Solar power generation Solar power generation is divided into photothermal power generation and photovoltaic power generation. Solar power generation usually refers to solar photovoltaic power generation, or photovoltaic power generation for short. Photovoltaic power generation is a technology that utilizes the photovoltaic effect at the semiconductor interface to directly convert light energy into electrical energy. The key component of this technology is the solar cell. Solar cells can be connected in series and then encapsulated and protected to form a large-area solar cell module. Together with components such as a power controller, a photovoltaic power generation device can be formed. Compared with conventional power generation technology, photovoltaic power generation has no intermediate conversion process, the power generation form is simple, the power generation process does not consume resources, does not emit greenhouse gases, exhaust gases and waste water, has no mechanical rotating parts, does not exist mechanical wear, and has no
Noise, power generation without cooling water. Power generation equipment can be installed in waterless desert areas, or on rooftops and walls in cities. It does not occupy a separate area, has a modular structure, can be arbitrarily large or small, and can be operated, maintained and managed. Simple, unattended, and extremely low maintenance costs. In particular, solar energy is inexhaustible and the content of silicon resources required for photovoltaic cell manufacturing in the earth's crust is as high as
1. Application
Photovoltaic power generation products are mainly used in three major areas
First, grid-connected power generation, which has been widely promoted and implemented in developed countries.
Second, it is solar daily electronic products, such as various types of solar chargers, solar street lights and solar lawn lamps, etc.
Third, it is to provide power for occasions without electricity, and to provide life and production for the majority of residents in areas without electricity. Electricity, as well as microwave relay power supply,
communication power supply, etc. In addition, it also includes some mobile power supplies and backup power supplies
2. Development advantages
China is located in the northern hemisphere, with long distances from north to south and east to west. above kilometers. China's vast land is rich in solar energy resources. The annual average daily radiation in most areas is above kilowatt-hours per square meter, and the highest daily radiation in Tibet is
kilowatt-hours per square meter. Annual sunshine hours are greater than hours. Compared with other countries at the same latitude, it is similar to the United States and much superior to Europe and Japan, so it has huge development potential. China's theoretical solar energy resource reserves amount to 100 million tons of standard coal per year.
3. Prospect Planning
According to the "Medium and Long-term Development Plan for Renewable Energy", by 2020, China will strive to achieve a solar power installed capacity of
. (million kilowatts), and by the year it will reach ( million kilowatts). It is expected that by 2020, China's renewable energy power installed capacity will account for % of the country's power installed capacity, of which photovoltaic power generation installed capacity will account for %. It is expected that before 2020, the compound growth rate of China's solar installed capacity will be as high as over 30%.
