Effect of High Temperature on the Performance of Crystalline Silicon Photovoltaic Modules under Al-Kut Climatic Conditions, Iraq

The electrical performance of photovoltaic systems is very sensitive to operating temperature, making thermal effects an important factor when evaluating energy yield in hot climates. This study investigates the effect of elevated temperature on the performance of a crystalline silicon photovoltaic module (Canadian Solar CS6.2-66TB-615) under real weather conditions in Al-Kut/Iraq during the month of April. Temperature correction models have been used to evaluate versions in open circuit voltage, maximum power voltage, short circuit current, output energy and conversion efficiency relative to conventional check conditions. The consequences display that increasing mobile temperature results in a significant decrease in voltage-dependent parameters because of their bad temperature coefficient, whilst the modest boom in current is inadequate to make amends for the voltage losses. As a result, maximum power and efficiency lower as temperature will increase, with the maximum suggested performance degradation going on throughout the afternoon thermal top. These findings confirm that high temperature represents a significant performance limiting factor for crystalline silicon solar cells in hot environments and emphasize the need for thermally optimized system design, accurate performance modeling and mitigation strategies to maintain energy yield in regions of intense solar radiation and high ambient temperatures.
