JA unveils 510 W back-contact PV module with 25.5% efficiency

China-headquartered solar manufacturer JA made the Australian debut of its HyperGen Pro solar module and JA ESS 125 kW / 261 kWh liquid-cooled commercial and industrial (C&I) battery energy storage system at All Energy Australia 2026.

Designed for the Australian market, the HyperGen Pro features a 1,762 mm module format. The white variant delivers up to 510 W of power output at a maximum efficiency of 25.5%, while the all-black version offers up to 505 W at 25.3% efficiency.

The HyperGen Pro is based on JA ‘s Hycium n-type back-contact cell technology, which positions all electrodes on the rear of the cells, eliminating front-side grid lines. Combined with zero-busbar (0BB) interconnection technology and a full-screen design, the architecture increases the light-receiving area while providing a uniform appearance, particularly in the all-black version.

JA said the HyperGen Pro weighs 12% to 14% less than comparable dual-glass modules of the same format, reducing rooftop structural loads, improving heat dissipation and allowing single-person handling. The lighter design makes the module suitable for commercial and industrial buildings with limited roof load capacity.

The module has an HW4 hail-resistance rating and can reportedly withstand hailstones up to 40 mm in diameter, addressing reliability concerns in hail-prone regions such as Victoria, New South Wales and southeast Queensland.

A chemically etched, micro-textured glass surface converts specular reflection into diffuse reflection, reducing glare and addressing reflected-light concerns in urban environments.
