China Sunergy (CSUN), the Chinese module manufacturer awarded tier one module supplier status by Bloomberg New Energy Finance (BNEF) earlier this year, has announced that its latest 280W module is ready for commercial release.
The 280W mono-crystalline module consists of 60 solar PV cells. CSUN claims that under standard test conditions (STC), it can stably reach 280Wp, outperforming the standard 270W mono modules for generation capability.
In common with some of the other recently launched modules from CSUN, the new 280W mono features five busbars. According to CSUN, this “allows more efficient current collection and can also improve long term performance”. In other words, the module’s extra busbar will collect more current, improve reliability and reduce current loss due to tiny cracks in the module, CSUN claims. According to CSUN, its monocrystalline solar cells can reach 20% efficiency and its poly- can reach 18%, both in a commercial setting.
Currently the majority of commonly sold solar modules feature three busbars, although REC Group, headquartered in Europe with some manufacturing in Singapore, this year launched its TwinPeak half-cut modules, which have four.
The CSUN modules are expected to launch for the commercial and residential sectors in regions including Japan, according to Japanese press. CSUN founded a local subsidiary, CSUN Japan, earlier this year. The module maker was accredited with tier one status in March under the BNEF PV Module Maker Tiering System.
