Abstract

Pavement Integrated Photovoltaic Thermal (PIPVT) systems represent a novel approach that utilizes existing infrastructure to harvest electrical and thermal energy simultaneously. While prior research has primarily relied on simplified numerical models or limited laboratory testing, this study conducts a full-scale experimental campaign to provide a crucial empirical analysis of a novel PIPVT system under outdoor conditions. The system integrates a serpentine pipe network within the pavement, serving a dual purpose: actively cooling the photovoltaic (PV) cells to enhance their electrical efficiency and harvesting thermal energy from the road surface. Furthermore, the transient dynamics of an integrated thermal storage unit were monitored and analyzed in this study. An experimental setup was fabricated and tested outdoors to analyze the system's performance at two water mass flow rates: 0.05 kg/s and 0.12 kg/s.
