Quick Answer
Adjustable mounts are better suited for hot environments as they allow for optimal tilt and azimuth adjustments to reduce thermal losses and maintain efficient energy production.
Choosing the Right Mount for Hot Climates
When selecting a solar mount for hot environments, it’s essential to consider the thermal impact on the system’s performance. Adjustable mounts offer greater flexibility, enabling you to adjust the tilt and azimuth of the panels based on the time of day and season. This adjustment allows you to optimize energy production while minimizing thermal losses.
Adjustable Mount Features for Hot Climates
In hot environments, it’s crucial to choose a mount with the following features: a wide range of tilt (0° to 90°) and azimuth (-45° to 45°) adjustments, precision mechanical components, and a durable, weather-resistant design. A good starting point for tilt adjustment is to set the panels at an angle slightly higher than the latitude of your location. For instance, if you’re at 35° latitude, set the panels at around 40° to 45° tilt.
Thermal Considerations and Performance
When it comes to hot environments, thermal derating is a significant concern. To mitigate this, consider using a mount with integrated shading devices, such as a canopy or louvers, to block direct sunlight during peak hours. Additionally, look for mounts with a high-quality coating or film that helps to reduce thermal losses. Some studies suggest that even a 1° change in panel tilt can result in up to 5% improvement in energy production in hot climates.
