The JA Solar JAM54D41-450/LB is a 450W full-black N-type monocrystalline panel with bifacial cells and double-glass construction. It reaches up to 22.5% module efficiency, so it fits more watts onto a given roof area than most older 400W-class panels. The N-type cells hold output better over the years than standard p-type cells, and the bifacial rear side can add yield on reflective or elevated mounts. The all-black double-glass build suits visible residential roofs where looks matter; buyers trade a little weight and glass fragility for durability and a clean finish.

The JA Solar JAM54D41-450/LB is a 450W full black solar panel with N-type bifacial cells. It is used in residential and commercial solar systems, including rooftop, hybrid and off-grid installations. The full black finish gives a uniform look on visible roofs.
The panel has a double-glass construction. The rear side captures reflected light, which can increase energy yield in the right installation conditions. It is rated for snow loads up to 5400 Pa and wind loads up to 2400 Pa.
It comes fitted with Stäubli MC4-EVO2 connectors, a 300 mm positive cable and a 400 mm negative cable. It is manufactured to IEC 61215, IEC 61730, IEC 62941, ISO 9001, ISO 14001 and ISO 45001 standards. A 30-year linear power output warranty applies.
