Evidence score

31/10037% 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 temperature coefficient needed; First-year degradation needed; Weight / watt 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.

First-year degradationNot documented0.0 / 16.0

Not printed as a first-year degradation. The Qcells Q.PEAK DUO BLK ML-G10+ series 395-420 data sheet (DCA/DA, 2026-04 Rev01 NA) prints, in its Qcells Performance Warranty block, "At least 98 % of nominal power during first year" (a minimum warranted output, not a degradation figure) followed by a maximum annual degradation, and "Full warranties in accordance with the warranty terms of the Qcells sales organization of your respective country." Revised on 29 September 2026: The data sheet prints a minimum first-year output ("At least 98 % of nominal power during first year"), not a first-year degradation; the recorded 2 % was the difference from 100 %, a derived figure the research rules do not allow. The key is left unknown and the earlier value is kept below so the history stays.

Not documented. Undisclosed data scores 0.
