This page presents the AIKO-A650-GRH66Dw as a Stellar 2N+66 N-type ABC dual-glass module, 650Wp at STC and 24.1% module efficiency. It has 132 cells and an 80%±5% bifacial factor on the 2026 2N+66 sheet. The price list's 1N+66 electrical set is a different revision.
An STC watt rating is not daily energy. Output depends on irradiance, temperature, orientation, shade, mounting and inverter design. A bifacial factor does not guarantee extra kilowatt-hours.

Datasheet: 15-year product warranty and 30-year performance warranty, subject to AIKO terms. SOLAR24 support follows the site warranty policy. The datasheets state a 15-year product warranty and a 30-year performance warranty, with first-year degradation ≤1% and ≤0.35% each year after that. That is not a guarantee of daily output. Warranty policy
AIKO-A650-GRH66Dw was not in the SREDA module-list extract checked on 18 October 2026. A665 and A770 were. Absence from that extract is not final proof it is unlisted. Check the register again before claiming approval.
Official SREDA module listString design must keep cold Voc under the 1500V system limit and leave inverter current margin above Isc. Maximum series fuse rating is 30A. Follow the datasheet clamp zones for this dual-glass weight. Site installation is not included unless agreed separately.
