The dual-glazed Vertex S+ 505W module was launched in January and began mass production in February at the company’s factory in Changzhou, China. The module has a maximum output power of 505 W and an efficiency of 22.7%. The dual glass design of the module also increases scratch, crack and impact resistance and provides resistance to salt spray, acids, alkalis, high temperature and humidity.
In addition, the module has a degradation rate of 1% in the first year and 0.4% per year. It can also deliver 8.6% more power than p-type modules. In addition, Trina Solar said the module is compatible with other balance of system (BOS) components and mainstream inverters, optimizers and mounting systems on the market.
In addition to this module, Trina Solar has recently improved the power conversion efficiency of its TOPCon Vertex N series modules, with the Vertex N 720W+ modules now boasting 23.2% efficiency.
