With the state's policy support for solar power generation, whether it is photovoltaic power generation or solar thermal power generation, it has focused on people's attention. However, the cost of photovoltaic power generation remains high, and how to locate the on-grid tariff is still unknown. Academician Huang Qili said on the same day (8th) that as the price of solar energy decreases year by year and the price of thermal power rises steadily, the price will no longer be a bottleneck restricting solar power generation in a short period of time.
Huang Qili: "Photovoltaic electricity prices have dropped by about 6-8% every year in recent years, and the rate of conventional electricity prices and coal-fired power increases by 6%. The convergence of these two curves is in 2015 and 2016. It is expected that by 2020 Power generation and conventional electricity prices are balanced. That is to say, the difficulty of high cost in the initial stage of development can be solved within 5-10 years."
Zhao Zhongxian, an academician of the Chinese Academy of Sciences, said that the main source of renewable energy in China and the United States is hydropower. Both countries are committed to increasing the share of other renewable energy resources.
Zhao Zhongxian: "From now to 2020, wind energy, solar photovoltaic, solar thermal, traditional geothermal energy, and some biomass power generation will gradually expand in size and prepare for accelerated application."
Experts believe that in the next decade, China and the United States will become the world's two largest renewable energy application markets, and the two countries need to jointly address the challenges of large-scale application of renewable energy.
Zhao Zhongxian: "The effective combination of China and the United States' capabilities and experience will also make these technologies easier to promote on a global scale, enabling renewable energy resources to be effectively utilized in more countries."
China's solar power bottleneck will break into the main force of production and living electricity
According to China Voice's "National News Network" report, Huang Qili, an academician of the Chinese Academy of Engineering, said today that the "high cost" bottleneck of solar power generation in China will be broken, and it will fall to the conventional electricity price level within 5 to 10 years.
