Abstract
This paper proposes a solution for the relative temperature coefficient test of PV modules(hereinafter referred to as the"solution"),which uses a pulse type solar simulator integrated with PID constant temperature control system.Then,TOPCon bifacial glass bifacial PV modules,HJT bifacial glass PV modules,and BC single-glass PV modules are selected to test and verify the solution.The research results show that:1)This solution can control the temperature deviation within±1℃,quickly complete the temperature uniformity tuning of PV modules within 5～10 min,and enter the precise testing process.At the same time,it adopts an efficient I-V testing scheme that has been patented,effectively reduces transient errors caused by capacitance effects.The test results of various PV modules show a high degree of consistency between the 5～10 min constant temperature test and the 30 min constant temperature test,and demonstrate high stability and repeatability.This solution has significant advantages in temperature control,testing accuracy,and testing efficiency.2)When testing the relative temperature coefficient of bifacial PV modules during single-sided operation,the innovative approach avoids the testing need for covering the back of the bifacial PV modules,further improving the convenience and efficiency of testing.The research results provide a more efficient and accurate testing method for the performance evaluation of PV modules,as well as new perspectives and ideas for the further development of PV testing equipment and industry technological progress.关键词
