Evidence score

27/10052% 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: 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.

Module efficiency23 %23.5 / 26.0

23 of 25.5 %, the best documented for a solar panel (printed by the maker): AIKO Comet 3N72 AIKO-A690-MDE72Mw 690W Mono-Glass Module

The manual prints Conversion Rate "23%"; the page prints "Efficiency: 23% Conversion Rate". Whether this is a cell or module figure is not stated.

Weight / watt9.68 kg / 400 W3.3 / 5.0

0.02425 kg per W is the less favorable figure the maker's documents print, and it is scored because they disagree; it never sets or raises the bar. The bar is 0.016 kg per W, the lowest documented for a portable solar panel, calculated from maker figures: BougeRV 50W Fiberglass Flexible Portable Solar Panel

9.7 kg / 400 W. Lighter modules per watt carry less roof load.

The maker's documents disagree; the less favorable printed figure, 0.02425 kg per W, is scored. Warning: ABOK documents disagree
