Photovoltaic power generation is a technique that utilizes the photovoltage effect of the semiconductor interface to convert light energy directly into electrical energy. The key component of this technology is solar cells. Solar cells through the series after the package protection can form a large area of the solar cell components, and then with the power controller and other components to form a photovoltaic power generation device. PV power generation is less limited by geographical constraints, because the sun shines on the earth; PV system also has a safe, reliable, no noise, low pollution, no need to consume fuel and erection of transmission lines can be local power supply and short construction cycle advantages.
Photovoltaic power generation is based on the principle of photovoltaic effect, the use of solar cells can be directly converted into solar energy. Whether it is used independently or grid-connected, the PV system consists mainly of solar panels (components), controllers and inverters, which are mainly composed of electronic components and do not involve mechanical parts. Therefore, photovoltaic power generation equipment Extremely refined, reliable and stable long life, easy installation and maintenance. In theory, photovoltaic power generation technology can be used in any need for power occasions, up to the spacecraft, down to home power, large to megawatt-class power station, small to toys, photovoltaic power everywhere. Solar photovoltaic power generation is the most basic components of solar cells (film), monocrystalline silicon, polysilicon, amorphous silicon and thin film batteries. At present, the largest single crystal and polycrystalline batteries, amorphous batteries for some small systems and computer auxiliary power and so on.
