Analysis of the development trend of solar photovoltaic power generation in the future

With the advancement of science and technology, people have gradually understood the use of solar energy. The construction cost of solar photovoltaic power generation is decreasing year by year, and photovoltaic power generation will enter the homes of ordinary people in the next ten years. At present, the technological progress of the photovoltaic industry is very fast, and the cost of polysilicon, silicon wafers, cells, battery modules and other links is decreasing year by year. Although more than 95% of solar photovoltaic cells produced in China are currently exported to Europe and the United States, their prices have dropped from US$4/W in 2008 to US$2/W at present. In addition, in the construction of photovoltaic power plants, the cost of grid-connected inverter equipment and construction and installation is also decreasing. The consensus forecast in the solar street light industry is that by 2020, the construction cost of photovoltaic power plants will drop to $1/W, of which the cost of photovoltaic cell components will drop to $0.6/W. This means that the on-grid price of large-scale ground photovoltaic power plants can be reduced to 0.3~0.4 yuan/watt, which will be the same as the on-grid price of thermal power generation. Various supporting policies for starting the solar photovoltaic power generation market in China are being formulated. In Germany, Spain and other countries where solar photovoltaic power generation has been applied earlier, it has become very convenient for residents to install solar power plants on their roofs. As long as they fill out an application form at the management department, professional institutions will provide services for bank loans, installation and Internet access. In 2020, when the on-grid price of solar photovoltaic power generation is at the same level as the price of traditional energy, the domestic solar photovoltaic power generation construction will definitely develop rapidly. I believe that by then, Chinese residents can also install rooftop solar photovoltaic power stations as easily as installing telephones. .
