1. Introduction The important role of the operating temperature in relation to the electrical efficiency of a photovoltaic (PV) device, be it a simple module, a PV/thermal collector or a building-integrated photovoltaic (BIPV) array, is well established, as can be seen from the attention it has received by the scientific community.
According to the manufacturing standards, 25 °C or 77 °F temperature indicates the peak of the optimum temperature range of photovoltaic solar panels. It is when solar photovoltaic cells are able to absorb sunlight with maximum efficiency and when we can expect them to perform the best.
In a solar cell, the parameter most affected by an increase in temperature is the open-circuit voltage. The impact of increasing temperature is shown in the figure below. The effect of temperature on the IV characteristics of a solar cell. The open-circuit voltage decreases with temperature because of the temperature dependence of I 0.

One of the empirical formulas to estimate PV cell temperature (TcellT_ {cell}Tcell) is based on the NOCT and actual operating conditions: Tcell=Tambient+ (NOCT−20800)×GactualT_ {cell} = T_ {ambient} + \left (\frac {NOCT – 20} {800}\right) \times G_ {actual}Tcell=Tambient+(800NOCT−20)×Gactual Where:
With regard to the relevant weather variables, and qualitatively speaking, it was found that the PV cell temperature rise over the ambient one is extremely sensitive to wind speed, less so to wind direction, and practically insensitive to the atmospheric temperature .
