As the temperature rises, the output voltage of a solar panel decreases, leading to reduced power generation. For every degree Celsius above 25°C (77°F), a solar panel’s efficiency typically declines by 0.3% to 0.5%.
The objective of this research is to identify the temperature effect on the solar photovoltaic (PV) power generation and explore the ways to minimize the temperature effect. The photovoltaic (PV) cells suffer efficiency drop as their operating temperature increases especially under high insolation levels and cooling is beneficial.
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:
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.
Several factors contribute to the operating temperature of a solar panel: Ambient Air Temperature: The surrounding air temperature is a primary factor. 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.
On the other hand, cold temperatures can initially boost the conductivity and voltage output of solar panels, but prolonged exposure to extreme cold can result in decreased sunlight availability, increased resistive losses, and reduced panel efficiency. To mitigate the effects of temperature on solar panel efficiency, certain measures can be taken.
How Does Temperature Affect Solar Panel Energy Production?
