Abstract: The energetic, exergetic, electricity, and environmental analyses of a photovoltaic-thermal (PV-T) panel combined with a parabolic trough solar collector (PTSC) are numerically for four selected sunny days in January, April, July, and October. The system essentially generates electricity and thermal energy. Thermal energy is produced by increasing the cooling water temperature used for the PV-T with the help of the PTSC. The system's maximum energy and exergy efficiency was obtained at 57.42% and 14.80% in July and January. Also, total carbon savings and electricity generation were found as 6.4881 kg, 12.0555 kg, 15.9464 kg, and 11.2239 kg and 18.3077 MJ, 26.72 MJ, 31.906 MJ, and 25.637 MJ a day in January, April, July, and October, respectively. The average temperature of the water was increased from 31.76°C to 85.20°C from winter to summer.

Keywords: thermal energy storage; parabolic trough solar collectors; photovoltaic thermal collector; energy and exergy efficiency; carbon saving.
