    AIKO's own two-page datasheet for the Stellar 2N+66 Dual-Glass Module 645W-680W (AIKO-A-GRH66Dw), version 202608 1.1_EN, linked from the "STELLAR 2N+66 Dual-Glass 645W-680W" product page on aikosolar.com and captured on October 30, 2026. The version is printed as "202608_1.1_EN" at the foot of page 2 (without the V of AIKO's other sheets; the file name reads V1_1). It prints the 8 module types AIKO-A645-GRH66Dw to AIKO-A680-GRH66Dw with STC and NOCT values and BNPI values, the mechanical data and the headline warranty terms. It names no sales region. Manufacturer claims, not independent tests.

Evidence score

82/100100% 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.

Every scored input has a recorded source for this product.

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.
