The temperature of solar photovoltaic (PV) panels increases due to solar irradiation, which leads to decreased power generation. To decrease the temperature, an improvement in convective cooling is needed. It can be achieved by airflow modification using a vortex generator (VG). This study investigated the effect of a rectangular-shaped winglet vortex generator (RWVG) on the performance of a solar PV model. The RWVG was designed with four different attack angles, configured in a common flow-up orientation. The attack angles (β) were adjusted from 30º, 50º, 60º, and 70º. Additionally, the Reynolds numbers (𝑅𝑒) were varied under 724, 1086, 1448, and 1810. The experimental setup was equipped with a thermal camera to capture the temperature distribution on the solar PV model surface. Results indicated that the solar PV equipped with the RWVG at an attack angle of β = 50° exhibited the highest performance, showing a 30.85% improvement in the convection heat transfer coefficient and a thermal performance enhancement of 1.36 times. As the Reynolds number increased, performance tended to improve within the variations studied. Visual observations confirmed that the RWVG at β = 50° achieved the greatest temperature reduction, approximately 21.1%.
