为了实现太阳能光伏发电系统中用于冷却太阳能电池的低品位热能利用,本文提出了太阳能光伏热水系统。通过对单体光伏光热系统（PV/T）的实验研究表明,在单体PV/T放置角度为30°,流量为200 L/h时,集热效率可达到最大值65.6%,系统的平均发电效率为14.3%,瞬时综合效率最大为83%,达到了能量的梯级利用。
To realize the use of low-grade thermal energy after cooling solar cells in solar photovoltaic systems,this paper puts forward a solar photovoltaic hot water system（PV/T）.The experiment of the PV/T system shows,at the condition that inclination is 30°,and flow rate is 200 L/h,the maximum heat-collecting efficiency can be achieved at 65.6%and the average power generation efficiency is 14.3%, the maximum instantaneous overall efficiency is 83%,which realize the cascade utilization of energy.
