Numerical and experimental investigation for analyzing the temperature influence on the performance of photovoltaic module

<abstract> <p>The effect of temperature is considered a significant factor in controlling the output voltage of the photovoltaic (PV) module. In this work, a numerical analysis with an experimental demonstration were investigated to analyze the temperature effect on the performance of PV module. In the numerical part, the current-voltage I-V and power-voltage P-V curves of the PV module were simulated under the influence of various module temperature ranged from 25 to 65 ℃ as well as various solar radiation from 200 to 1000 W/m². In addition, the variation of PV output electrical characteristics with a module temperature were performed to analyze the temperature coefficients of the PV module. Moreover, the experimental demonstration was performed to analyze performance of the PV module under the real weather conditions of Iraq. The numerical results conclude that the maximum power was recorded 165 W at 1000 W/m² solar irradiance and 25 ℃ PV module temperature. Furthermore, the temperature coefficient was recorded a maximum value with output power about (−0.26) %/℃. Besides, the experimental results show that the maximum power was recorded 131.2 W at solar irradiance about 920 W/m².</p> </abstract>
