Solar panel efficiency drops by around 0.05 percent for every degree Celsius increase in temperature. On the other hand, efficiency increases by 0.05 percent for every degree Celsius decrease in temperature.
This phenomenon occurs due to the nature of the materials used in solar panels, such as silicon, which are sensitive to temperature changes. As the temperature increases, the efficiency of solar panels tends to decrease, impacting their energy output.
High temperatures cause the semiconductor materials in photovoltaic cells to become more conductive, reducing the voltage generated. Proper installation and airflow around solar panels can help dissipate heat and maintain efficiency. Selecting solar panels with a low-temperature coefficient can mitigate the impact of high temperatures.
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.
Another strategy for maximizing solar panel performance in high temperatures is to select panels with lower temperature coefficients. The temperature coefficient is a measure of how much the power output of a solar panel decreases with increasing temperature.
Temperature regulation is essential to maintain the efficiency of solar panels. Excessive heat can reduce the performance of solar cells, leading to a decrease in the amount of electricity generated. The decrease in efficiency is primarily attributed to the increased resistance of the materials used in solar panels as temperature rises.
