Study on the photovoltaic (PV) system's application possibility

From summary of the solar photovoltaic project status, the cost and life returns of power generation systems and networks were calculated. The applied possibility of solar photovoltaic system and the promoted factors were technically and economically analyzed . By comparing solar photovoltaic with conventional power generation costs, investment period of the solar photovoltaic systems covered by the regional power grid was calculated, and the results demonstrated that the basic cost of the investment can be recovered. At the same time, the factors on the promotion of solar energy into the possibility were analyzed. According to geographical features of the analysis, it is reasonable to introduce independent photovoltaic power generation system in a field with the transmission distance greater than 50 kilometers.
