    ACOPOWER's own two-page HY-FL-55W data sheet ("High Efficiency Flexible Solar Modules HY-FL-55W", "55W Semi Flexible Solar Panel"), served from the file host of ACOPOWER's store (cdn.shopify.com, final address the same as the requested one, HTTP 200, application/pdf); Alternative Research retrieved the live original on October 29, 2026 at 19:29:17 UTC from an address it found in an earlier Internet Archive URL index, and Research copied it unchanged (SHA-256 rechecked). No current ACOPOWER page linking this exact file was established. Page 1 prints the Specification list recorded here; page 2 is an application picture and states that the controller, alligator clip and storage battery are not included. The text layer drops the ℃ and m² signs; those rows were read on the rendered page. It prints no date, revision, warranty term or certification mark. No reproduction limit is printed. Manufacturer claims, not independent tests.

    ACOPOWER's own Warranty & Return page, captured October 29, 2026: ACOPOWER's general warranty for its products by category (TESFRIDGE, solar panels, other products). It names no model and prints no policy date; a product's own document that prints a different warranty takes precedence on that product's record.

Evidence score

35/10068% 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; 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.
