Photovoltaic power generation is a technology that uses the photovoltaic effect of the semiconductor interface to convert light energy directly into electrical energy. The key element of this technology is solar cells. After the solar cells are connected in series, they can be packaged to form a large-area solar cell module, and then a photovoltaic device can be formed by combining the power controller and other components. Photovoltaic power generation has the advantage of being less subject to geographic restrictions because it is sunny; the photovoltaic system also has the advantages of being safe, reliable, noise-free, low-pollution, energy-efficient, and without the need to consume fuel and erection of transmission lines to generate electricity on-site and for short construction periods.
Photovoltaic power generation is based on the principle of photovoltaic effect, using solar cells to convert solar energy directly into electrical energy. Regardless of whether it is used independently or connected to the grid, the photovoltaic power generation system is mainly composed of solar panels (components), controllers and inverters. They are mainly composed of electronic components and do not involve mechanical components. Therefore, photovoltaic power generation equipment Extremely refined, reliable and stable, long life, easy installation and maintenance. In theory, photovoltaic technology can be used in any application where power is needed, from spacecraft, down to home power, up to megawatts of power stations, to toys, and photovoltaic power is everywhere. The basic components of solar photovoltaic power generation are solar cells (sheets), monocrystalline silicon, polysilicon, amorphous silicon, and thin-film batteries. At present, the single crystal and polycrystalline batteries are the most used, and amorphous batteries are used in some small systems and calculators as auxiliary power sources.
The efficiency of domestic crystalline silicon cells is about 10 to 13%, and the efficiency of similar foreign products is about 12 to 14%. Solar panels made up of one or more solar cells are called photovoltaic modules. At present, photovoltaic power generation products are mainly used in three major areas: First, to provide power for non-electricity applications, mainly to provide electricity for residents living in areas without electricity, as well as microwave relay power, communication power, etc. Power supply and backup power supply; second, solar-powered daily-use electronic products, such as various types of solar chargers, solar Street Lights, and solar lawn lights; and third, grid-connected power generation, which has been widely implemented in developed countries. China's grid-connected power generation has not yet started, but part of the 2008 Beijing Olympic Games will be powered by solar power and wind power.
