This study evaluates an air-based photovoltaic thermal (PV/T) double-pass system integrated with paraffin wax phase change material (PCM). Three PCM masses, namely 1000 g, 2000 g, and 3000 g, were tested and compared under equal solar irradiance so that the thermal response could be evaluated under comparable radiation conditions. The apparatus consists of a PV module, 6 mm glass cover, air duct, reflector/absorber plate, PCM containers, type-K thermocouples, DHT22 sensors, solar power meter, anemometer, Testo 405i probe, and data logger. The results show that the average air temperature difference was 6.74°C, 6.72°C, and 6.91°C for PCM 1000 g, 2000 g, and 3000 g, respectively. The average reflector temperature decreased from 44.97°C at PCM 1000 g to 43.45°C at PCM 3000 g, indicating better heat buffering with larger PCM mass levels.
