Aussies have rated Solargain their top pick for Australian solar installers in 2025. The popular brand achieved a perfect five-star rating in all of our research categories.
It goes without saying that solar installation isn’t always black and white, with so many installation companies on the market claiming to have the cheapest prices and best service. If you’re a first-timer, it’s not always clear what your best options are. And that’s where we come in.
Canstar Blue has taken the guesswork out of choosing a good solar installer, by collecting the opinions of those that have already installed solar across Australia. We’ve asked them to rate their solar installer on variables such as customer service and advice provided, performance of solar system, installation process, durability and set-up cost, in order to help you find one that suits your needs. Please note while this review looks at some of the most prominent installers in Australia, there may be other companies available in your area.
Canstar Blue surveyed 1,659 Australian households for their feedback on their solar panel installer. Respondents had to have solar panels at their property by a professional solar installation company in the last five years for their response to be eligible.
Respondents rate their satisfaction with their solar installer from zero to ten, where zero is extremely dissatisfied and ten is extremely satisfied. Provider satisfaction was rated by respondents on the following criteria:
Set-up cost: the solar installer had a decent cost for the services and products provided.
The winning brand is the one that receives the highest Overall satisfaction rating once all the scores from the Overall satisfaction criteria are combined and averaged.
Brands must have received at least 30 responses to be included, so not all brands available in the market have been compared in this survey. The brands rated in this survey are listed below in order of best overall satisfaction.

Meet the Research TeamWith thousands of solar installers in the Australian market, it’d be impossible to name them all. Instead, we’ve compiled a list of some of the more well-known solar energy installers around the country that haven’t been included in this year’s review. Please note, there may be more solar installers available in your area.
If you are a beginner when it comes to installing solar there are a few things you’ll need to keep in consideration. The type of system you’ll be able to get will depend strongly on factors such as your roof size and style, household positioning and your personal budget. It’s your solar installer’s job to assess your roof and lay out your options in the form of a quote. And with most solar installers offering different options at different price points, it’s not always crystal-clear which installer to go for.
As part of our ratings report, we asked survey respondents to share what the biggest deciding factors were for them when picking their solar installer. We’ve listed these below:
A New Tech Energy Approved Seller is a provider who meets the requirements set out in the New Energy Tech Consumer Code (NETCC). This code is a set of standards designed to protect consumers when they are purchasing new energy tech such as solar panels, solar batteries, electric vehicle chargers and the like.
If an installer has this approval, it means that they have demonstrated that they meet the requirements of the NETCC and that it is committed to remaining compliant with the standards outlined. You can check whether your installer has this badge of approval by searching the NETCC database on its website.
The NETCC program is administered by the Clean Energy Council (CEC) and replaces the previous CEC Accreditation and CEC Approval in the solar market.
Best case scenario, your solar panel installer will provide you with all the information you could possibly need. Though, in some situations, it’s best to have a log of questions prepared to help you pick the right installer for you.
Choosing a solar installer can be hard for many reasons, a big one being that you’ll be relying on sometimes decades of service from the same company. Any good installer will conduct maintenance on your PV system during its life, whether that’s scheduled or necessary due to complications. So, what do you do if your solar installation company goes out of business? Here are some steps you should take:
