JA Solar 435 Wp modules - compact efficiency with strong performance


The 435 Wp solar modules from JA Solar combine powerful technology with a space-saving 54-cell format - ideal for roofs with limited space. As part of the Deep Blue 4.0 Pro series, they offer an impressive combination of efficiency, stability and durability. Thanks to high energy yields and strong mechanical resilience, they are an optimal solution for residential, commercial and smaller PV projects.

Technological highlights


The 435 Wp modules use 54 half cells in an 11-busbar design, resulting in improved current distribution and reduced power losses. With a module efficiency of up to 22.3 %, they are among the most efficient in their class. The robust glass surface, PID resistance and high mechanical load capacity (up to 5400 Pa snow load) ensure permanently stable performance - even under challenging environmental conditions. The annual degradation is limited to a maximum of 0.55 %, which ensures high yields in the long term.
