| The thesis is focusing on analyses economic of household photovoltaic power generation system in Yunnan un-electricity regions. By applying the related theories and methods of economic research in engineering and project, the Net Present Value was compared between distribution networks and household PV system, installed cost and generating cost of household PV system were analyzed, sensitivity analysis of financial factors and functional factors were calculated.It presents three results. Household PV system should be chosen because of cost-effective when the initial investment of distribution networks was more than RMB￥1,000 or US＄3,100 per household. It is obviously cost lower when installation household PV system in un-electricity region, though the installed cost and generating cost of household PV system is cost higher than other major power source's. The economic performance of household PV system was impacted by the price of PV module, the price of electricity, the consumption of electricity, and the longest days of self-supply.It was a better supplying power chooses that installation household PV system in Yunnan or other un-electricity regions in China where residents live scattered and far from power grid, solar radiation with generally higher. |
