The temperature coefficient of solar panels, which represents how much a panel’s power output decreases with each degree Celsius rise in temperature above 25°C, varies among different types of panels. Here’s a comparison:
- Monocrystalline and Polycrystalline Silicon Panels: These traditional panels typically have a temperature coefficient ranging from -0.3% to -0.5% per degree Celsius. Some brands, such as SunPower, have coefficients around -0.37% to -0.29%.
- Thin Film Solar Panels: These panels generally have a lower temperature coefficient, often closer to -0.2% per degree Celsius. This means they are less affected by temperature changes compared to monocrystalline or polycrystalline panels.
- Maxeon Monocrystalline Panels: These panels, known for their high efficiency, have a temperature coefficient of about -0.38%, which is slightly better than the average for monocrystalline panels.
In summary, while most traditional silicon-based panels have a similar temperature coefficient range, thin-film panels exhibit a lower sensitivity to temperature changes, offering advantages in hot environments.
