- Company introduction
-
※ TOPSUN's Features
- Founder was an ex-CEO of Symphony Energy(one of a leading pioneer in the solar industry)
- We are the only one in the world has capability to produce over 400Wp module
- Producing high efficiency module over 16%
※ By adopting 96 cell(over 400Wp)panel, you can have an advantage as follows
- Raw material cost for installation by about 5%
- Period for installation for about 1 week/MW
- System power loss mainly because the total length of the cables becomes much shorter
