Trina Solar Ltd. says its TSM-PE05A and TS-PE14A polycrystalline modules have received UL1500V certification from Underwriters Laboratories (UL).
The UL1500V award certifies that the modules are allowed to be used in PV systems with a maximum system voltage of 1500 V, significantly higher than the existing 1000 V of most modules on the market, says Trina Solar.
Furthermore, the company says, the certification demonstrates that the modules produced meet higher technical standards and quality requirements. The higher system voltage modules allow customers to design PV systems with a longer string length, significantly reduce the number of balance-of-system (BOS) components and reduce the cost per unit of power of BOS.
