Product Description

JA Solar JAM72D10 390-410W Bifacial Double Glass Half Cell Solar Panel

The JA Solar JAM72D10 390-410W Bifacial Double Glass Solar Module is a high-performance photovoltaic panel designed for utility-scale solar projects, commercial PV systems, and distributed energy applications. Built with MBB (Multi Busbar) mono PERC cells and half-cell technology, this module delivers higher energy output, improved reliability, and enhanced power generation performance under different environmental conditions.

Featuring a double glass bifacial structure, the JAM72D10 series can generate electricity from both the front and rear sides of the module by capturing reflected sunlight. Compared with traditional single-sided modules, the bifacial design improves overall energy yield, especially when installed on reflective surfaces such as white roofs, concrete areas, and ground-mounted solar farms.

With a power range of 390W to 410W, module efficiency up to 20.0%, and excellent temperature performance, JA Solar JAM72D10 solar panels provide stable long-term operation in demanding environments. The glass-glass structure enhances mechanical strength, moisture resistance, and durability, making it suitable for projects requiring high reliability and extended service life.
