According to the manufacture standards, 25 °C or 77 °F temperature indicates the peak of the optimum temperature range of photovoltaic solar panels.
Solar panels perform optimally in moderate temperatures up to 77°F. Generally, a panel’s efficiency degrades as temperature increases over 77°F.
To put a single number on it, however, it is generally believed that the ideal operating temperature for an average solar panel is around 77 degrees Fahrenheit or 25 degrees Celsius.
The predicted panel temperature is as high as 60 °C under a solar irradiance of 1000 W/m 2 in no-wind weather. In realistic scenarios, the thermal response normally takes 50–250 s.

6 FAQs about [Working ambient temperature of photovoltaic panels]
Does heating affect photovoltaic panel temperature?
The actual heating effect may cause a photoelectric efficiency drop of 2.9–9.0%. Photovoltaic (PV) panel temperature was evaluated by developing theoretical models that are feasible to be used in realistic scenarios. Effects of solar irradiance, wind speed and ambient temperature on the PV panel temperature were studied.
What temperature should a solar panel be at?
According to the manufacture 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. The solar panel output fluctuates in real life conditions.
Does ambient temperature affect solar panel temperature?
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.
What temperature should solar panels be in a heat wave?
The optimal temperature for solar panels is around 25°C (77°F). Solar panels perform best under moderate temperatures, as higher or lower temperatures can reduce efficiency. For every degree above 25°C, a solar panel’s output can decrease by around 0.3% to 0.5%, affecting overall energy production. Why Don’t Solar Panels Work as Well in Heat Waves?
How does temperature affect the efficiency of a PV panel?
As the temperature of a PV panel increases above 25°C (77°F), its efficiency tends to decrease due to the temperature coefficient. The coefficient measures how much the output power decreases for every degree Celsius above a reference temperature (usually 25°C).
How long does a photovoltaic panel take to heat up?
In realistic scenarios, the thermal response normally takes 50–250 s. The actual heating effect may cause a photoelectric efficiency drop of 2.9–9.0%. Photovoltaic (PV) panel temperature was evaluated by developing theoretical models that are feasible to be used in realistic scenarios.
