Design and Benefits Analysis of Building Integrated Photovoltaic Project
Abstract
A public building integrated photovoltaic project in Yinchuan is introduced in this paper. In the BIPV project the polycrystalline cells are installed on the roof, which provide lighting electricity for the building. With the help of building simulation software, the available vacant area is analyzed. The total installed capacity is 100 KW; the annual generation capacity of the photovoltaic project is 115081 KWh. It has obvious environmental benefits to utilize renewable energy. In this project utilization of PV system can replace 38.21 tons of standard coal; reduce 102.65 tons of carbon dioxide emissions, 0.77 tons of sulfur dioxide, 0.06 tons of nitrogen oxide and 0.39 tons of dust. However compared with the traditional municipal power supply, the cost effectiveness ratio of the PV power supply system is 0.23 USD/KWh. According to the technical and economic analysis, in order to promote the wide application of photovoltaic technology, it needs certain policies and financial allowance.
