21 October, 2023 Various environmental factors influence the operational performance of a PV plant as a typical outdoor product. Long-term performance of photovoltaic (PV) systems is vital to continuing success in the market place. Recently, during the SNEC 2023 in Shanghai, DAS Solar has signed an outdoor test agreement with TÜV NORD to verify the electrical performance and reliability of N-type modules under 1500V DC voltage. This project officially connected to the power grid in the Hainan base of China Testing & Certification International Group (CTC).
