The photovoltaic greenhouse is the greenhouse shed which integrates the solar photovoltaic power generation, intelligent temperature control and modern high-tech plantation. It adopts the steel skeleton and the solar photovoltaic modules to guarantee the illumination requirements of photovoltaic power generation component and the daylighting requirement of the whole greenhouse shed, directly supports the normal operation of the agricultural equipment of greenhouse, and drives the water resource irrigation. Meanwhile, it solves the heating of greenhouse shed in winter, improves the shed temperature and promotes the rapid growth of crop. 

The photovoltaic greenhouse project combines the sightseeing agriculture and the facility horticulture. It is the innovative agricultural industry of integrating the photovoltaic power generation, agricultural sightseeing, agricultural crops, agricultural technology, landscape architecture and cultural development. 

As a kind of new-type power generation system which can utilize the photovoltaic effect of solar battery's semiconductor materials to convert the solar radiation into electric energy, the solar photovoltaic power generation system has the 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. The photovoltaic panel components could be used on the surface of and at top of greenhouse, and are used as part of the window, skylight or shading devices. In the area with public supply grid, the photovoltaic power generation system connects with the electric power grid for the grid-connected operation, and the storage battery is saved, which could not only reduce the construction cost greatly, could also own higher generating efficiency and better environmental protection performance.
