Show series description

The JA Solar DEEPBLUE 4.0X / JAM72D40 555-580/MB series are modules designed for maximum yield in installations where long-term profitability matters. The use of n-type TOPCon cells helps limit typical losses associated with older technologies, stabilizing energy production over time. The bifacial double-glass construction allows for utilizing reflected light from the ground, genuinely increasing yield, especially on open land, light-covered roofs, and projects with appropriately selected module underlayments.

In practice, this series solves the issue of power drops at high temperatures thanks to its favorable temperature coefficient, while also minimizing the risk of micro-cracking and accelerated degradation, as glass-glass construction better protects the lamination. Furthermore, SMBB and dense packing improve current collection and resistance to partial shading, translating to more stable string performance.

This is an excellent choice for PV farms, large industrial rooftops, carports, and projects where high yields, longevity, and lower BOS costs per kWh are key.

Panels from the same series differ mainly in power output while having identical dimensions. Learn why →
