Photovoltaic power generation is the new energy business line of Kuangda Technology. It uses the photovoltaic effect at semiconductor interfaces to convert light directly into electricity, mainly comprising solar panels (modules), controllers and inverters, with key components made of electronic parts. The working principle is that the direct current generated by solar modules is converted by inverters into alternating current meeting grid requirements and then fed directly into the public grid, which distributes it to users.

Total installed capacity 200 MW; main operating regions include Fuyun, Wenquan and Ruoqiang in Xinjiang, Yulin in Shaanxi, Tonghai in Yunnan, Heze in Shandong and Xuanhua in Hebei; composed of solar panels (modules), controllers and inverters; generated alternating current is fed into the public grid for unified dispatch
