Photovoltaic power generation is based on the principle of the photovoltaic effect, and the light energy is directly converted into electrical energy using solar cells. Whether it is from the grid power generation or grid power generation, the photovoltaic power generation system consists mainly of the three parts of solar components, solar controllers, and inverters. The battery generation also requires the battery to store excess electrical energy to use lack of light or in the evening. They are mainly composed of electronic components, not involving mechanical components, so the photovoltaic power generation equipment is extremely refined, long and long-standing long, and easy to install and maintain.
Photovoltaic module: The photovoltaic battery assembly is connected in parallel according to the system requirements, and the solar energy is converted into electrical energy output under solar light irradiation, which is the core component of the solar photovoltaic system. Battery: Store the electric energy generated by the solar cell module, when the light is insufficient or evening, or the load demand is greater than the electric quantity sent by the solar cell assembly, it will be stored to meet the energy requirements of the load, it It is the energy storage component of the solar photovoltaic system. At present, the solar photovoltaic system is commonly used by lead-acid batteries. For higher requirements, a deep-discharged valve-free sealing lead-acid battery, a deep discharging, a lead-acid battery, and the like. Lake Water Floating Mount Systems: It specifies and controls the charge of the battery, and controls the energy output of the solar cell module and the battery to the load according to the load power supply requirements, which is the core control section of the entire system. With the development of the solar photovoltaic industry, the functionality of the controller is getting stronger, there is a trend of integration of traditional control parts, inverters, and monitoring system.
Inverter: In the solar photovoltaic power supply system, if an AC load is contained, the inverter device is used to convert the direct current generated by the solar cell module or the DC electrical charge released to the load required to load.
The basic working principle of the solar photovoltaic power supply system is to charge the electric energy generated by the solar battery assembly through the controller’s control or in the case where the load demand is controlled by the controller. The load is directly supplied to the load. If the sunshine is insufficient or at night, the DC load is powered by the battery under the control of the controller. For the photovoltaic system containing the AC load, it is necessary to increase the inverter to convert DC electrically converted to transition. The advantage of photovoltaic power generation is less dependent on the region, because the sun is grounded, the photovoltaic system also has a safe and reliable, noise, low pollution, no need to consume fuel and set up a transmission line to power generation and construction. The period is short.
