How Temperature Affects Photovoltaic Solar Energy Conversion

Solar panels are designed to harness sunlight, but temperature plays a significant role in their efficiency. While many assume that hotter conditions lead to better energy production, the opposite is often true.

1. The Basics of Temperature Coefficient
   • Solar panels are most efficient at specific temperatures, typically around 25°C (77°F). When the panel’s surface temperature rises above this threshold, its efficiency decreases.
   • The rate of efficiency loss per degree Celsius is called the temperature coefficient, which is usually between -0.3% and -0.5% for most panels.
2. High Temperatures and Energy Output
   • In hot climates like the Algarve, solar panels can heat up to 60°C or more, leading to a reduction in
     photovoltaic Solar Energy Conversion efficiency by up to 20%.
   • This reduction occurs because high temperatures increase the internal resistance of photovoltaic cells, hindering the flow of electricity.
3. Cold Weather Benefits
   • On cooler, sunny days, panels operate more efficiently, producing more electricity for the same amount of sunlight.
   • This is why solar installations in the Algarve can still perform excellently during the mild winter months when many international homeowners return to their properties.
