Solar power system divided into off-grid and grid-connected power systems: photovoltaic power generation system

1, off-grid systems. Composed primarily of solar module, controller, batteries, to power the AC load, you also need to configure the AC inverter.

2, grid-connected generation system is produced by the solar panels convert DC electricity after grid-connected inverter when AC mains power requirements have been met is directly connected to the public electricity grid. Grid-connected generation system centralized in large grid-connected power plant are generally State-level power plant, the main characteristic is the power straight into the grid, powered by the grid allocation to users. But this power plant investment and long construction period, covers an area of, and development is difficult. Grid-connected and decentralized small system, especially in building integrated PV system, due to low investment, building fast, small footprint, policy support and other benefits, is the mainstream of grid-connected power generation.
