Abstract: Photovoltaic technology is one of the most ideal alternatives for the traditional power generation system. However, the traditional large-scale solar power generation system is not suitable for high-density cities such as Hong Kong. The building integrated photovoltaic system (BIPV) is a superior solution which will reduce land and space utilization. During the design and construction process of BIPV system, numerous additional problems could reduce the system performance due to the installation method or defect of design. The unique effect of local climate on the operation of photovoltaic power generation system must be taken into consideration. Since there are multiple factors which could affect the system efficiency, the weather condition in realistic situations is quite different from that of standard test conditions (STC). Thus, a prediction model is needed to make predictions of PV panel power generation property with limited climate data. However, the majority of the recent researches have only focused on influential factor. Others simply focused on the solar radiation forecast or system photovoltaic conversion efficiency of the PV module. In this study, a novel solar radiation conversion model was built initially, which generated accurate prediction result of real-time solar radiation on any tilt angle and orientations based on the hourly total and diffusion solar radiation intensity data. The suitability of this prediction model was proved by data measured from the experiment devices working under actual situation of Hong Kong. This prediction model will also help to save the cost of purchase. It will be a powerful tool to promote BIPV technology application and development in Hong Kong. In the end simulation results were demonstrated and analyzed. The prediction results, which generated by the power generation prediction model using the meteorological data from Kau Sai Chau Observatory, were in-depth analyzed. After review the analysis of the prediction results, conclusions of the entire research and suggestions for system design and operation were given.
