摘　　要：光伏组件的安装倾角直接影响其输出特性,对光伏组件安装倾角的研究有利于光伏阵列的安装和调试。本文使用太阳能模块分析仪(PROVA),在户外实地测试了多晶硅光伏组件的电学参数(V、I、P),分析了光伏组件在不同时间段的输出特性,并对跟踪与非跟踪两种条件下的光伏组件输出功率做了对比。结果表明:当光伏组件正南方向安装,倾角为18°时,相对于其他角度,光伏组件输出特性都表现出较好的值;跟踪与非跟踪两种情况的对比表明,相同辐照条件下,对同一个光伏组件,跟踪条件下,光伏组件的输出明显较好,并且最佳倾角的变化受太阳运动规律的影响,呈现一个从大到小再到大的一个过程,而且这一结论与理论推导相吻合。The installation tilt angles directly affects the output characteristics of PV modules,and the research of the installation angles can be integrated to evaluate the working state of PV modules. In this paper,through the test of electrical parameters of polycrystalline silicon PV modules（ V,I,P） analysis of the output characteristics of PV modules in different time with PROVA devices. The power and efficiency output had been compared under the condition tracking and fixed setting. Results indicate that when the PV modules had been installed south direction,the tilt angle is 18 degrees,the output characteristics of PV modules exhibited good value. When PV modules is tracking solar energy,under the same irradiation condition for the same PV modules,the output of PV module was better,and the optimal tilt angle had been affected by the apparent motion of the sun,and Theoretical deduction and practical testing are the same.
