Several tests were conducted to ratify the reliability and durability of the solar photovoltaic (PV) devices before deployment in the real field (non-ideal conditions). In the real field, the temperature of the PV modules was varied during the day and night. Nowadays, people have been bearing in mind the deployment of PV modules on concrete roads to make use of the space accessible on roads. In this regard, a comparative study on the failure and degradation behaviors of crystalline Si PV modules with and without a concrete slab was executed via a thermal cycling stress test. The impact of the concrete slab on the performance degradation of PV modules was evaluated. Electroluminescence (EL) results showed that the defect due to thermal cycling (TC) stress was reduced in the PV module with a concrete slab. The power loss due to the thermal cycling was reduced by approximately 1% using a concrete slab for 200 cycles. The value was reduced to approximately 91% and 71% after thermal cycling of 200 cycles for reference PV modules, respectively. The value of was increased to approximately 3.1 and 2.9 times the initial value for the PV modules without and with concrete, respectively.
在将太阳能光伏（PV）设备部署到实际现场（非理想条件）之前，进行了多项测试以验证其可靠性和耐用性。在实际现场，光伏组件的温度在白天和夜晚会发生变化。如今，人们一直考虑在混凝土道路上部署光伏组件，以利用道路上可利用的空间。在这方面，通过热循环应力测试对有无混凝土板的晶体硅光伏组件的失效和退化行为进行了对比研究。评估了混凝土板对光伏组件性能退化的影响。电致发光（EL）结果表明，带有混凝土板的光伏组件中因热循环（TC）应力产生的缺陷减少。使用混凝土板进行200次循环后，热循环导致的功率损失降低了约1%。对于参考光伏组件，在进行200次热循环后，该值分别降至约91%和71%。对于无混凝土和有混凝土的光伏组件，该值分别增加到初始值的约3.1倍和2.9倍。
