When the operating temperature increases, the efficiency of the photovoltaic panel is reduced almost linearly. Figure 23. Variation of the efficiency of the PV panel with the operating temperature for G med = 520 W/m 2. Figure 24, Figure 25 and Figure 26 represent the coefficients of variation of PV panel parameters with temperature.
The operating temperature plays a key role in the photovoltaic conversion process. Both the electrical efficiency and the power output of a photovoltaic (PV) module depend linearly on the operating temperature.
This high temperature causes the cell surfaces to develop lower electrical efficiency and corrosion, resulting in the reduced service life of the PV panels. Empirical and theoretical studies have shown that high temperature is inversely linked to the PV module power out, and the PV panels performed better when a cooling process is applied.
It implies that the higher the temperature, the lower the voltage when other variables are kept constant and this causes power loss. Otherwise, the reverse happens, that is, power is gained; when the temperature decreases, the PV output rises in voltage concerning the original conditions.
