Dalian solar photovoltaic power generation system

Solar photovoltaic power generation system is the use of photovoltaic effect of semiconductor materials, solar cells, can be directly converted into a new generation of electric power system with solar radiation, operate independently and grid-connected two ways. Stand-alone PV system needs to have the battery as an energy storage device, mainly used in no power grid in remote areas and scattered population areas, the system cost is very high; in the regions with public power grid, photovoltaic power generation system connected to the power system network operation, save the battery, not only can reduce the cost, environmental performance and has higher the power generation efficiency and better
