The solar cells are packaged and protected in series to form a large-area solar cell module, and then combined with a power controller and other components to form a photovoltaic power generation device. The advantage of photovoltaic power generation is that it is less restricted by geographical area, because the sun shines on the earth; the photovoltaic system also has the advantages of safe and reliable, no noise, low pollution, no need to consume fuel and erect transmission lines to generate electricity on site and short construction period. Photovoltaic power generation uses solar cells to convert solar energy directly into electrical energy based on the principle of photovoltaic volts. Whether it is independent use or grid-connected power generation, photovoltaic power generation system is mainly composed of three parts: 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, stable, long life, easy installation and maintenance. In theory, photovoltaic power generation technology can be used in any occasion where power is required, from spacecraft, down to household power, to megawatt power stations, small to toys, and photovoltaic power everywhere. The most basic components of solar photovoltaic power generation are solar cells (sheets), such as monocrystalline silicon, polycrystalline silicon, amorphous silicon and thin film batteries. At present, single crystal and polycrystalline batteries are used the most, and amorphous batteries are used in some small systems and calculator auxiliary power supplies. The efficiency of domestic crystalline silicon cells is about 10 to 13%, and the efficiency of similar foreign products is about 18 to 23%. A solar panel consisting of one or more solar cells is referred to as a photovoltaic component. At present, photovoltaic power generation products are mainly used in three aspects: First, to provide power for non-electrical occasions, mainly to provide electricity for the living production of residents in the vast areas without electricity, microwave relay power, communication power, etc. In addition, some mobile Power supply and backup power; Second, solar energy daily electronic products, such as various types of solar chargers, solar street lights and solar lawn lights ; 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 is powered by solar power and wind power.
