JA Solar begins production of 60-cell double-glass solar modules

China-based solar power products manufacturer JA Solar has commenced production of standard 60-cell double-glass modules.

The company has recently completed the reliability tests of modules to validate its compliance with the IEC61215 and IEC61730 standards, and secured TUV SUD certifications.

The multi-Si modules are covered with 2.5mm thick high strength tempered glass on both sides with a frameless design, to allow it withstand harsh environment without rapid degradation.

Underpinned by performance warranty of 30 years, the modules are designed in accordance with IEC standards for 1,500V systems, the company said.

Compared to regular PV modules, the new modules are expected to have less than 2.5% power degradation in the first year followed by a linear degradation rate of 0.5% annually.

Even after completion of performance warranty, the modules are expected to have 85% of its initial rated power, the company noted.
