This paper analyses various factors on the optimum load matching in photovoltaic water pumping system (PVWPS). The PVWPS is simulated carefully under different static heads in load matching, the optimum results are obtained when the maximum of hydraulic work per peak watt capacity of solar cells is considered as the design target. The conclusions are quite helpful to the PVWPS design.

n this paper. the cond ition for the maximum daily efficiency of a photovoltaic application system is discussed. based on theoretical and experimental study of a 5kW photovoltaic pumping system. The simple criterion is ηd max = η(T/2).

以5kW太阳能光伏水泵系统为基础,探讨了光伏应用系统获得最大全日效率的条件。重点讨论了太阳能光伏阵列与应用系统功率匹配的关系,导出光伏应用系统全日效率最大的判定式并简化为η全max=η(T/2),即当全日效率η全正好等于最强日照条件下的瞬时效率η(T/2)时,全日效率将为最大值η全max。
