If you'd like to know more about how solar works you can take a look at our handy solar guide. It explains the ins and outs of solar, including handy tips on what to look out for in terms of systems, providers and installation, along with how much you can expect to save off your electricity bills. If you can't find what you're looking for, then check out these FAQs.
It's a pretty simple process. Check out our handy solar guide for details.
Our handy solar guide shows you how much solar you can expect to generate each year based on the orientation and tilt of your panels, along with your potential electricity bill savings based on various system sizes.
In Canberra, solar connections are net metered. Check out our handy solar guide for more information.
STCs help subsidise the cost of your solar system. Check out our handy solar guide to find out what your approximate STC subsidy would be.
Yes, you will be entitled to a discount based on the number of STCs your system is entitled to generate. Check out our handy solar guide for information on STCs.
For your panels, there really is no maintenance required, except making sure your panels are kept clean and free from shade. These are preventable by pruning trees when necessary and arranging an annual clean of your panels.
Your local network provider requires your inverter to undergo a mandatory anti-islanding safety test at 5 year intervals. We can arrange this safety test for you, at your request.
Yes. Even though you mightn't be home during the sunniest part of the day when your solar panels are generating the most amount of energy, appliances like your fridge and freezer are still running. You can increase the amount of solar energy you use by setting other appliances like your dishwasher, or washing machine, to run during the day.
We can provide you with a quote within a few hours. Then, from the day you accept the quote it will typically take 4-8 weeks until you're up and running. This is because of all of the steps and parties involved in the process, including the meter upgrade, installation, safety inspection and system commissioning.
Yes, in order to have solar installed you need to own the home. If you are renting and want to install solar, you will need to provide us with written permission from the home owner and a copy of the rates notice.
Yes, solar panels can be installed on your shed provided you have the relevant approvals and your shed roof is capable of supporting the racking system. We would recommend a site visit to take a look first.
Yes, please let us know if this is the case. It will impact the position on your roof where your solar panels can be installed so that there is little or no impact on the appearance of your home from the street or another public area.
No, your off-peak hot water will continue to be separately metered as it is now.
Business customers tend to save more than residential customers for the same sized system because as a business, you typically tend to use more electricity overall and in particular, during the day when your panels will be generating the most amount of energy.
Check out our handy solar guide. In Canberra to maximise the amount of energy your panels generate, your panels should be installed facing north and tilted at 30 degrees to the horizon (most homes in Canberra have a 30 degree roof pitch).
Here's a comprehensive table outlining the generation you can expect if your panels are installed on a different orientation and tilt, taken from the Clean Energy Council's Grid Connect Design Guidelines handbook.
Panels should not be placed in shaded areas. Shade on just one panel can result in lots of panels losing power. Our handy solar guide contains more information on this.
No, many world-class panels and inverters are now manufactured in Asia, just like components and technology for other industries.
No, unless you don't have a lot of roof space. Essentially, ultra-efficient panels are just physically smaller but generate the same output as a normal sized panel. Panels that come with 15% efficiency are more than sufficient. Read our handy solar guide for details.
Most solar panels operate at 250 Watts (W). A manufacturer will provide a power tolerance rating for their panels, expressed as a plus or minus percentage (e.g. 250W +/- 10% means the manufacturer is saying that the panel could operate at 110% power = 275W, or 90% power = 225W, which is lower than you might have thought you were buying).
As mentioned above, you want to make sure you are getting the most power out of your panels. A positive power tolerance means the manufacturer guarantees the panel output will match or exceed the power rating provided. It also indicates the manufacturer has good quality control processes in place.
The performance ratio is an indication of how your panels operate under “real world” conditions vs lab conditions quoted on the panel's specification sheet. For example, a 250W panel that only produces 220W when tested under “real world” conditions has an 88% performance ratio (220 divided by 250). It's important to look for panels that perform at over 90%.
Basically, you should make sure that your panels, inverter and installation are all covered by these warranties.For panels, you should make sure you are covered by two warranties.
1. The manufacturer's product warranty (good quality panels come with a 10-year product warranty).
2. The manufacturer's performance warranty (good quality panels come with a 25-year linear performance warranty).
For the inverter, you should make sure you are covered by the manufacturer's product warranty (generally, most inverters come with a 5-year product warranty, so make sure you look for an inverter that has a reputable presence in the Australian market).
And for installation, you should make sure that your solar provider covers you with a workmanship warranty.
A linear performance warranty is important, as it provides you with a guarantee that your panels will perform at a higher output over the term of the warranty period, compared to a standard warranty. See the graph below for details.
Yes, the output of any solar system will gradually decrease over time. That's why it's important to make sure your panels are covered by a linear performance warranty, rather than a standard performance warranty.
Solar panels are generally installed all together on one area of your roof. This is called an array (for example, a 2kW system consisting of 8 panels would typically be installed on one section of your roof in the configuration of 4 panels across by 2 panels deep, called a '4 by 2' array).
A split array is when your panels are installed as two or more separate groups. This may happen if your north-facing roof space isn't large enough to accommodate all of the panels and a second array has to be installed on your west-facing roof. You may also need a split array if you opt for a large system and it's not possible to fit all of the panels together on one part of your roof.
'Mono' (monocrystalline) solar cells are manufactured from a single crystal of silicon and are typically black in colour. 'Poly' (polycrystalline) solar cells are made up of multiple crystals and their colour can vary from light to dark blue due to the different manufacturing processes involved. Choosing whether to go with mono or poly cells isn't as important as choosing solar panels based on the quality and reliability of the manufacturer.
An inverter converts the DC electricity generated by your solar panels into AC electricity that can be used in your home and fed back into the electricity grid. Read more in our handy solar guide.
It is important to look for an inverter with a higher 'Euro efficiency' rather than 'peak efficiency' because Euro efficiency measures efficiency over a broad range of load. See our handy solar guide for more info.
MPPT is short for “maximum power tracking point”, which basically means the electrical operating point of your panels can be varied so that your panels deliver the maximum amount of power. Most solar installations only need a single tracker MPPT inverter. You will generally need a dual MPPT inverter when you have panels facing different directions. For example, if half of your installed panels face north and the other half face east. Read our handy solar guide for more information.

Our buyback rate is set annually each July to reflect the ordinary cost of purchasing wholesale electricity.
There have been a number of government legislated feed-in-tariff schemes over the years, which have now expired, so this is why some people are receiving different buyback rates.
Yes, you can choose to pay the pre-STC price on your quote and keep your STCs if you'd like to.
The cost of solar has reduced significantly over the past 5 years, but it's unlikely that there will be such dramatic price drops in the future. In 2013, Choice advised that “Grid-connected solar systems are unlikely to cost any less than they are now”. So now is a good time to buy if you're thinking about investing in solar.
