摘要
提出了1种光伏组件相对温度系数测试解决方案(下文简称为“解决方案”),其采用集成了比例-积分-微分(PID)恒温控制系统的脉冲式太阳模拟器;然后选取TOPCon双面双玻、HJT双玻、背接触(BC)单玻光伏组件对该解决方案进行了测试验证。研究结果表明:1)该解决方案可以将温度偏差控制在±1℃、在5~10 min内快速完成光伏组件温度均匀性整定并进入精确测试过程;同时其采用已获得专利的高效I-V测试方案,有效减少了由电容效应引起的瞬态误差。各类光伏组件的测试结果表明,恒温5~10 min与恒温30 min的测试结果具有高度一致性,并表现出较高的稳定性和可重复性。该解决方案在温度控制、测试精度和测试效率方面均具有显著优势。2)在测试双面光伏组件单面工作时的相对温度系数时,创新性地避免了对双面光伏组件背面进行遮挡的测试需求,进一步提高了测试的便捷性和效率。研究结果为光伏组件的性能评估提供了更加高效和精准的测试方法,也为光伏测试设备的进一步发展和行业技术进步提供了新的视角和思路。
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.
