Abstract: A solar panel support system comprising a plurality of solar panels supportingly engaged with and connected to ledges of U-shaped weighted support pans of different heights. The ledges are perforated with at least two threaded apertures wherein edges of adjacent slightly spaced apart solar panels supported on a ledge of a support pan are spanned by an apertured hold down element. One of the threaded apertures is accessible, through a spacing between the slightly spaced apart solar panels, to a bolt which passes through the hold down element and into threaded engagement with the one of the threaded apertures with hold down engagement of the adjacent panels to a ledge of the pan being effected with the threaded engagement of the bolt and the threaded aperture.
