Evidence score

Not enough comparable data0% 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; Product warranty needed; Power warranty needed; Power temperature coefficient needed; First-year degradation needed; Weight / watt needed.

Not enough comparable data for a score. None of this panel's scored inputs has a documented, sourced value yet: module efficiency, product warranty, power warranty, power temperature coefficient, first-year degradation, weight / watt.

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.

Not documented, 0 points: Module efficiency, Product warranty, Power warranty, Power temperature coefficient, First-year degradation, Weight / watt.

Each input is compared with the best documented value among published solar panels, weight per watt within the same panel format · Method version 0.4
