 Thermal characterization of a photovoltaic panel under controlled conditionsThomas Villemin, Rémy Claverie, Jean-Paul Sawicki and Gilles Parent Renewable Energy, 2022, vol. 198, issue C, 28-40 Abstract: To avoid large variability in environmental factors, the thermal and electrical behavior of a 310 W PV panel exposed to a 6 kW halogen light source was studied in a 48 m3 climatic room. The physical quantities measured were panel temperature (front and back), radiation illuminating the panel, ambient temperature, air speed, panel current and panel voltage. Under these conditions, it was possible to estimate the thermal constant of the panel at 9 minutes. The effect of forced convection on the panel temperature was quantified using a fan. The results obtained confirm that the panel temperature decreases exponentially with air speed. The part of the incident radiation that is converted into electricity and therefore does not contribute to the heating of the panel was quantified. The results show that the front panel temperature decreases by about 3°C and the rear panel temperature by about 3.7°C when the system produces electricity. The Maximum Power Point from I–V and P–V characteristics was studied for different PV temperatures to confirm the linear decay of the electrical efficiency with increasing cell temperature.
