When considering solar panels for hot climates, pay attention to the temperature coefficient. This tells you how much efficiency the panel loses for every degree above the standard test temperature of 25°C (77°F). Panels with a lower temperature coefficient, closer to zero, perform better in high temperatures.
Panels will typically operate at 20°C to 40°C above the surrounding air temperature. Solar Irradiance: More intense sunlight leads to higher panel temperatures. Under full sun conditions, panel temperatures can easily reach 50-65°C. Wind Speed: Wind can help cool panels, potentially improving efficiency.
When discussing solar panel efficiency and temperature, one crucial term to understand is the “temperature coefficient.” This metric quantifies how much a panel’s power output changes for each degree Celsius change in temperature above or below 25°C. The temperature coefficient is expressed as a percentage per degree Celsius.
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:
Although extreme conditions will affect solar panel performance efficiency, solar panels are rated to operate in a very wide temperature range. Designed to reflect real-world conditions, most solar panels have an operating temperature range wide enough to cover every single day of your system’s multi-decade lifetime.
As such, the manufacturer’s performance ratings of solar panels are usually tested at 77°F (25°C) or what’s called “standard test conditions.” To get a bit technical, solar panels are rated with specific high and low “temperature coefficients” that represent efficiency losses related to temperature changes above or below 77°F.
