Abstract: A Modular Roof Mounting System utilizes an assembly Jig that makes assembly of the structural units very easy and repeatable. The assembly Jig incorporates a photovoltaic panel mounting frame that the structure is required to support. In addition to the photovoltaic panel mounting frame it includes only two low cost universal components: two South rail locators and two North rail locators. The North and South rail locators are attached to the mounting holes in the panel frame, two on the South edge and two on the North, and produce a rail spacing that lines up with the same holes. The North Rail Locators have additional locating features to position the cross beams. Using a photovoltaic panel mounting frame to create a Jig that automatically determines the configuration of the Precision-Modular assembly and requires no adjustments and allows for the assembly of mounting structures for various photovoltaic panel geometries.
