Why Most Commercial Solar Fails the Roof
Most solar panel installations outlast the roof they sit on. In some cases, they void the warranty on day one. Custom Solar Solutions was born at the intersection of master-roofing and electrical innovation to solve this specific problem that industrial buildings often face.
The Integrated Industrial Solar Framing System
SWIF Racks are the only solar panel system designed specifically for Duro-Last roofing. The non-penetrating, heat-welded attachment method is the ideal installation technique for commercial roofs to avoid warranty issues and ensure an installation that passes the test of time. SWIF Rack bridges the gap between solar panel installation and commercial roof performance, enabling necessary maintenance and mitigating common issues that traditional solar panel installations can cause for commercial roofing.
The Benefits
SWIF Rack Installation on a Duro-Last Facility

Using the SWIF Rack solution, the Duro-Last facility is able to create enough energy output to power 100% of its operations.

SWIF Racks are constructed and installed with longevity in mind. These solar panels are built to withstand weight, harsh weather, and time.

Our Racks are installed securely by attaching panel rack legs to the roof trusses. This ensures that the solar panels are fixed to the roof, making the panels a permanent addition to the building.

SWIF Racks elevate solar panels and provide space for mounting electrical panels, effectively doubling the use of the racks.

The Duro-Last facility located in Grants Pass, Oregon, is a real-world example of how the revolutionary SWIF Rack System changes industrial roofing for the better.

By installing these racks, the Duro-Last manufacturing plant can avoid mold-growth that often occurs with typical solar panel installations, as pictured here.
