Self-ballasting solar array mount

摘要

A solar panel installation includes a number of solar panels supported by two or more beams that are arranged parallel to each other on the surface of a roof. Each panel is arranged across and supported by multiple ones of the beams. The combined weight of the beams at least equals the combined weight of the panels, which permits the use of panels that are lighter and easier to handle than ones whose weight forms the bulk of the ballast. For example, the beams advantageously can have about twice as much combined weight as the combined weight of the panels. Various aspects and variations are also disclosed.
