摘要
采用便携式I-V测试仪在户外进行光伏组件最大功率测试时,测试结果会不同程度地受到外界因素的影响,从而使得到的光伏组件最大功率测试结果出现偏差。本文通过对比不同外界因素(比如:太阳辐照度、辐照计摆放位置、光伏组件工作温度及风速等)下测试得到的光伏组件最大输出功率值,分析不同外界因素对户外采用便携式I-V测试仪进行光伏组件最大功率测试结果的影响,以期为户外光伏组件最大功率测试提供一种最优的测试方案。
When using a portable I-V tester to test the maximum power of PV modules outdoors,test results will be affected to varying degrees by external factors,resulting in deviations in the test results of the maximum power of PV modules.In this paper,by comparing the maximum output power values of PV modules obtained under different external factors(For example:solar irradiance,radiometer placement position,working temperature of PV module and wind speed,etc.),the influence of external factors on the maximum power test results of PV modules using a portable I-V tester is analyzed.This paper hopes to provide an optimal test solution for the maximum power test of outdoor PV modules.
