Abstract:

This paper mainly analyses a BAPV system of 3kWp and a BIPV system of 10 kWp in Shanghai, China. Net present value (NPV) and the payback time (Pd) as the parameters to determine the profitability of the system based on some actual measured data. As there are two subsidy policies in China, including the initial investment subsidy and PV electricity tariff subsidy. The variations of NPV and Pd with the initial investment subsidy and PV electricity tariff subsidy are researched. Analysis results indicate both the systems have a good economic benefit. Since the manufacturing, utilization and recycling periods of PV systems can lead to negative impacts on the environment. Environmental impacts by both the systems are also evaluated in this paper by the energy payback time (EPBT) and greenhouse-gas payback time (GPBT). Results show both the systems have a good environmental benefit, PV technology and PV system are sustainable.
