Product overview

The AIKO-A770-GRH78Dw is a Stellar 2N+78 N-type ABC dual-glass module rated 770Wp at STC, with 24.0% module efficiency. It has 156 cells. The cited datasheet bifacial factor is 80%±5%. The 770W rating is not continuous field output.

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.

Source notes

STC values match the 770W column of the Stellar 2N+78 202601 V4.1 reference. The official PDF URL returned 404 when checked, so confirm the nameplate on the supplied module.

Warranty and degradation

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

SREDA

The SREDA module list includes AIKO-A770-GRH78Dw at 770Wp, laboratory BUET Ref# 101770 dated 2026-09-24, reference 348/327, against the same BDS IEC 61215 and 61730 set. That does not approve a customer's whole project.

Installation

String 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.
