Own Air Conditioner?

There are basic maintenance jobs that you can do yourself as the homeowner, such as cleaning the filters and ensuring that the outdoor unit stays unrestricted (see our post on that here). But when it comes to a complete annual service of your unit before using it again, this MUST be left entirely to the professionals. The smallest of attempts at servicing your own air conditioner can lead to serious unit damage or even electrocution!

Why Should You Have Your Air Conditioner Serviced?

The easiest way to understand exactly why you need to regularly service your air conditioner is for the same reason that you regularly service your car. You do not drive your car unserviced until it breaks down beyond repair and you are forced to buy a new one. Instead, you service it regularly to AVOID any serious breakdowns – an air conditioner is much the same.

There are many reasons why having your air conditioner professionally serviced is important:

1. It improves energy efficiency and saves you money on your electricity bills

Without periodic maintenance, your air conditioner will find it hard to run in prime condition. When this happens, it has to work a lot harder and consume more energy which in turn costs you more on your electricity bills! Avoid paying more by having a professional complete a service on your air conditioner to ensure that it is running as efficiently as possible.

2. It improves air quality

When your air conditioner isn’t working efficiently, it cannot properly filter the air is distributed into your home. An air conditioner that is running in perfect conditioner successfully filters out pollutants, pollen, dust and allergens, meaning the air that you and your family are breathing is cleaner and safer.

3. It extends your unit’s lifespan

Regular servicing and maintenance will extend the lifespan of your unit for all of the reasons mentioned above. It faults are left undetected, they can cause serious issues for your system in the future. These issues may result in costly repairs or even a unit replacement! However, by servicing it regularly you are increasing your system’s lifespan and keeping it running in perfect working order for many more years to come.

The professionals at Green Efficient Living recommend having your unit serviced annually, even if it is not showing any signs of faults or issues. To book your annual service, call us today on (08) 8297 3422.

Note: Green Efficient Living is currently holding their annual Pre-Summer Service Sale! Take advantage of our discounted prices and have your unit serviced before the hot weather is here!

Why Should You Swap To LED Lighting?

Why Should You Swap To LED Lighting?

We’ve heard it all before: ‘change your globes to LED globes!’ But why? Are LED globes really as good as they say? Is there really any point spending time and money switching your existing globes to LED ones? Why are LED globes so good?

LED stands for Light Emitting Diode and is an increasingly popular alternative to your standard halogen, incandescent, or CFL (Compact Fluorescent Lamp) globes. If you haven’t already substituted your current globes for LED ones in your home or business, then your lighting would already contain one of the other three options mentioned.

What Are Your Lighting Options?

Firstly, let’s look closely at the other traditional options. Not too long ago, you had the choice of incandescent globes, halogen globes, CFLs and LEDs however, it has been predicted that halogen lights will disappear from Australia within the next two years as the country shifts towards more efficient and environmentally options. Australia began the phasing out of poor-performing incandescents in 2007, requiring homeowners and businesses to instead install energy efficient lighting to cut greenhouse gas emissions. Then in 2010, the Australian Government then enacted a ‘Minimum Energy Performance Standard’ law ensuring only the highest performing products are to be available. However, these standards relating to incandescents, halogens and CFLs still do not meet the same energy efficiency as LEDs.

CFLs

Your CFL bulbs are reasonably cheap to buy but can cost you more to run over time. They can also wear out faster if put in a light fitting that is switched on and off constantly, such as your bathroom or kitchen. They can’t be used outside very often as they don’t work well in extreme heat or cold and can take a little longer to reach maximum brightness. They do, however, have a slightly longer lifespan than incandescents and halogens, and are slightly more energy efficient.

They work via a chemical reaction known as fluorescence. The tube contains mercury that becomes ‘excited’ as electricity is passed through the system. When the mercury begins to settle, it gives off light.

Image showing a CFL Globe
An example of a traditional CFL globe.

Incandescent Globes

Incandescent globes were simple and cheap to manufacture and therefore purchase, but besides that and their bright light, the pros stopped there! Their lifespan is extremely short and they lose around 90% of their energy to heat. However, despite this, they were probably the most common light bulb that you had in your home currently until the government placed a heavy regulation on the sale of incandescents operating at a certain energy efficiency.

Incandescent globes have the classic ‘light globe’ shape. They contain a mental filament made of tungsten inside, that acts as a bridge for electricity to flow over. As the electricity surges, the filament heats up and it begins to glow giving off light. This is also the reason why the globe gives off so much of its energy as heat, and why it is often hot to touch straight after it has been turned off.

Image showing incandescent globes
An example of traditional incandescent globes. These are the most common globes that you might recognise.

Halogen Globes

Halogen globes are a type of incandescent light, however, are stronger, designed to withstand higher pressures than incandescents and are around 30% more efficient. But while they are labelled as ‘low voltage’, they still use approximately 35W to 50W per globe, so they are still not an efficient choice to have within the home. They can also become quite hot and can, in some circumstances, becomes quite hazardous.

An example of a traditional halogen globe.

LEDs

LEDs are often the more expensive option to purchase per globe compared to their more traditional counterparts, however, they are longer lasting and much cheaper to run! Using around 75% less energy than CFL globes and lasting two to three times as long, when we look at LED globes in comparison to the other options, it is clear to see just they’re the obvious choice!

An globe displaying LEDs
An example of an LED globe.

What Are The Benefits Of LEDs?

Energy Efficient

The first and most beneficial reason is that they are extremely energy efficient and will save you money on your electricity bills. They use less power (watts) per unit of light (lumens) and can, therefore, provide up to around 100 to 200 lumens per watt. In contrast, CFL globes use around ten times the amount of Watts as LED globes. Incandescent globes also lose a lot of their energy to heat rather than light (90-95% to be exact), so they are extremely inefficient to run. For reference, a 60W (watt) incandescent bulb will only put out as much light as an 8W LED bulb! It doesn’t really make sense to put these globes in your space, when 95% of what you are paying for, you are not able to utilise. So while they might seem the perfect option upfront due to their low cost, they are considered a much more inefficient option than LEDs. In a typical Australian household, lighting makes up for about 7-10% of your electricity bill (sa.gov.au). So when you think about how much you rely on lighting in your home to live comfortably, ensuring that you have the most energy efficient lighting is a small change that you can make to save big on your bills.

Graph showing the average energy usage in Watts per Lumens for typical globes
Above you can see a comparison of the average energy usage in Watts per Lumens of typical globes. You can see that the brighter the globe (lumens) the more energy it consumes (watts), as you would expect. However, LEDs remain the lowest option!

Longer Lifespan

Another positive is that they have a much longer lifespan than other traditional globes. To put it into perspective, an average lifespan of an LED globe is between 15,000 to 50,000 hours, while halogen globes last a mere 1,000 to 5,000 hours. So the need to consistently purchase and change your globes lessens when you purchase LED globes. That means less money spent on always buying new globes!

Chart showing the overall lifetime costs of different globes
A 10W LED bulb would cost $39 in total to buy and run over 10 years. Over the same about of time, five 42W halogen globes would be needed at a cost of $148. or two 12W CFL bulbs at a cost of $48.

Environmentally Friendly and Recyclable

LED lights are non-toxic, better for the environment and your family and currently the greenest choice on the market today! CFL globes, along with fluorescent tubes, contain a small amount of mercury, a requirement of 5 milligrams according to Australian Standard (environment.gov.au). While this amount of the toxic mercury does means that handling CFL bulbs requires more care and precautions, the short-term nature of the potential exposure when broken does not create a potentially large risk. Gloves should be worn to clean up a broken or no longer working CFL bulb and the remnants should be placed in a plastic bag and given to a nearby waste or disposal centre to avoid the mercury from entering the environment. To find a centre near you, head to www.recyclingnearyou.com.au. Incandescents and halogen globes cannot be recycled due to the fact that they contain a Tungsten filament that cannot be reused, but they may be able to be taken to the same recycling centres as CFLs. The best way to dispose of these globes is to simply wrap them in a few layers of paper and throw them in the garbage, not the most environmentally friendly option, or call your local disposal centre to see if they will take them. LED globes, however, do not contain any hazardous materials, are not made of glass and are completely recyclable. So if they break or stop working, simply wrap them in paper and place in your recycling bin! Safe on your family and the environment!

More Flexible Lighting Options

LEDs are considered to be ‘directional’ light sources, meaning that they can be designed to emit light in a specific direction. Those with LEDs installed in their homes can look forward to focused and concentrated light because of this, and a more energy efficient result. Incandescent and CFL globes emit light in all directions, meaning that they are often radiating heat and light in directions where it is not needed, wasting energy and your money. Having the ability to focus your lighting in your desired direction, means that your lights do not have to work as hard to illuminate the space, and therefore your energy bills stay lower.

LEDs can withstand frequent switching on and off making them perfect for outdoor flashing light displays, sensor lighting, or in areas such as the kitchen, or bedroom where lighting is commonly turned on and off. As well as this, LEDs are able to to be successfully dimmed. Most traditional lights can only be dimmed to 30% of their light output before they stop working, but LEDs are able to operate at a mere 10% of their light output (when used with LED suitable componentry).

Durability and Safety

As previously mentioned, LEDs are much more durable and able to withstand harsh weather conditions due to their ability to operate under extreme temperatures and low voltages.  This enables you to place them anywhere around your home, indoors or outdoors, as the cold, wind, rain and extreme heat will not affect them. LEDs also do not contain any filaments or glass enclosures but are instead mounted on a circuit board with soldered leads. This makes them virtually unbreakable and able to withstand shocks, vibrations and external impacts. Safety is no concern with LEDs as they do not give off heat and contain no harmful chemicals.

While different globes work for different situations, it’s obvious to see why LED globes are the clear choice to have within your home or business. With halogens and incandescents slowly being phased out, the only competition that still stands are the traditional CFL globes. Despite CFLs still being a good choice, the benefits of LEDs in comparison far surpass those of CFLs.

Micro Inverters VS String Inverters

Installation of a Fronius String Inverter

Should You Get A String Inverter or Microinverters?

If you are considering having a solar PV system installed on your home or business, one of the key decisions that you will have to make is whether to have a string inverter or micro-inverters installed.

Inverters play a crucial role in the production of solar energy, so it pays to choose the right one. When the sun hits the solar panels, the light energy is transformed into direct current (DC). Unfortunately, your house or business runs on alternating current (AC) and therefore an inverter is needed. The inverter converts the DC into AC to make it accessible to your home or business.

There are two main types of inverters that your solar power system can use – string inverters and microinverters. Depending on certain factors such as your location, energy needs, energy usage patterns, amount of shading on your home, one type of inverter may be better suited to your system than the other. Green Efficient Living is here to help you decide which one is better for you.

String Inverters

A string inverter, or central inverter, is a large box that is generally located on the wall on the outside of your home, or close to your fuse box/electricity meter. There is usually one, maybe two, string inverters on each residential solar installation and they operate in series array or series circuit.

Microinverters

Microinverters perform the same role as string inverters, however, they are much smaller and designed to sit underneath each individual panel. They accept the current of each panel individually rather than a series of panels collectively. This ultimately means that there is the same number of inverters on your roof as there are panels.

So Which One Is Best?

There are many factors that need to be considered when deciding which inverter type is right for you. Your solar installer will have to look at which direction your roof is facing, how much shade it is receiving, your energy production goals and much more, before determining which inverter is right for your system. Independent of those factors, however, there are major differences between the two types of inverters.

System Performance and Energy Output

One advantage of microinverters is that there is never a single point of failure that can affect the whole system. As microinverters operate independently of one another, they result in a more effective output overall. This means that if an outside influence such as shading from dirt and grime, overcast weather conditions, overgrown vegetation, etc. cause an effect on one panel, the entire system’s performance is not compromised.

However, systems with string inverters risk losing their entire system’s maximum performance if one panel becomes affected or fails. As they are connected in series, if one panel is affected by outside influences (mentioned above) or performance failure, then your entire system will not function to its maximum potential. The rest of the unaffected panels outputs will drop to match.

Winner = If your roof receives shading, or you’re in an area that receives a lot of cloud cover, then microinverters are your best option for maximum production. 

Safety

When having microinverters installed, there is also a reduced safety risk as they operate at a much lower voltage than string inverters. As string inverters accept the voltage of the entire system, you can have up to 600 volts DC on a domestic system, or more, running through your home. If this voltage were to arc, your system will fail, a large bang may occur, and in worst cases, a fire may result! This is why it is paramount that you find a reputable installer to ensure that your system is installed to the highest quality.

Winner = Microinverters have been labelled as the safer option as they eliminate the need for this high voltage wiring. 

Flexibility and Expansion

String inverters have a limited number of panels that they can accept, so depending on how many panels are already in your system, you may find it hard to add more at a later date. Microinverters allows for increased expansion in the future – all that you will need to do is add more panels and more inverters. Their independent operation also means that you are not limited when it comes to their orientation either. You can add panels on any side of the roof, at independent angles, and still yield the same amount of electricity. However, with string inverters, all of your panels must be connected in the same orientation and facing the same way.

Most string inverters, however, do have two independent inputs, or mmpt’s. This means that two arrays of panels can work independently of one another via the same inverter.

The overall panel production for the above image. Notice the difference in overall production between each panel thanks to the installation of microinverters.

Winner = Microinverters allow for your system to be expanded in the future as well as a lot more flexibility with your panels positioning and orientation.  

Cost

While prices may vary between states, installers, manufacturers, etc. statistics show that microinverters are still the more expensive option.

However, cost does not only cover the initial expense up front but also the overall savings that you will receive throughout the life of your system and the speed at which you recuperate your initial expenses. While string inverters may not be a larger initial expense, your overall production will be greater with microinverters and therefore may result in larger savings on your bills in the long run.

Winner = For an initial lower cost, string inverters are the better option. However, for long-term investments, the upfront costs of microinverters will be recouped over the lifespan of the system. 

Maintenance and Repair

One large advantage of microinverters is their panel-level monitoring. While the homeowner is not able to see the individual values of production, your technician has access to each inverters performance via a system monitoring program. This means that they can easily monitor how your inverters and panels are performing without the need to perform an inspection. String inverters can only let your technician monitor the system’s overall production.

However, as microinverters are located on the roof of your home, maintenance and repairs can become a lot more costly and time-consuming. If a panel or inverter develops a fault, your technician will have to get onto the roof to have access to your inverters and panels.

A string inverter, on the other hand, is more cost-effective and timely to repair as it is located on the wall of your home down on the ground. This means that your technician avoids the lengthy process of having to get onto your roof to repair the fault.

Winner = There are definitely pros and cons to both. System and fault monitoring are easier in microinverters, however, maintenance and repair are easier in string inverters. Microinverters also have the added ease of service should it ever come to needing to claim your performance warranty.  

VERDICT

Both string inverters and microinverters have their pros and cons. While it may seem that microinverters are the clear winner, this is not always the case. Should your home and roof receive minimal shading, your energy usage be predominantly throughout the day, and you have no intentions to expand your system in the future, then there is no reason why you should not use a string inverter. However, if your roof is one that receives shading in certain areas throughout the day, then microinverters may be the better option.

Your solar installer should be asking you a number of questions during your consultation to distinguish which inverter will benefit you the most.
