Yes, certain brands and types of solar panels are preferred for their performance in extreme heat. Here are some key considerations and recommended brands:
Key Considerations for Solar Panels in Extreme Heat
- Monocrystalline vs. Polycrystalline: Monocrystalline panels generally outperform polycrystalline ones in high temperatures due to a better temperature coefficient. Monocrystalline panels experience an efficiency drop of about 5.25% at 40°C, compared to 6% for polycrystalline panels.
- Temperature Coefficient: A lower temperature coefficient (measured as %/°C) indicates better performance in heat. Panels with lower coefficients lose less efficiency per degree of temperature rise.
- Color and Design: Black panels can absorb more heat than those with lighter-colored or reflective surfaces, but the impact can be managed through proper installation and cooling techniques.
Recommended Brands for Extreme Heat
- Monocrystalline Brands:
- REC: Offers high-performance monocrystalline panels suitable for hot climates. The REC Alpha Pure series is particularly noted for its performance.
- LG NeON R: Known for its silver stripes, which can help in heat management by reflecting sunlight and reducing temperature.
- Panasonic: Known for producing reliable and efficient solar panels that perform well in high temperatures.
- Maxeon (formerly SunPower): Offers high-efficiency panels that are robust in hot conditions, though they come at a higher cost.
Additional Tips for Enhancing Performance in Extreme Heat
- Proper Installation: Ensure adequate airflow around the panels by mounting them several inches above the roof surface.
- NMOT (Nominal Module Operating Temperature): While useful for understanding operational conditions, it might not fully capture the impact of panel color on heat absorption.
- Thin-Film Panels: These typically have a low temperature coefficient, making them suitable for high temperatures, though their overall efficiency may be lower.
