JA Solar pushes 60-cell multi-Si module to 280W



Major China-based PV manufacturer, JA Solar, has had TUV Rheinland verify its PERC cell technology modules have a record-high >17.2% conversion efficiency, producing a standard 60-cell module with a performance figure above 280W.

“This latest result of above 280W output power achieved from multi-Si modules with 60 cells is the continued effort of our R&D and follows JA Solar’s recently announced progress in reaching new efficiency record of multi-Si solar cells.” said Jian Xie, president of JA Solar. “This new milestone once again demonstrates JA Solar’s devotion in enabling cost-effectively manufacturing high-performance solar cells and modules to meet the growing demand for high-performance solar power products.”

The figures were recently confirmed and certified by TUV Rheinland at its Shanghai Testing Centre, according to JA Solar.

The 280W module figure has often been touted by PV manufacturers for monocrystalline solar cell-based modules in volume production, which have at least 1% to 2% conversion efficiency gain of multicrystalline-based modules.

“The output power of these record-setting solar modules we’ve just made can be further improved by fine tuning our module assembly process and encapsulation materials,” added Yong Liu, Chief Operation Officer of JA Solar. “At least another five watts increase is definitely achievable. That will add significant value for our down-stream customers in terms of increasing power generation and reducing installation cost.”

According to former NPD Solarbuzz, recently acquired by rival firm IHS, multicrystalline solar cell technology developments are expected to dominate conversion efficiencies for major tier 1 producers for at least the next five years.
