The maximum temperature solar panels can reach depends on a combination of factors such as solar irradiance, outside air temperature, position of panels and the type of installation, so it is difficult to say the exact number.
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.
The temperature coefficient of a solar cell is the amount by which its output voltage, current, or power changes due to a physical change in the ambient temperature conditions surrounding it, and before the array has begun to warm up.
At 25°C, solar photovoltaic cells can absorb sunlight efficiently and achieve their peak rated output. However, real-life conditions are far more dynamic anyway. The solar panel output fluctuates in real life conditions. It is because the intensity of sunlight and temperature of solar panels changes throughout the day.
It usually ranges from -0.2%/°C to -0.5%/°C. Therefore, it can be concluded that for every one degree Celsius rise and increase in the temperature, the solar system efficiency reduces between 0.2% to 0.5% as well. Several things can be done to mitigate the effects of temperature on solar panel efficiency, including:
As the temperature increases, the electrons in the solar cell become more energetic, reducing the bandgap of the semiconductor material. This leads to several effects: Decreased Open-Circuit Voltage: The most significant effect is a reduction in the cell’s open-circuit voltage. This decrease is typically around 2.2 mV per °C for silicon cells.
