Abstract: A roof-based system for suspending photovoltaic modules, such as solar panels, relative to a roof surface without penetration of the roof surface. Cables under tension span the roof surface, with opposed ends of the cables securely mounted to generally C-shaped cable arm assemblies that wrap around the roof edge for connection via pivot joint assemblies to the underside of an overhanging eave, the immediate side wall of the structure below the roof, or directly to roof edge fascia. The system is completely contained to the roof area with no penetration of any parts through the roof surface. Vertical and horizontal rails set upon the roof surface, but not attached to the roof surface, support the weight of the photovoltaic modules attached thereto, while the cables, under tension, hold down the rails in position relative to the roof surface.

Abstract: A system of suspended photovoltaic modules relative to a surface wherein modules are suspended generally parallel and spaced apart along the length of dual pairs of catenary cables. A hanger assembly permits initial attachment of a module during installation as the cables are mounted to the rear surfaces of the modules via mid clamp assemblies. End clamp assemblies attach the modules to the cables proximate stanchions having two spaced posts joined by cross beams, a top cross beam angled to define an inclined plane. The respective pairs of cables supporting the modules are joined with cable cross ties to form a catenary shape. The modules may be suspended in a generally consistent inclined plane or a slightly concave curve. The catenary cables and clips are sized and shaped to allow the modules limited sway movement as necessary to reduce stresses and forces during wind or other adverse weather events.
