Roof space and efficiency
Efficiency helps compare output per square metre. Module dimensions and usable roof area determine what actually fits.
Understand respected panel brands in Australia, the difference between installer preference and product specifications, and what matters for a Bendigo roof.

SolarQuotes’ 2026 Installer’s Choice survey asked 125 participating installers which brand they would put on their own roof. Aiko placed first with 28% of votes, Jinko second with 14%, and SunPower third with 11%. REC and Trina rounded out the top five.
This is an installer-preference survey, not a laboratory ranking or a guarantee for every panel. It does not imply that Unified Solar is endorsed by SolarQuotes or supplies every brand listed.
| Brand to research | Useful focus | What to confirm |
|---|---|---|
| Aiko | Back-contact residential cell technology. | Exact Australian model, dimensions, output and warranty issuer. |
| Jinko Solar | Tiger Neo N-type TOPCon residential range. | Residential module model, roof layout and supplied-model warranty. |
| SunPower | Premium panel ranges appearing in the survey. | Current Australian range, manufacturer and warranty terms for the quoted product. |
| REC | Alpha heterojunction range, including Pure-RX. | Model, temperature coefficient and whether any installer-dependent warranty conditions apply. |
| Trina Solar | Residential panel options appearing among the survey’s top five. | Exact module series, local support and product/performance cover. |
| Risen | A panel option already in our product guide. | Exact Australian module, efficiency, dimensions and warranty documents. |
Our current panel guide includes Risen, Jinko and REC. We confirm the available range and fit in your proposal; a survey position is not a reason to replace a suitable design.
Efficiency helps compare output per square metre. Module dimensions and usable roof area determine what actually fits.
Temperature coefficient and shade behaviour matter, alongside orientation, string design and installation quality.
Product cover addresses defects. Performance cover describes output retention under its terms. Check labour, transport, exclusions and who handles a claim.
For Bendigo and nearby towns, we assess seasonal shading, roof condition, summer temperatures and your daytime energy use. Ask for expected seasonal generation, a clear panel layout and the exact datasheet.
