In this paper, we conducted a theoretical study using the TRNSYS program to simulate and analyze the impact of various parameters on the thermal performance of a hybrid photovoltaic/thermal solar collector in Mosul, Iraq, during November. A complete theoretical model of the hybrid photovoltaic/thermal solar collector was developed, including all components, setting all constants, and performing all necessary simulations to obtain the results. The results of the study indicate that a 2 m2-8 m2 increase in surface area resulted in a 16 percent increase in thermal efficiency and an 18 percent increase in solar fraction. In addition to these two results, the increase also yielded a 6 percent increase in the efficiency of the solar panels. When the packing factor ratio increased from 0 percent to 100 percent, thermal efficiency decreased by 24 percent and solar fraction by 16 percent. The increase in solar panel efficiency resulted from variations in slope angles. The slope angle of solar panels increased from 0 to 90 degrees, resulting in a variable influence on thermal performance, with a maximum value of 50 degrees at 52 degrees. The maximum solar energy produced by solar panels was achieved at slope angles of 29 degrees and 27 degrees, respectively.
