Grid-connected solar photovoltaic power generation system is composed of PV cell arrays with grid-connected inverters, which directly feed electricity into the public grid through grid-connected inverters without battery storage.
Compared to off-grid solar PV systems, grid-connected solar PV systems eliminate the battery storage and release process, reducing energy consumption, saving space, and lowering configuration costs.
It is worth affirming that a large portion of grid-connected solar PV power systems are used in government grids and in cases of energy conservation in developed countries. Grid-connected solar power is the development direction of solar photovoltaic power generation and is a highly promising energy utilization technology for the 21st century.
Grid-connected photovoltaic power generation systems have centralized large-scale grid-connected photovoltaic power plants are generally national power stations, the main feature is to transmit the generated energy directly to the grid, the grid unified deployment of power supply to users. But this kind of power station investment, construction cycle is long, covers an area of large, and therefore there is not much development.
The decentralized small grid-connected PV system, especially the PV building integrated power generation system, is the mainstream of grid-connected PV power generation due to the advantages of small investment, fast construction, small footprint, and strong policy support.
