Quick Answer
The best racking systems for ground-mounted solar arrays are typically those that offer high strength-to-weight ratios, ease of installation, and compatibility with a wide range of panel sizes. Top brands include IronRidge, Unirac, and Schletter. These systems often feature adjustable tilt and azimuth capabilities.
Key Considerations for Ground-Mounted Racking Systems
When selecting a racking system for a ground-mounted solar array, consider the site’s terrain, the type and size of panels to be used, and local building codes. Ensure the chosen racking system is designed to withstand local wind and snow loads, and is compatible with the specific panel model and frame configuration.
Adjustable Tilt and Azimuth Racking Systems
Adjustable tilt and azimuth racking systems, such as IronRidge’s XR100, offer flexibility and adaptability in tracking the sun’s movement. These systems typically feature a central pivot point that allows for adjustments to be made in both tilt and azimuth, maximizing energy production throughout the day. For example, a 10 kW solar array with a 2:1 slope and 30° tilt may benefit from an adjustable racking system that can accommodate seasonal changes in sun angle.
Top Brands and System Components
Top racking system manufacturers offer a range of components and accessories designed to simplify installation and enhance system performance. For example, Unirac’s Trak Mount system features a patented rail-based design that allows for easy adjustments and a high degree of precision. Schletter’s Ground Mount system is designed for larger commercial and utility-scale installations, with a focus on high strength-to-weight ratios and durable construction. When selecting a racking system, consider the specific needs and requirements of your project, and choose a system that meets or exceeds local building codes and industry standards.
