The photocurrent at any specific module temperature and actual irradiance reaching the solar cell can be estimated as , , : (16) where, is the percentage change in current per unit rise in module temperature (%A/˚C), also known as temperature coefficient of I sc; = 1000 W/m 2; T STC = 25˚C and is the measured module temperature.
Hence, solar panels are more likely to be efficient at high altitudes because solar radiation increases with altitude in the atmosphere (about 8 – 12%/304.8 m) and atmospheric temperature is low with increasing wind speed to induce fast cooling of the solar panels due to decrease in air molecules, emissions and air temperature.

Yes, solar panels are temperature sensitive. Higher temperatures can negatively impact their performance and reduce their efficiency. As the temperature rises, the output voltage of solar panels decreases, leading to a decrease in power generation. What is the effect of temperature on electrical parameters of solar cells?
High temperatures can cause a decrease in panel efficiency due to the temperature coefficient. However, it's worth noting that solar panels still produce electricity even on hot days. They are designed to dissipate excess heat to maintain optimal operating temperatures.
Solar panels can reach temperatures around 66°C (150°F) or even higher under direct sunlight. The temperature increase is due to the conversion of absorbed sunlight into heat. Elevated temperatures can negatively impact solar panel efficiency, reducing energy production. Proper installation and ventilation can help mitigate this issue.
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?
The efficiency of solar PV is determined by three primary parameters: VOC, i.e. open circuit voltage; ISC, i.e. short circuit current; and Pom, i.e. maximum power output. Each of these parameters is affected by temperature.
