The working principle of photovoltaic power generation
Photovoltaic is a technology that uses the solar effect of the semiconductor interface to directly convert light energy into electricity. The key component of this technology is solar cells. Solar cells can be packaged and protected in series to form a large area of solar cell components, and then with power controllers and other components to form a photovoltaic power generation device.
The advantage of photovoltaic power generation is that it is less limited by the region, because the sun shines on the earth; The PV system also has the advantages of safety and reliability, no noise, low pollution, on-site power generation and power supply without the need to consume fuel and set up transmission lines, and a short construction cycle.
PV power generation is based on the principle of photovolt effect, using solar cells to convert sunlight directly into electrical energy. Whether it is used independently or connected, the photovoltaic power generation system mainly consists 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 is extremely refined. Reliable and stable life long, easy to install and maintain. In theory, photovoltaic technology can be used in any field that requires power supply.
Together, up to spacecraft, down to home power supply, up to megawatt power station, down to toys, photovoltaic power supply everywhere. The most basic components of solar photovoltaic power generation are solar cells(tablets), such as monocrystalline Silicon, polysilicon, amorphous silicon, and thin film cells. At present, single crystal and polycrystalline batteries are the most used, and amorphous batteries are used in some minor systems and calculator auxiliary power supplies.
