Fraunhofer ISE has developed a lightweight PV module concept using glass fiber-reinforced polymers (GFRP) based on epoxy composites. According to the study, this design reduces weight by 44-74% compared to conventional glass-back sheet modules. The GFRP front material enables hail impact resistant modules, both small and large, without cell cracks after impact. Additionally, modules with GFRP front layers withstand thermal cycling tests with low power losses of -0.9% to -1.1% at Pmpp. The tests also show increased performance in cut susceptibility tests compared to polymeric front layers. Fraunhofer ISE’s vacuum-infiltrated GFRP modules meet IEC 61215 standards for hail resistance, with average hail-induced power changes of -1.2%. Furthermore, 3D X-ray microscopy detected no impact-induced damages in the GFRP front-sheet.
