As a kind of new-type power generation system which can utilize the photovoltaic effect of solar battery's semiconductor materials to directly convert the solar radiation into electric energy, the solar photovoltaic power generation system has the following two ways, namely, independent operation and grid-connected operation. The independently operated photovoltaic power generation system shall install storage battery as the energy storage device, which is mainly used in the remote areas and densely scattered areas without electric grid, therefore, the whole system needs high costs; However, the photovoltaic power generation system can realize the grid-connected operation with the power grid in the public power grid existence areas, as a result, the storage battery is saved and the high costs are reduced by a large margin, what's more, which can realize the higher power generation efficiency and better environmental protection performance.
