AIKO Stellar 2N+78 770W Bifacial Dual-Glass N-Type ABC Solar Panel | AIKO-A770-GRH78DW

The AIKO Stellar 2N+78 770W Bifacial Solar Panel is a high-power commercial and utility-scale photovoltaic module built with advanced N-Type ABC cell technology. Designed for maximum energy generation and long-term reliability, the panel delivers 770W rated output power with a module efficiency of 24.0% under Standard Test Conditions.

Its bifacial dual-glass construction allows the module to generate electricity from both the front and rear sides. With a bifacial factor of 80% ±5%, the rear surface can capture reflected sunlight from suitable ground surfaces, potentially increasing total system energy yield compared with conventional monofacial modules.

The panel uses 156 high-performance cells in a 6 × 26 configuration and features 2.0mm + 2.0mm coated semi-tempered dual glass. This robust construction improves resistance to moisture, mechanical stress, micro-cracks and demanding environmental conditions. An anodized aluminium frame, IP68 junction box and MC4-compatible connectors further support dependable outdoor operation.

At Standard Test Conditions, the 770W model delivers an open-circuit voltage of 58.72V, maximum-power voltage of 48.77V, short-circuit current of 16.64A, and maximum-power current of 15.79A. The panel also has a positive power tolerance of 0 to +3%, helping ensure that actual module output is not below its rated power under specified test conditions.

The AIKO Stellar series is engineered for improved performance in partial shading and high-temperature environments. Its low power temperature coefficient of -0.26% per °C helps reduce output losses when module temperature rises, while the maximum system voltage of 1500V DC makes it suitable for large-scale solar installations.

The module is rated to withstand front mechanical loads of up to 5400Pa and rear loads of up to 2400Pa. It also meets IEC Class A fire-rating requirements and has been tested against 25mm hailstones travelling at 23m/s.

AIKO provides a 15-year product warranty and a 30-year linear performance warranty. The specified first-year degradation is no more than 1%, followed by annual degradation of no more than 0.35% from year 2 through year 30.
