Abstract: A universal solar module mounting system includes a plurality of vertical posts and a plurality of parallel and horizontal beams. Each of the beams is supported above the ground by one or more of the posts. Purlins are coupled to the beams with purlin clips and fasteners. The purlin clips or beams can include parallel and adjacent slots. Fasteners are placed through the slots and the slots allow the purlins to be positioned on the beams to properly support the specific solar modules being used. Mounting components are used to secure each of the solar modules to two or more of the purlins.
