Description

JA Solar DeepBlue 4.0 Pro JAM54D40-455/LB 455W N-Type Bifacial Double Glass Solar Panel

The JA Solar JAM54D40 455W (JAM54D40-455/LB) is an n-type bifacial double glass solar panel from the JA Solar DeepBlue 4.0 Pro JAM54D40 LB series, built for residential and commercial rooftops. It delivers 455W of front-side power at 22.8% module efficiency from 108 (6 × 18) n-type mono half-cells, with 1.6 mm front glass and 1.6 mm back glass.

Inside, the JA Solar JAM54D40 455W uses JA Solar n-type Bycium+ 16BB multi-busbar (MBB) half-cell technology, which the datasheet rates at up to 26% cell conversion efficiency. The datasheet highlights higher power generation with a better LCOE, very low LID for an n-type module, a better temperature coefficient, and a better low-irradiance response.

JA Solar JAM54D40 455W High-Efficiency Performance
