Each part comes from the datasheet with a published rule; anything not stated scores zero.

How we rate solar panels

Output guaranteed at year 25
8.2 · 25%
What the panel promises to still produce after 25 Australian summers. It compounds every year.
Rule: Worked out from the datasheet's first-year and annual degradation: 84% scores 0, 92% scores 10.
Product warranty
2.5 · 25%
Covers defects in the panel itself. Twelve years is the floor; the best give 25 or more.
Rule: Years of product warranty: 10 scores 0, 30 scores 10.
Heat performance
8.6 · 20%
Panels lose output as they heat up, and roof panels often pass 65°C in summer.
Rule: Temperature coefficient of Pmax: -0.38%/°C scores 0, -0.24%/°C scores 10.
Efficiency
10.0 · 20%
More watts from each square metre, which matters most on small or broken-up roofs.
Rule: Highest module efficiency in the range: 20.5% scores 0, 25% scores 10.
Performance warranty length
10.0 · 10%
How long the output guarantee runs.
Rule: Years: 25 scores 0, 30 scores 10.

About the brand

Aiko solar panels

One of the most efficient panels you can put on an Australian roof, and installers' favourite two years running. Its local track record is short, so you're trusting the test results and the installer more than history.
