Abstract: Semi-flexible crystalline silicon photovoltaic (SFPV) modules, leveraging ultra-thin silicon and special encapsulation materials, feature innovative flexibility, lighter weight, and improved stability, making them ideal for rooftops with a load-bearing capacity under 15 kg/m2. This study experimentally evaluated the photovoltaic and thermal performance of a ventilated building-integrated semi-flexible crystalline silicon photovoltaic (V-BI-SFPV) system under warm climates, addressing the research gap in its performance under specific climatic conditions. The results indicate that the ventilated design of the V-BI-SFPV system significantly enhanced the power generation performance of the SFPV module, increasing its daily average photovoltaic efficiency by 7.37 % under grid-connected test conditions. Furthermore, the average and maximum operating temperatures of the SFPV module were reduced by 5.09 °C and 4.21 °C, respectively. The ventilated structure also effectively lowered the base plate temperature under high daytime temperatures, thereby reducing heat transfer into the building and mitigating overheating issues for both the SFPV module and the indoor environment. The findings demonstrate that the V-BI-SFPV system, with its effective enhancement of power generation efficiency and thermal management, offers a viable solution for rooftop photovoltaic applications with low load-bearing capacity.
