CCTV Interview with Ren Silong, Chairman of Nader:

After entering the 14th Five Year Plan, driven by the dual carbon policy, the new energy industry has entered a new cycle of rapid development, and the development momentum of Chinas photovoltaic market is good. The data shows that the cumulative installed capacity of photovoltaics in the first four months of this year was 48.31GW, a year-on-year increase of 186.2%. With the decline in silicon material prices, the supporting mechanism for photovoltaic storage is becoming increasingly sound, and demand is fully released. Experts predict that the total installed capacity of new photovoltaic units in China is expected to reach 140-150GW in 2023, a year-on-year increase of over 60%. Recently, Nader made a grand appearance at the 16th SNEC Photovoltaic Exhibition in 2023. That night, the CCTV-2 financial channel focused on the cutting-edge photovoltaic supporting new technologies at this years exhibition. As a leading enterprise in inverter supporting technology, Nader Chairman Ren Silong gave an interview to CCTV. He stated that the NDG3V specialized isolation switch for photovoltaic (PV) is the main component of the inverter, and it has independent protection technology and funct
