摘　　要：太阳能光伏(PV)系统在我国的应用十分广泛,但还缺乏其在不同区域的资源利用潜力分析.建立了太阳能光伏发电潜力评估方法,通过搭建实验台研究3种常用太阳能光伏系统的转换效率和环境参数的关系,并拟合出光伏效率方程.借助地理信息系统(GIS)平台的空间分析功能研究我国各地太阳能辐射强度频数和发电潜力空间分布.通过分析发现单晶硅组件在我国西北和北方地区高达200kWh/(m2·a)以上,适宜发展PV系统,而西南地区仅约130kWh/(m2·a),可以为各地发展太阳能和制定能源发展规划提供参考.Solar photovoltaic(PV)systems are widely utilized in our country.However,the associated study about its resource potential analysis is still short of in variant districts.Based on the existed data about solar radiation and conversion efficiency,methods for photovoltaic potential assessment were established.An experiment platform for three common kinds of solar photovoltaic systems was developed for the purpose of analyzing the relationship between conversion efficiency and environmental parameters.A calculating formula for conversion efficiency and solar radiation intensity was fitted.With the help of the spatial analysis function of the geographic information system(GIS)platform,the frequency distribution of solar radiation intensity and the solar PV electricity potential in China were derived.T he analytical results show that m onocrystalline-silicon PV electricity in northw estern and northern areas have reached a level of m ore than 2 0 0 kW h/(m2·a),m aking those areas be suitable for the developm ent of PV system.H ow ever,the potential in southw est areas reaches a level of only 1 3 0 kW h/(m2·a).T his can provide a baselinereference for solar energy development planning.
