Top 10 solar companies in Perth WA by customer satisfaction data

When every solar company is a self-proclaimed number one, how do you truly discern the Top 10 solar companies in Perth? Some companies reference a nominated quarter in a year long gone where they installed the most volume as a No.1 accolade. Others have no justification at all, simply if they say it enough, surely you’ll believe it. Gauged over the last decade, a data-backed answer exists.


When making an energy security investment such as installing solar panels, customer satisfaction over time trumps installation volume in a narrow period. Enduring Time provides the scope of both past and present customer satisfaction, for example, how well a company performs in the event of after sales care, or how likely a company is structured to weather industry highs and lows.

Customer experience is now available for most to see through varied online review platforms. However, these too can be a little skewed, especially platforms that require a paying contribution for retailers listed as Top 10 Solar Companies in Perth. This raises another interesting question, which review platforms can be trusted? As it turns out, the most transparent reviews where a large portion of purchasers perform solar-specific research are on Google & Both platforms provide customer insights into all companies across Perth as not all companies exist on paid subscription platforms such as Product Review.

Therefore, if a company is genuinely at the top of its game, it would be plausible to suggest its customer experience (reviews) be evident through consistency across almost all review platforms, even those that they aren’t monitoring or subscribing to.

Finally, volume or sample size is critical. It’s too easy for organisations to delete poor reviewing accounts, recreate their accounts, and get family and friends to boost a five star review rating. If you’re one of the Top 10 solar companies in Perth over time, less than one hundred reviews doesn’t cut it in most people’s eyes.

The answer to the top 10 solar companies in Perth should be data-driven, using publicly available information. Consider this list your ultimate guide to selecting a reputable installer equally invested in your energy security for the long-term.

Discerning different review platforms

Certain review platforms seem credible. Many national and high-volume companies have a large number of reviews on marketing machines such as Product Review and Trust Pilot. These platforms lose credibility when they give premium subscribers (solar companies) the ability to weed out negative sentiments before the review is posted. Nonetheless, comparisons on alternative platforms such as, can assist in identifying a more reflective average score. comes with a warning. The volume/sample size is heavily weighted to its own subscribers – solar companies that purchase leads. While quotes are free for the customer, charges three local installers for the privilege to quote on a project. There’s nothing wrong with this, as the website produces good research content for the energy investor, and they must be paid somehow. Companies that subscribe to are easily identifiable. They earn the badges silver, gold and platinum. Many solar companies that have a healthy internet presence or good word of mouth don’t need to spend money on leads. Unfortunately, these solar companies don’t look as appealing without the badges, but that’s a cost a company must be willing to wear or save their customers.

A place that was rife for purchasing reviews in the previous decade was Facebook. Although, a large question mark exists surrounding Facebook reviews for comparing the Top 10 solar companies in Perth. On the plus side, it seems to be a platform Microsoft is advancing towards for its new ChatGPT-integrated Bing search engine as competition to Google. Evidence credibility could be returning to Facebook reviews in the future. There’s a while to go in this space yet. 

Every Top 10 solar company in Perth is aware of Google reviews. Google reviews are for everyone, not just product purchasers. How a solar company interacts with a potential customer through to aftercare service from purchasing customers. Quite simply, it’s important to be on your best behaviour at all times with Google reviews for solar companies. Google reviews in the early years had the potential to be dubious among certain solar companies, but now are better regulated. Be weary of low review counts from established solar companies. Google business accounts are easy to delete and restart again if the reviews aren’t trending the way they would like.
