The present paper illustrates an experimental and comparative thermal analysis of reflective (white) and non-reflective (black) roofing membranes paired with thin-film solar photovoltaic (PV) panels. Tests were carried out on two different membranes, thermoplastic olefin (TPO), and ethylene propylene diene monomer (EPDM). Solar irradiance along with temperature readings on the surface, between the panel and membrane, and below the membrane were recorded for 30 months at 15 minute intervals. The data was processed and the temperature effect was observed. Theoretical analysis was performed and results were compared to the experimental readings for verification. In the heat transfer analysis, radiation and convection to/from the assemblies were considered along with conduction through the PV and the roofing membranes. The interface temperatures for TPO/PV and EPDM/PV assemblieswere found to be different, which could affect roofing material degradation as well as solar panel performance depending on the material type used in fabricating the photovoltaic panels.
