The first is an adjustable L-foot component. Made of extruded aluminum, these L-feet are strong enough for both residential and commercial solar PV module installations. The vertical slots make it easy to level the PV array when there are irregularities in the roof. When increased airflow or roof flashing is required, IronRidge offers two different types of standoffs. Lightweight aluminum standoffs are available for flush mount solar PV module applications, Heavy-duty, welded steel standoffs are available for tilt mount solar mounting applications. These standoffs support common flashing products such as those from Oatey. In addition, the IronRidge standoffs are available in multiple heights. Tilt leg attachments are available for solar PV projects where installers wish to optimize power by tilting solar PV modules more directly at the sun. These extruded aluminum legs attach quickly and directly to either the XRS or XRL solar PV rails. The well thought-out and simple design enables adjustability in all three dimensions. The IronRidge tilt legs come in a variety of lengths to cover a wide range of desired tilt angles.
