SunWiz researched the reviews of every Australian solar company, because we discovered consumers may be misled by overlooking the context of solar installer reviews. 
 
Our research revealed 50% of solar businesses have a 5-star Google review rating. 
 
“50% of solar businesses have a 5-star Google review rating”
 
That makes it impossible to sort the good from the great. Looking for a great solar company shouldn’t be like looking for a needle in a haystack.
 
Even more concerning, and potentially resulting in customers making poor choices was this finding: 4.2 star google review rating puts you in the bottom 17% of all installers.
 
“A 4.2-star google reviews rating may be decent for a restaurant, but it’s it makes you one of the worst solar companies in Australia”
That’s why SunWiz created the Best Rated Solar Retailer awards: to help customers make good decisions by identifying the best of the best. 
  • We compile information from more than three commonly used review sites, and eliminate bias by only including retailers with strong results across multiple platforms, which we then perform a weighted average upon. 
  • We exclude retailers with less than 100 reviews, to help customers truly identify the most popular companies.
  • We observe that it’s extraordinarily difficult to maintain a perfect 5-star rating as you get bigger. So we only include retailers with >100 reviews and >4.8 star rating. That puts these businesses in the top 100  best-rated solar businesses in the country. 

Being recognized as one of the top-rated solar retailers by customers is a significant accomplishment that showcases the retailer’s commitment to delivering exceptional customer service and quality products. Achieving high ratings from customers is no easy feat, as it requires consistent dedication to meeting and exceeding customer expectations. Customers are likely to rate a solar retailer highly if they have received reliable and efficient service, timely installation, and a competitive pricing structure.
