【 摘 要 】

Building integrated photovoltaic (BIPV) is an important application of solar cells. In this paper, the experiments were conducted to test the performance of photovoltaic panels installed in buildings. The experiments were carried out in Chengdu, Southwest China which located in climate zone of hot summer and cold winter. The real-time power generation, the simultaneous generation of heat and the impact on indoor lighting are important factors for building energy consumption. Two identical rooms were built up as experimental units, and one of which was fitted with amorphous silicon PV windows, and another was fitted with conventical window. According to the test results, it can be seen that, the PV film windows could save the 30% building load on typical sunny days, and provide additional 0.41 kWh/per day.
