JA Solar is a leading manufacturer and innovator of high-efficiency solar panels and renewable energy technology. They built up their brand through their high performance monocrystalline and polycrystalline 60 and 72 cell solar panels

JA Solar utilizes two primary solar cell technologies in their solar panels, PERC (P-Type) and N-Type. The cells are similar in design, however, the newer technology delivered by N-Type solar cells is more efficient, and are also not affected by Light Induced Degradation (LID).
