First Solar advised that its thin-film Series 3 PV modules have met the standards and, therefore, listed by Underwriters Laboratories for UL1703 and ULC1703. The certification allows the modules to be used in PV systems up to 1,000V. Previously, the modules were UL listed as meeting the 1703 standards for use in PV systems up to 600V.
“First Solar is pleased that UL has validated the quality and safety of our modules, which are the first thin-film PV modules to receive this certification," said Tom Kuster, First Solar vice president of product management and system technology.
