Photovoltaic power generation is a technology that uses the photovoltaic effect of a semiconductor interface to convert light energy directly into electrical energy. The key element of this technology is solar cells. After the solar cells are encapsulated and protected in series, a large area solar cell module can be formed, and a photovoltaic power generation device can be formed by combining the power controller and other components. Photovoltaic power generation has the advantage of being less restricted by geography because it is sunny; the photovoltaic system also has the advantages of being safe, reliable, noise-free, low-pollution, energy-efficient and requiring no fuel consumption, and the ability to install power lines to generate electricity on-site and have a short construction period.
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 system is mainly composed of solar panels (components)，solar mounting structures, 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.
