Evidence score

3/10026% documented

The Evidence score uses the priorities you choose. It counts published documents, such as certificates and warranty terms, and it compares a documented figure with the best documented figure of the same kind. It does not count owner reviews, and it is not a verdict on product quality or on how many people have reviewed it. A low score can mean little is documented, or that a documented figure is below the best of its kind. Undisclosed data scores 0.

Missing for this product: Module efficiency needed; Power warranty needed; Power temperature coefficient needed; First-year degradation needed.

Each input is scored against the best documented value for a solar panel, and weight per watt against the best in the panel’s own format. A documented value always earns points; an undisclosed one earns 0 and is listed as missing. Certificates and unsupported claims do not add points.

Weight / watt0.61 kg / 21 W2.1 / 5.0

0.02905 against 0.01227 kg per W, the lowest documented for a solar panel (calculated from maker figures): Go Power! 110-Watt Solar Flex™ Module

0.61 kg / 21 W. Lighter modules per watt carry less roof load. Panel format is not documented, so this is compared with every panel.
