Show series description

The Sharp GSD8K66H series [710-740W] are modules designed to maximize energy output from every square meter – particularly in situations where high power output from a single panel and rapid string construction are crucial. The use of bifacial construction in a glass-glass configuration allows for energy recovery from both sides, significantly improving production in installations on reflective surfaces, flat roofs, and ground-mounted systems. The HJT technology with half-cut cells helps minimize losses and maintain stable performance under varying conditions, while also enhancing long-term material fatigue resistance. Another key feature is low sensitivity to high temperatures, allowing the module to lose less power on hot days compared to many popular solutions. This is further enhanced by high environmental resistance and a robust design for commercial projects. This makes it a good choice for PV farms, large industrial rooftops, and installations where high output and predictable performance are the priority.

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