JA Solar 550W Bifacial Double Glass Solar Panel

JA Solar 550W Bifacial Double Glass Solar Panel

The JA Solar JAM72D30-550/MB is a 550W bifacial double-glass solar panel designed to produce electricity from light reaching both the front and rear surfaces. Its 11-busbar mono PERC half-cell construction supports dependable energy production, reduced shading losses and strong mechanical durability for residential, agricultural and commercial solar installations.

Customers can purchase one panel or select a complete factory pallet containing 36 panels. A full pallet provides 19.8kWp of combined rated solar capacity and offers a lower effective price per panel than purchasing 36 individual units.

Installation and Compatibility

Solar panels must be installed using compatible mounting equipment, electrical protection and an inverter design that accommodates the panel voltage and current. String length, cold-weather voltage, cable sizing, roof loading and structural suitability must be verified by a qualified solar installer before installation.
