Solar power generation system is a technology that uses the photovoltaic effect of the semiconductor interface to directly convert light energy into electrical energy. The key element of this technology is the solar cell. After the solar cells are connected in series, they can be packaged and protected to form a large-area solar cell module. Together with the power controller and other components, a photovoltaic power generation device is formed. The advantage of photovoltaic power generation is that it is less restricted by region, because the sun shines on the earth; photovoltaic system also has the advantages of safety, reliability, no noise, low pollution, no need to consume fuel and erect transmission lines to generate power and supply power on site, and the construction period is short.
Photovoltaic power generation is based on the principle of photovoltaic effect, using solar cells to directly convert solar energy into electrical energy. Whether it is used independently or connected to the grid for power generation, photovoltaic power generation systems are 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, stable, long life, easy to install and maintain. Theoretically speaking, photovoltaic power generation technology can be used in any occasion where power is needed, from spacecraft, down to household power sources, as large as megawatt power stations, as small as toys, and photovoltaic power sources are everywhere. The most basic components of solar photovoltaic power generation are solar cells (sheets), including monocrystalline silicon, polycrystalline silicon, amorphous silicon and thin-film batteries. As of June 2013, monocrystalline and polycrystalline batteries are still the most used, and amorphous batteries are used in some small systems and auxiliary power supplies for calculators.
