Designed for the US market, ET Solar has had modules tested to UL (1000V DC) by the US-based Electrical Testing Laboratories Inc.
The new certification relates to ET Solar’s 60-cell and 72- cell poly-crystalline modules, which can be used in PV projects employing system voltages up to 1000V DC rather than 600V DC that are claimed to lower installation costs and improve overall system performance.
