    Go Power!'s own datasheet PDF, linked as the Spec Sheet from the product page and served from Go Power!'s product-document bucket on s3-us-west-2.amazonaws.com/catsy.549, captured on September 25, 2026. The sheet prints no revision or date. Its STC note prints "Irradiance: 1900 W/m2" rather than the usual 1000 W/m2; the figures are recorded as printed with that note quoted.

Evidence score

15/10037% 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; Product warranty 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.

Printed as "Power coefficient 31.3 °F / –0.38% °C" (a Fahrenheit figure followed by the percentage per degree Celsius); the percentage per °C is recorded, captured on September 25, 2026.
