Greentech Lead America: ET Solar Group announced it will launch its UL (1000V DC) certified PV modules at the upcoming PV America East 2013 conference and trade show.
The certification by Electrical Testing Laboratories (ETL), USA, applies to ET Solar 60-cell and 72- cell poly-crystalline modules.
With this certification, ET Solar modules can now be used in projects with system voltages up to 1000V DC rather than 600V DC, offering lower installation costs and improved system performance.
According to Dennis She, president and CEO of ET Solar, the certification from ETL endorses their modules designed for the US market.
