Top Solar Installer Ratings – Best Of The Best
To reward the best solar power installers in Australia currently active in the SQ network that consistently get rave reviews from their customers posted on this site, I’ve developed a legendary / platinum / gold / silver rating system. The level of award is automatically calculated based on these 2 criteria:
- How many 4 and 5 star reviews they’ve received within the last three years
- The average score of all their reviews within the last three years
Our leaderboard ranking algorithm updates this list approximately once a month, and was last updated on December 7, 2025.
- At least 200 reviews
within the last 3 years - Average review score:
at least 4.85 / 5.0
