Quick Answer
The best mounting options for solar panels depend on the environment and system design, but common choices include fixed tilt systems, tracking systems, and racking systems that allow for adjustable angles and orientations.
Choosing a Mounting System
When selecting a mounting system for solar panels, consider the climate and local regulations. For off-grid systems, a fixed tilt mount can provide efficient energy production while minimizing costs. A fixed tilt mount typically ranges from 15° to 40°, with 22° being a common angle for optimal energy production in the US. Ensure the mounting system can handle wind loads and roof weight, especially for residential installations.
Tracking Mounts: An Alternative Option
Tracking mounts, also known as dual-axis mounts, can increase energy production by 30-50% compared to fixed tilt mounts. These systems adjust the angle of the solar panels to follow the sun’s movement throughout the day, optimizing energy production in high-sun-angle environments like deserts or coastal areas. Tracking mounts are a more expensive option but can be beneficial for large-scale commercial installations or those with high energy demands.
Racking System Considerations
Racking systems, also known as solar panel racks, allow for adjustable angles and orientations, making them versatile for various roof types and environments. Look for racking systems with adjustable legs, ensuring proper alignment and leveling. A sturdy racking system can support a wide range of panel sizes and weights, making it a suitable option for large-scale installations or those with varying panel sizes.
