Investigation on Photovoltaic Application in Buildings in China

With the rapid development of photovoltaic (PV) industry and vigorous incentive policies in China, the domestic application of PV has had “explosive” growth in recent years. The application in buildings is also worth of attention to find the solution of PV application in buildings and solve the problems emerged today, that is the basis to promote the PV systemsas distributed energy. In this paper, the status of PV application in buildings in China is selectively analyzed, based on the relative information of domestic PV projects. Samples of statistical analysis are 1504 PV projects from part of the domestic ones built up during 2009 to the end of 2012, mainly come from “Golden-sun Demonstration Project” and “Photovoltaic Roof Demonstration Project”. And the capacity of samplesis 6983MW which takes up 87.1% of the nationwide accumulative installed capacity by the end of 2012. The distribution status, installation form with buildings and system performance are statistically analyzed. Meanwhile some problems and suggestions such as the rationality of regional distribution, the building integration forms are discussed and the system performance improvement method are proposed. It is expected to make some contribution to the application of PV in buildings in the future in China.
