摘　　要：光伏并网发电是光伏应用的主流。一方面,光伏并网发电不需要蓄电池,成本相对较低;另一方面,太阳能发电可以在白天用电高峰时给电网提供电能,缓解电力紧张。对单晶硅、多晶硅、CIGS三种类型小型光伏并网电站的年发电量,月发电量,天发电量,时段发电量和逆变器的情况进行了分析。单晶硅光伏电站每千瓦的年发电量最多,CIGS电站次之,多晶硅电站最少。在一年中的7至11月份,各类电站发电量与其它月份相比较多。9至11月份,CIGS电站发电量最多,一年的其它时间单晶硅光伏电站发电量最高。逆变器的行为符合供应商的效率说明。Grid-connected power generation is the main application of photovoltaic system.On the one hand,it can generate low cost power without battery,and on the other hand,it can relax the tightness of daytime power demand.The annual,month,daily and period output of three grid-connected systems made of mono-crystalline solar cell,poly-crystalline solar cell,CIGS solar cell were analyzed in the paper.The results show that mono-crystalline grid-connected system produces the most electricity than the other two systems.About month output,all these three systems produce the relative more electricity during 7-11 months.The efficiency of mono-crystalline grid-connected system is the highest and the CIGS ranks the second.The performance of inverter accords with the efficiency instruction of supplier.
