•Effect of mass flow rate and the shape of the absorber plate factor is studied.•Various temperatures, exergy, and energy efficiency studied in MATLAB.•Curved groove absorber plate gives better PVT performance. The efficiency of the photovoltaic thermal (PVT) system is affected by the meteorological and climatic conditions. Studies based on mathematical modeling has been applied to optimize the PVT system using absorber shape factor (Z) and mass flow rate (m). Mathematical modeling of heat transfer coefficients and their simulation in MATLAB is presented in the current study using the meteorological data of three major cities (Ahmedabad, Delhi, and Pilani) of India. The scope of the present work is not only limited to finding the effect of solar radiation intensity and ambient temperature but also to establish the optimized value for Z and the best suitable shape for the absorber plate. The detailed analysis of results obtained shows higher values of m gives better total efficiency. For m = 0.02 kg/s but it is observed Z = 1.3 gives maximum efficiency, 48% at noon, in comparison to Z = 2 which is 43% for m = 0.1 kg/s. Hence curved grooved absorber plate is predicted to give better performance for various geographical locations.
