The innovative mounting solution (Coolback® system) is a combined mounting and passive cooling structure which replaces the backsheet and the frame. We simulate the mechanical load test comparing a conventionally framed module to one using the Coolback® system. Both laminates are identical and consist of a 60-cell and a 144-half-cell/72-cell configuration. The finite element method simulations show that the cooling fins reduce the deflection of the module significantly, resulting in negligible solar cell fracture probabilities for all loads. Especially at high loads, where the framed module has a high solar cell fracture probability, the increased mechanical stability caused by the cooling fins helps to reduce cell fracturing.enPhotovoltaikPhotovoltaische Module und KraftwerkeModultechnologieGebrauchsdauer- und Schadensanalysesimulationelement methodeloadmountingframe621697conference paper
