K2 Systems

Tough Solar Mounts for Faster Installations

Finding a solar mounting setup that balances heavy-duty support with fast, painless installation can be a challenge. What drives this exceptional capability across thousands of jobsites globally? The secret lies in the K2 Systems design choice of combining strong, wind-tunnel-tested aluminum parts with smart, modular hardware that snaps together with fewer tools. This straightforward structural choice means better hold on the roof, much shorter installation times for work crews, and an uncompromising level of safety that protects your property for decades.

With a proven global track record of over 36 gigawatts of installed hardware across 130 countries, these German-developed solar racking systems are built to handle extreme wind and heavy snow loads. The collection features versatile solutions including the SingleRail and SolidRail series for pitched tile roofs, the simple Dome 6 series for flat roofs, and the compact MiniRail system made specifically for metal roofs. Whether you are setting up a residential rooftop or a large commercial array, you can use our convenient left-side filters to sort by your specific roof type and find the exact K2 Systems parts required for your project grid below.
