Analysis of the impact of roof construction design on the thermal exchange and electrical performance of monofacial photovoltaic modules

This paper investigates the impact of roof construction features on thermal exchange in the electrical properties of monofacial photovoltaic modules, with special attention to Tedlar temperature. Simulations were performed in EnergyPlus to model different scenarios combining thermal properties of materials and the use of insulators, considering their ability to limit heat flow from the roof to the module. The analysis also includes variations in the most common surface tones (white, red and others) and in the structural geometries of the roof, evaluating their influence on the thermal properties of the module. Results may show that the use of thermal insulators can reduce the heat transferred from the roof to the module, but could also cause heat accumulation in the tedlar, which would affect its thermal performance. This study aims to optimize the thermal conditions of photovoltaic modules on urban roofs, proposing construction design strategies to maximize their energy efficiency in hot climates.
