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.
The chart’s downward slope indicates how solar panel power output decreases as temperature rises. Most charts show a baseline temperature of 25°C (77°F), which represents standard test conditions. For every degree above this baseline, efficiency typically drops by 0.3% to 0.5%, depending on the panel type.
According to UNEF, the optimal operating temperature for a solar panel is below 25°C. Higher temperatures can negatively impact efficiency. This thermal response doesn’t prevent daily production from being high in summer. Despite the heat, there are more hours of solar radiation, with little cloud interference.
Photovoltaic solar systems convert direct sunlight into electricity. Therefore, these panels don’t need heat; they need photons (light particles). ‘The optimal operating temperature for a solar panel is below 25 °C.’ When temperatures rise, so does the temperature of the cells, which can reduce their electrical output.
