Abstract
A new model has been developed in this paper to evaluate the impact of different photovoltaic modules on room, floor, and solar cell temperature, along with daylight savings and solar cell electrical efficiency. Computations have been carried out on a building-integrated semitransparent photovoltaic thermal system integrated with the roof of a room for Varanasi climatic conditions in winter months. The electrical efficiency of the module and temperature coefficient impact the system's performance significantly. Mono-Si, poly-Si, amorphous Si, and Photovoltaic Thermal (PVT) systems are discussed. Compared with the previous model, the results of the study indicate that there is a 4.39% decrease in the overall exergy efficiency; hence, the PVT system is recommended for energy efficiency, and m-Si is suitable for electrical exergy.
