How we rate solar installers in Australia


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 seven of the most prominent installers in Australia, there may be other companies available in your area. 


Canstar Blue surveyed 1,471 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.

  • The outcomes reported in these ratings are measured via ISO 26362 accredited research panels managed by Qualtrics.

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:

  • Overall satisfaction: measured consumer satisfaction with a solar installer as an individual score NOT a combined total of all criteria.
  • Customer service and advice: the solar installer had multiple service points for customers, e.g. telephone, email, online chat and helped customers determine their solar needs.
  • Performance of solar system: the solar installer provided products that performed to its needs or greater.
  • Installation process: the solar installer had a smooth and simple installation process for customers.
  • Durability: the solar installer provided products that were durable and performed to its needs, even in extenuating circumstances. 
  • 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.

  • Overall satisfaction is asked as a specific question and represents an individual measure, not a combined total of all criteria.
  • When we cannot determine a clear winner from the criteria for the Overall satisfaction rating, we will then look at the other criteria measured in the rating.
  • The brand with the highest number of five-star ratings within the supporting criteria will become the five-star recipient in overall satisfaction, and thus win the award. If a clear leader still cannot be determined from the supporting criteria, joint winners will be declared.

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.

FAQs about solar installers

With 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. 

  • Cherry Energy Solutions
  • Energy Aware
  • Enervest
  • Evergen
  • GEM Energy Australia
  • Iberdola Australian Smart Energy Solutions (formally Autonomous Energy)
  • ITP Home Energy
  • Lighting and Energy Conservation Australia (LECA)
  • Next Generation Electrical
  • Off-Grid Energy Australia
  • RACV
  • SAE Group
  • Springers Solar
  • Sunboost

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: 

  • 42% said they picked based on the quality of solar panels and parts on offer from the retailer
  • 40% said they chose an installer based on the price offered
  • 13% said they went for a retailer with good customer service
  • 5% listed another reason why they picked their installer

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.

  1. How much experience do you have installing solar systems?
  2. Are your installers Clean Energy Council accredited?
  3. Will I be able to claim a government subsidy/solar rebate and how do I do that?
  4. What size solar system do you recommend I install? Is there room to expand later?
  5. What are the upfront costs for the solar system? Do you offer payment plans?
  6. Who should I contact if there is a problem with the installation or system?
  7. What panel/inverter/battery brands can you install?
  8. Is the quoted cost all-inclusive or will I have to pay extra fees later?
  9. What does the warranty cover?
  10. In what circumstances would the warranty become void?
  11. How much should I expect to receive from my solar feed-in tariff?
  12. How often should I be carrying out maintenance on my solar system? Does your company send reminders/notices?
  13. Will I be able to add battery storage down the track?
  14. How can I track the production of my solar system?
  15. What is the life expectancy of this system?

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:

  • Make sure the company is actually out of business: Unfortunately, there are quite a few ‘shady’ businesses out there that may avoid contact attempts years down the track. Check to see if your installation company is still registered with an ABN before proceeding. If it is still in operation, take action through your appropriate fair-trading agency.
  • Directly contact your solar installer: If a company is genuinely out of operation, the individuals that installed your panels may have more information for you. The Clean Energy Council has a comprehensive list of accredited solar installers with contact details on their site.
