With enough time, the best solar companies Perth has to offer begin to surface. Over a decade of mainstream popularity and with the internet as a popular research tool, customer satisfaction levels have become apparent with long-standing companies. Companies that have yet to stand the test of time still have untarnished review profiles, or often noticed is the resetting of Google listings to wash away past negativity. However, the review count is evident and easy to determine for any discerning investor.

Every day, a solar company defines itself as Perth’s number one installer, but by what measurement? If it’s volume, that provides little insight into how a company treats their customers (long-term), especially if the capacity achieved is from completing a few very large jobs in a nominated period. Some will hold onto the highest volume credential in a time that is no longer relevant (consumer expectations have changed in 2025). However, the gauge most customers seek is how the considered best solar companies in Perth evolve while attending to their customers over time.
For added depth of research, combine this with leading international business assurances such as ISO-certified business processes and NETCC consumer endorsement for a more defined solar company. Advantageously, Perth’s customer satisfaction averages and solar company certifications are available.

Two reviewing platforms, Google and SolarQuotes.com.au, provide a level of commonality among all of the best solar companies in Perth. Alternative platforms exist, such as ProductReview and TrustPilot, but these are marketing machines that reap the rewards when organisations subscribe for benefits and the ability to pre-screen negative sentiment through review gating. Appealing for some but not the most transparent gauge for customers.
Google is open slather for everyone. It’s an excellent tool to ensure companies are on high alert, even those that have yet to purchase from them. Always be wary of low review counts and no mixed opinions.
Tip. Even though Google has improved legitimacy, spot dubious reviews when comparing:
- The number of reviews reviewers have made.
- The average review content/length (Short = Less good. Longer = Better).
- Assess the lowest reviews to see how a company responds to dissatisfaction.
- A small amount of dissatisfaction is a good thing. It provides a benchmark for evaluating the business and its performance in adverse scenarios.
SolarQuotes.com.au is contentious because paid elements exist for installers. Therefore, solar companies that purchase leads from solarquotes.com.au naturally have more reviews than those that don’t, as the platform always follows up the experience should a lead-purchasing solar company win your work. Unlike alternatives, SolarQuotes.com.au reviews are good for purchasers identifying different elements of installer competency. Those among the best solar companies in Perth have customer reviews here – even the non-subscribers, as SolarQuotes.com.au is a popular customer research tool for most.
SolarChoice.com.au is similar to the SolarQuotes.com.au website. The installer review section is new, so the review count for most currently considered ‘top-rated Perth solar companies’ is low. SolarChoice.com.au’s online content is detailed and free for serious sustainable energy investors doing their research. Due to trust with search engines, solar companies have their reviews prioritised through SolarChoice.com.au ahead of alternative platforms.
Facebook’s business reviewing mechanism is as credible as Facebook Marketplace before 2023. It had been rarely supported, and reviews could be purchased from vendors that many exploited. Perth Solar Warehouse Facebook recommendations are genuine but urge customers to exercise caution when comparing companies here.

1) Time is an outstanding measurement. Given that most warranties are 10 years or longer, you need a company that’s been around 10 years or longer a proven history of customer experiences. Your solar investment is only as good as its installation company, simple. The longer, the better. Ask yourself, are you buying a dream or a proven energy supply? Choose a company whose guarantee compliments its operational history to improve warranty assurance.
2) Diverse satisfaction. The internet is much bigger than one review platform, solar companies often focus on one review website for the unsuspecting purchaser. Comparative reviews on alternative media streams suggest differently and provide greater insight, adding great weight to Perth’s best solar companies.
3) Review count of aligned platforms. Ignore our choice of reviewing websites. Find multiple platforms that your shortlist of best solar companies has in common—any two or three, but make sure they are the same website (substitute websites don’t qualify). Consistency is what you want to see. Hone in on inconsistency.
4) Locally based, as dealing with eastern state businesses (or foreign support agencies) could be more fun. Homegrown organisations are hands down the best solar companies in Perth. Local business gets you! Perth Solar Warehouse understands local needs and can better assist at times of support. The world is on a sustainable energy journey from 2025. You deserve local knowledge and experience for expansion options, when you need it.
5) In-house installation options give customers the system execution assurance they desire. A close-knit solar installation company is more likely to receive regular product care and safety training. The ideal time to perform the job correctly provides no complications regarding installer to company warranty disputes.
5) Visual competency away from stock images (there is a contrast). A genuine solar company proud of its workmanship will display its results regularly through social media so prospective customers can understand what to expect towards an end result. Most won’t. There is a choice: proven aesthetics or the unknown.
6) A Goldilocks company. Not too big, where customers are simply another cosmic element. Not too small, where business stability (warranty certainty) varies. We’re just right as your future energy partner. A solar company invested in your results is personable and approachable, with a defined evolution.
Proven. Local. Perth Solar Warehouse: Unit 3/90 Discovery Drive Bibra Lake, Western Australia.
Some solar companies have reviews. Others have experiences. Depth over time is important in this scenario. The volume of high-level experiences over time can act as a significant value for an informed buying decision. Over 1400 experiences on comparative platforms. Perth Solar Warehouse customer experiences spanning the last two decades:
- Google: 4.9/5 greater than 700 reviews
- SolarQuotes.com.au: 4.9/5 greater than 600 reviews
- Facebook: 5/5 greater than 80 recommendations
- SolarChoice.com.au: 4.8/5 greater than 30 reviews
- Oneflare: 4.9/5 greater than 700 accumulated reviews
Tip: Compare the best solar companies in Perth on low-review-count platforms (platforms with less than 50 reviews). Low-review-count platforms ensure a company doesn’t drown out the negativity on key targeted platforms with reviews that lack substance. A high volume of 0 to 5-word reviews isn’t an experience.
Manufacturers rely on dependable local solar companies to implement their products at ground level, regardless of an individual’s accreditations. SAA-accredited installers bounce around from business to business, often with little concern or regard for previous projects. Warranty concerns can often arise with complexity relying on an idividuals SAA-accreditation alone. Manfacturer-certified, industry-endorsed partners are the best solar companies Perth customers should seek out. These solar companies will most likely be more knowledgeable about a manufacturer’s recommended installation practices through required continuous professional development.
