摘　　要：介绍了一种将光伏发电与储热水箱相结合的热水系统,并对该系统在3种不同环境温度工况下的系统热性能进行了测试。结果表明,当光伏组串表面接收的太阳辐照量最大时,该系统的转换效率未必最高;同时,环境温度会对系统的转换效率产生影响,但环境温度并不是唯一的影响因素。An experimental platform is designed in this paper to simulate the practical application of PV power system combined with solar water heating system(PV hot water system)under three different temperatures.The results show that as the solar radiation which PV strings received from increases,the conversion efficiency may not increase.While,ambient temperature affects system conversion efficiency,respectively.But ambient temperature is not the only factor.
