Tsinghua sunshine solar pv installed 2050 maintenance proportion will reach nearly sixty percent

Editor's note: recently, released a report, according to a report in 2050, photovoltaic power generation will become China's first big power, photovoltaic power generation total scale of 5 billion kilowatts, accounted for 59% of the national total.

recently, '2050 China pv development outlook report at the 25th UN climate conference & other; Throughout China Angle &; Renewable energy to promote energy revolution achievement exchange issued at the meeting. The report by the National Development and Reform Commission energy research institute, longji and shanxi coal chemical group to complete together, solar portal, by renewable energy is the world's first private technology enterprises as an important participant of national clean energy technology outlook report.

according to the report, technology continues to progress is the biggest driver of photovoltaic power generation cost reduction, and the rapid decline in photovoltaic power generation cost will lay foundation for the high pv deployment. In the pv module cost reductions and conversion efficiency continued ascension leads, the photovoltaic power station in 2035 and 2050 unit investment is expected to be lower than the current level respectively 37% and 53%; By 2025, photovoltaic (pv) when the new power generating cost ( The tax and the reasonable yield) Is expected to be lower than 0. 3 yuan/kWh. Cost advantage in the later will be increasingly apparent, new photovoltaic power generation cost by 2035 and 2050 will drop to around zero. 2 yuan/kWh and 0. 13 yuan/kWh.

according to the report, in the case of a falling cost of photovoltaic power generation will become one of the most market competitive power generation technology. By 2050, photovoltaic power generation will become China's first big power, photovoltaic power generation total scale of 5 billion kilowatts, accounted for 59% of the national total installed, annual output of about 6 trillion KWH, accounted for 39% of the whole society power consumption.

at the same time, in the long run, photovoltaic power grid, the energy body of coal capacity will gradually decline. Reported that due to the growth of China's electricity, solar panels, installed capacity of coal will remain structural growth, 2025 - Up to 1. 2 billion kw, 2030 capacity then began to decline gradually, to 2050, the coal capacity will drop to 6 - 700 million kw. With the rapid development of new energy, coal and electricity from the power subject to capacity of the main body, and gradually shift from the subject position to the foundation status.

the rapid development of photovoltaic industry will play a positive role in macroeconomic development. Daniel li longji stake President, said: & other; Photovoltaic industry production can directly drive the silicon, batteries, electronic components, glass, and other related industries, and at the same time has significant stimulating effect on the upstream industry. ” Is expected that by 2050, photovoltaic industry with a total investment of 1 trillion yuan, realize the added value of 1. 89 trillion yuan, create 5 million direct and indirect employment.

, according to the report of photovoltaic power generation accounted, solar energy, will accept put forward higher requirement to the power grid, in this case, supporting the demand of energy storage is also rising. Adjust the main chemical energy storage technology will be days, provide strong support for photovoltaic power generation the high proportion of applications.

reported that at present, investments in the lithium ion battery energy storage system price is about 1500 yuan/kWh, storage charge and discharge kWh cost is about 0. About 6 yuan/kWh, solar energy, the future still have a large decline in space. To 2035 and 2050, represented by the lithium battery is expected to chemical energy storage in such aspects as life, safety, reliability, investment cost will be decreased by more than 60% and 75%, respectively, than the current level. Through power battery arrangement in use can also further reduce the system cost of storage, more competitive.

the report also highlights the pumping energy storage, hydrogen and other technology in the future will play an important role in enhance stability of photovoltaic power generation. Pumped storage power station of low cost, is currently the most economical form of large-scale energy storage, but restricted by geographical conditions. Under the long period, large capacity storage requirements, the hydrogen more advantages than a pumping energy storage.

Daniel li said: & other; Now is in of the historical turning point of photovoltaic power generation to achieve parity with Internet access, it is necessary to reposition photovoltaic energy transformation and respond to climate change in the role and significance. Both mitigation action to combat climate change and achieve the sustainable development of the global long-term vision, the backbone of the photovoltaic power generation will be important. ”
