Özet
The operating temperature is the most important factor impacting PV module performance.
When it exceeds 25 °C, the electrical power and efficiency decrease. The purpose of this
research is to improve thermal performance and compare the performance of two common
crystalline PV panel types (Mono and poly). Modules with a back-cooling system were
designed and numerically analyzed with SolidWorks and ANSYS Fluent 2021 R2 for the
simulation under Baghdad weather at noon. The cooling system used consists of a phasechange material, paraffin wax (RT55), with a thickness of 5 cm and a heatsink with 33 fins
with heights of 10, 20, and 30 mm and thicknesses of 2, 4, and 6 mm. to select the best
height of the wax 1-3-5-10-20 cm examined. The result showed for polycrystalline panel
temperature reduced by 8.4 °C using PCM and by 11.9°C using PCM- fins. Also output
power enhanced to 200.6 W by 10.2 W, and its efficiency improved by 5%. Similarly, the
use of PCM and PCM-fins lowered the temperature of the monocrystalline by 8.3 and 12.5
°C, respectively. Therefore, raising the output power to 202.4 W by 10.7 W and improving
the electrical efficiency by 5.2%. The results of the study showed that mono had better
performance than poly. This result is acceptable and is in good agreement with previous studies. The proposed cooling system also had an effective role in reducing the temperature
and improving performance.
