Types Of Solar Power Generation Systems

The solar power generation system is divided into the off net power generation system, the grid connected power generation system and the distributed generation system.
1, off grid power generation system is mainly composed of solar cell module, controller and battery. If output power is AC 220V or 110V, inverter is also needed.
2, grid connected power generation system is the direct current generated by solar modules, which is directly connected to the public power grid after converting the grid connected inverter into the AC power that meets the requirements of the municipal power grid. The grid connected power generation system has centralized large grid connected power stations, which are generally state-level power plants. The main characteristic is to directly transmit power to the power grid, and the power grid is uniformly allocated to the users. However, this kind of power station has large investment, long construction cycle and large area, which has not been greatly developed. The decentralized small grid connected power generation system, especially the photovoltaic building integrated power generation system, is the mainstream of grid connected generation because of its advantages such as small investment, fast construction, small footprint and strong policy support.
3, the distributed generation system, also known as distributed generation and distributed energy supply, refers to the user site or close to the photovoltaic power supply system of electric field configuration is small, to meet the specific needs of users, support the existing economic operation of distribution network, or at the same time to satisfy these two requirements.

The basic equipments of distributed photovoltaic system include photovoltaic cell module, photovoltaic array support, DC conflux box, DC distribution cabinet, grid connected inverter, AC power distribution cabinet, and other power supply system monitoring devices and environmental monitoring devices. The operation mode is in the solar radiation conditions, solar panels convert solar energy photovoltaic power generation system output power, through the DC bus box concentrated into the DC power distribution cabinet, inverter grid connected inverter by alternating current supply of building its own load, excess or insufficient power to regulate through grid connection.
