JA Solar JAM72D42 LB 615-640W Solar Panel Series

JAM72D42 LB upgrades to JA Solar's 42-series deep cell architecture within the 72-cell format — 615–640W — approximately 40–45W more per module than the earlier JAM72D40 at the same physical footprint. This power increase directly reduces module count and BOS cost for a given system kWp.

N-type TOPCon bifacial glass-glass construction suits ground mount projects in high-albedo environments — sandy substrate, white gravel hardstand or light concrete — where rear-side gain can be modelled and included in yield projections. A higher bifacial factor than mono PERC equivalents means less sensitivity to the choice of tracker vs fixed-tilt mounting.

OmniSol matches JAM72D42 LB with 1500 V C-steel ground mount racking, 6 mm² PV cable and combiner boxes for 8–24 string configurations. Project-specific pile design and row spacing calculations are available as part of the OmniSol ground mount engineering package.
