FAQS about Yushu Industrial and Commercial Photovoltaic Support Cost

Will PV power the future of China's electricity system?

According to the report of the International Energy Agency (IEA), by 2040, the electricity generated from PV systems in China will account for 13.2% in the stated policies scenario and 23.4% in the sustainable development scenario. As a result, PV will play a more important role in the future electricity system in China.

Is small rooftop photovoltaic a good investment in China?

The results show that: For small rooftop photovoltaic in China, first of all, under the existing subsidy price and cost, its investment payback period is short and the risk is low. Secondly, the average internal rate of return is more than 10%, and the levelized cost of electricity is 0.2727–0.5573CNY/kWh, so the economic performance is good.
