ET Solar Group Corp. says it has developed PV modules that have been tested to Underwriters Laboratories' standards (1,000 V DC) and granted certification by Electrical Testing Laboratories Inc. The company plans to formally launch the products at the upcoming PV America East conference in February.
The new 1,000 V DC certification applies to ET Solar 60-cell and 72-cell polycrystalline modules. With this certification, ET Solar modules can now be used in projects with system voltages up to 1,000 VÂ DC rather than 600 V DC, offering lower installation costs and improved system performance, according to the company.
