In early May of 2018, Tongwei Solar independently developed a exceeding-420W high-efficiency imbricated module. Its 72-piece mode module has a maximum power output of 421.9W, breaking the world record of PERC module, and obtaining test verification by National Testing Center of Quality Supervision and Inspection for PV products in Chengdu.
The module’s conversion efficiency can reach 20.7%, which fully meets and greatly exceeds the technical threshold limit of “Technology Front Runner”. Thanks to the efforts of the Tongwei Solar R&D team, this high-efficiency imbricated module adopts high-efficiency imbricated cell and module technique that is completely self-developed and patented.
Due to the fact that its double-sided rate is greater than 75%, under normal reflected light, Tongwei Solar double-sided PERC imbricated module power can reach 460W. At the same time, the modules passed all the stability and reliability tests of the new IEC 61215 & IEC 61730 standards, and obtained the new standard certification of IEC 61215 & IEC 61730 for imbricated module issued by T?V NORD.
