Li Chuangjun said that compared with the relatively quiet 10 years ago, the current social environment for photovoltaic development has undergone earth-shaking changes. In 2005, only 5 megawatts of new photovoltaic power generation were installed in China, accounting for only 0.36% of the global total. In 2005, the cumulative installed pv capacity of 70 megawatts was only 1.35% of the global total. In 2017, the newly installed capacity of the country reached 53G watts, accounting for 39% of the newly installed capacity of the national power supply, the world's largest increment for five consecutive years, accounting for half of the global increment. In 2017, China's cumulative installed pv power generation capacity reached 130G watts, ranking first in the world for three consecutive years, accounting for 32.4% of the global total. By the end of 2017, pv had generated about 256.5 billion kilowatt hours of electricity, saved more than 80 million tons of standard coal, and reduced emissions of carbon dioxide by 210 million tons, sulfur dioxide by 680,000 tons and nitrogen oxide by 592,000 tons.
Li chuangjun stressed that photovoltaic power generation in 2017 has also achieved both quality and quantity improvement and both light abandonment and light abandonment rate reduction. The form of power generation continues to be optimized, and the proportion of distributed photovoltaic installations continues to rise. The distribution of power generation continued to be optimized, and the new installed capacity shifted significantly to the east and central regions. The product structure has been continuously optimized, and the proportion of efficient components has been significantly increased. He introduced that technological progress has reduced the cost of photovoltaic power generation at an unexpected speed: in 2017, the prices of domestic polysilicon chips, cells and modules decreased by 26.1%, 25.7% and 33.3% year on year respectively, and the cost of photovoltaic power generation has been reduced to about 7 yuan/watt, and the cost of modules has been reduced to about 3 yuan/watt.
