Assessment of long term reliability of photovoltaic glassglass modules vs. glass-back sheet modules subjected to temperature cycles by FE-analysis
Investigation of thermo-mechanical reliability of photovoltaic modules by FEM. Comparison of two module types called glass back sheet and glassglass modules. No deflection of glassglass module owing to temperature changes due to symmetry. Higher solder creep in glassglass assembly after temperature cycles. Double plastic strain of copper ribbon in glassglass compared to glass back sheet.
