JA Solar JAM54S30/GR 415W Black Frame

The JA Solar JAM54S30/GR series (400–425W) is a premium monocrystalline PERC module engineered for high performance, reliability, and elegant aesthetics. Designed with a black frame and optimized for rooftop applications, this module combines modern appearance with advanced cell technology to maximize energy yield in limited roof space. 

Thanks to half-cell architecture, the module reduces internal power loss, improves shade tolerance, and delivers higher output under real operating conditions. This makes the JAM54S30/GR particularly suitable for residential and small commercial PV systems where performance per square meter is crucial. 

The module is built to withstand demanding environmental conditions, offering strong mechanical load resistance and long-term durability. Its optimized cable lengths (1100 mm + 800 mm) simplify installation and improve layout flexibility on rooftops. 

With power classes ranging from 400W to 425W, installers can select the ideal output for their system design while benefiting from JA Solar’s proven manufacturing quality and long-term reliability.
