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.
Understanding how temperature affects solar panel efficiency is crucial for maximizing your renewable energy investment. As we’ve explored, solar panels generally perform best between 59-95°F (15-35°C), with efficiency dropping as temperatures rise above this range.
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.
In photovoltaic systems, performance primarily depends on light, but temperature also plays a role. When solar cells heat up, their electrical behaviour changes: voltage decreases and conversion efficiency drops. This effect is factored into the panel’s design. The key lies in the balance between light capture and thermal management.
