英文摘要： Grid-connected Photovoltaic (PV) for urban building application is an important part of the civil economic- social sustainable development and environmental protection under urbanization. The research on key problems of building grid-connected PV, to reduce the negative impact of the uncertainty on the grid and backup capacity, will provide important theoretical basis for high efficiency and more economic building PV utilization, and have important practical significance for promoting the large-scale process by the national level and market. The project selects Wuhan, Shanghai and Beijing as the representative for central, eastern and North China with abundant solar resources and more developed economics, respectively. The project focuses on the accurate model of the total radiation on inclined surfaces and optimum tilt angle with distribution for building PV system, the influence principle analysis of critical meteorological-environmental factors on building PV efficiency and the coupling relationship between multiple variables to obtain the quantitative description of the mathematical model, the establishment of comprehensive performance evaluation system and the standard indicting regional differences based on the solar sources inherent characteristic and the process of meteorological power generation , and t
