Classification Of Solar Power Generation Systems
Jun 01, 2018

Solar power generation systems are divided into off-grid generation systems, GRID-connected power generation systems and distributed generation systems:

1, off-grid power generation system is mainly composed of solar cell components, controllers, batteries, such as output power for the exchange of 220V or 110V, but also need to configure the inverter.

2. The grid-connected power generation system is the direct access to the public grid after the DC power generated by the solar module is converted to the AC power requirement by the grid-connected inverter. Grid-connected power generation system has centralized large-scale grid-connected power stations are generally state-level power plants, the main feature is that the power generation can be directly transported to the grid, the unified deployment of power grids to the user power. But this kind of power plant invests big, the construction period is long, occupies the area to be big, has not had the big development.

The decentralized small-scale grid-connected power generation system, especially the integrated PV power generation system, is the mainstream of grid-connected power generation because of its advantages such as small investment, fast construction, small footprint and strong policy support.

3, distributed generation system, also known as decentralized power generation or distributed energy supply, refers to the user site or near the site to configure a small photovoltaic power supply system to meet the needs of specific users, support the existing distribution network economic operation, or meet both requirements.
