Abstract: Taking the construction of a rooftop photovoltaic（PV） power station as a research example, the power generation capacity of the station under the local climatic conditions was calculated theoretically, while the construction scheme of the rooftop PV station was put forward, including the type selection of the PV module, the selection of the inverter capacity and the corresponding connection method, the design of the PV array, etc. The proposed scheme not only has good environmental and social benefits, but also has certain economic benefits. This may serve as a reference for the construction of rooftop PV power stations.
