Solar Bright 2.2m Aluminum Solar Mounting Rail Kit

Mounting rails are what your panels actually bolt onto, so getting the right profile and length matters as much as the panels themselves. At 2.2 meters, this rail suits standard residential panel rows, though you'll need to check that the rail profile matches your chosen mid clamps, end clamps, and roof attachment hardware. Since rail systems from different manufacturers aren't always interchangeable, confirm the exact aluminum alloy, wall thickness, and included hardware with the seller, and make sure your roof structure and attachment spacing can handle the expected wind loads in your area.
