AbstractThe photovoltaic (PV) system in a building is being actively promoted; however, they have a high initial investment cost and take a long time to make money back. To solve this challenge, this study aimed to propose an integrated approach to evaluating how feed-in tariffs (FiT) affect the life cycle economic performance of PV systems in educational facilities, in which the impact of China's zonal FiT policy was investigated in various ways. The integrated approach consists of three steps: (i) data collection; (ii) technical analysis of PV systems by considering shading effects; and (iii) economic analysis of PV systems by considering a government financial supporting policy. The followings are main findings. If the self-consumed utilization plan (SC plan) and the grid-connected utilization plan (GC plan) could be mixed together and used as a single utilization plan, net present value at year 25 (NPV25), saving-to-investment ratio at year 25 (SIR25) and break-even point (BEP) were found to be 1423.03 USD/kW, 2.63, and 6.40 years, respectively. This study could be a promising approach for the managers of educational facilities to evaluate in advance whether PV systems would be feasible for their buildings from a long-term perspective with government policy (e.g., FiT upwards).
