为研究单轴跟踪支架檩条尺寸对光伏组件玻璃受力特性的影响,本文开展了机载试验,采用3种不同规格的檩条进行对比分析。通过对光伏组件玻璃表面应变数据的采集,分析不同檩条尺寸对光伏组件玻璃在受力过程中的影响规律。实验结果表明:光伏组件玻璃的应力在组件中心最大,且随着檩条截面高度的增加,组件玻璃的应力有所降低;进一步增加檩条长度后,整体受力明显减小。研究结果为光伏组件的设计与优化提供了理论依据,表明适当的支架尺寸选择可有效减小光伏组件玻璃的受力,提高其稳定性与可靠性。
Abstract:This study examines the influence of purlin dimensions on stress characteristics of photovoltaic(PV) module glass in single-axis tracking systems through mechanical tests comparing three purlin specifications. By collecting strain data on the surface of the PV module glass, the influence of various purlin sizes on the stress distribution of the glass during loading was analyzed. The experimental results indicate that the stress on the PV module glass is highest at the center of the module and decreases with an increase in the cross-sectional height of the purlin. Furthermore, extending the length of the purlin significantly reduces the overall stress. The findings provide a theoretical basis for the design and optimization of PV modules, demonstrating that appropriate selection of support dimensions can effectively reduce the stress on the PV module glass, thereby enhancing its stability and reliability.
