Abstract

The research presents the daily and monthly global solar radiation on a horizontal surface in Iraq and applies it to the PVT water system. The research contributes in two ways: first, it models a novel copper pipe system that improves thermal efficiency in an actual environment, and second, it investigates the hourly and daily intensity of solar radiation in Iraq using collected irradiation at mass flow rates ranging from 0.01 to 0.02 kg per second, the surface temp of the PVT model was calculated. The surface temp was also computed using the experimental data in the PVT model. The findings were consistent with those of prior investigations. A PVT system with a constant input temp is employed to raise the surface temp throughout simulated testing with an optimal mass flow rate of 0.02 kg/s and a constant low input temp, the findings demonstrate the thermal efficiency of the PVT. February records the highest thermal efficiency and 12 pm records the highest radiation comparison with other selected months.
