The newly achieved result, independently confirmed and certified by TUV Rheinland of Germany's Shanghai Testing Centre, sets a record-high 17.2% conversion efficiency to date for the photo voltaic panels consisting of 60 regular industrial size (156x156sq.mm) multi-Si cells and using a single standard junction box.
JA Solar president Jian Xie said that topping 280W output power from multi-Si modules with 60 cells followed the company's recently announced progress in reaching a new efficiency record of multi-Si solar cells.
He said the milestone demonstrated the company's ability to reduce the cost of manufacturing solar cells and modules to meet the growing demand for high-performance solar power products.
JA Solar's chief operation officer, Yong Liu, said the output power of these record-setting solar modules could be further improved by fine tuning the company's module assembly process and encapsulation materials.
"At least another 5W increase is definitely achievable. That will add significant value for our down-stream customers in terms of increasing power generation and reducing installation cost," Liu said.
