Abstract Scope |
Solar modules in field are subject to cyclic thermomechanical loading, emphasizing the need for proper module design to resist thermal expansion incompatibility. However, isolating the impact of confounding components on overall durability remains a challenging task. In this work, we collected bill-of-materials data and thermal cycling power loss from over 250 distinct module designs. We developed a machine learning model to correlate design factors with the degradation and applied Shapley additive explanation to interpret the impacts of design factors. Our analysis reveals that the type of silicon cells predominantly influences the degradation, and monocrystalline cells present better durability. This finding was further substantiated by statistical testing. We also demonstrate the thickness of the encapsulant remains another important factor, with thicker encapsulants correlated with reduced degradation. The study here provides a blueprint for utilizing explainable machine learning in intricate material system and can potentially steer future optimization of solar module design. |
