Evidence score

Research pending0% 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: Certificates evidence needed; Warranty term needed; Warranty energy disclosure evidence needed; Lifetime / capacity evidence needed; Cell model disclosure evidence needed.

Power stations · Output unconfirmed · Rated capacity

The warranty term and the lifetime energy are each scored against the best documented value for a power station: a value earns its share of that best, times the weight. A documented value always earns points; an undisclosed one earns 0.
