This article examines how the efficiency of a solar photovoltaic (PV) panel is affected by the ambient temperature. You’ll learn how to predict the power output of a PV panel at different temperatures and examine some real-world engineering applications used to control the temperature of PV panels.
The dependence of the series resistance for all photovoltaic cells on temperature at 1000 W/m 2 irradiance is presented in Figure 11(a). The series resistance decreases linearly with the increase in temperature. The series resistance is determined by the semiconductor resistivity and the resistance of the metal conductors.
With an increase of ambient temperature, the temperature rise of solar cells is reduced. The characteristics of panel temperature in realistic scenarios were analyzed. In steady weather conditions, the thermal response time of a solar cell with a Si thickness of 100–500 μm is around 50–250 s.
Temperature—Solar cells generally work best at low temperatures. Higher temperatures cause the semiconductor properties to shift, resulting in a slight increase in current, but a much larger decrease in voltage. Extreme increases in temperature can also damage the cell and other module materials, leading to shorter operating lifetimes.
