Product Specifications

Product Details

The JA Solar DeepBlue 4.0 625W N-Type Bifacial Double Glass Solar Panel is a high-performance solar module designed for high energy generation, improved efficiency, and reliable long-term operation. The JAM78D40-625/MB uses Mono-16BB cells and delivers a maximum power output of 625W with module efficiency of up to 22.4%.

Its N-Type technology provides very low LID, while the bifacial double-glass construction enables the panel to generate additional energy from the rear side. With a bifaciality of 80 ± 10%, actual rear-side energy gain depends on installation conditions, mounting configuration, and surrounding surface reflectivity.

The module features 2.0mm front and 2.0mm rear glass, an IP68-rated junction box with three diodes, and a robust mechanical load capacity of 5400 Pa on the front and 2400 Pa on the rear. Its improved weak-illumination response and temperature coefficient help maintain stable energy generation across different operating conditions.

The JA Solar 625W panel comes with a 12-year product warranty and 30-year linear power output warranty, with 1% first-year degradation and 0.4% annual degradation thereafter. It is well suited for commercial, industrial, utility-scale, and distributed solar installations.
