According to news from the Science and Technology Daily on the 13th, Li Xinjun, deputy director of the New Energy Division of the National Energy Administration, disclosed on the 12th that China's photovoltaic industry development situation in Beijing, with the support of policies and technological progress, the rapid growth of China's photovoltaic power generation industry, cost reduction and product replacement The speed is accelerating. From 2007 to 2017, the cumulative cost of photovoltaic power generation has decreased by approximately 90%. Photovoltaic power generation is expected to achieve parity within three to four years.

Li Chuangjun said that compared with the relatively deserted 10 years ago, the social environment for the development of photovoltaics has undergone earth-shaking changes. In 2005, only 5 megawatts of new photovoltaic power generation installed nationwide accounted for only 0.36% of the total global total. In 2005, the cumulative installed photovoltaic capacity was 70 megawatts, which was only 1.35% of the global total at the time. In 2017, the country’s newly installed capacity reached 53 Gwatts, which accounted for 39% of the country’s newly installed power supply. It was the largest in the world for five consecutive years and accounted for half of the global increase. In 2017, the cumulative installed capacity of photovoltaic power generation in China reached 130Gw. The total installed capacity in the three years was the first in the world, accounting for 32.4% of the global total. As of the end of 2017, cumulative photovoltaic power generated about 256.5 billion kwh, saving more than 80 million tons of standard coal, and accumulated emissions of carbon dioxide, sulfur dioxide and nitrogen oxide were 210 million tons, 680,000 tons and 592,000 tons, respectively.
