Abstract: A solar panel support includes a plastic body, having front, back, bottom, and side walls defining a hollow box-like shape. The front wall is lower than the back wall. Side walls include upper side edges sloping from the back wall to the front wall. A ledge extends from the bottom, side, front, and back walls, and an upstanding flange around the ledge is generally L-shape in section. The side walls include a plurality of removable access portions that when open enable passing of electrical services therethrough. The back and front walls each include a plurality of a generally wedge-shaped depressions. Each side wall includes a rectangular depression surrounding the removable portions and a generally right-angular abutment is formed at a junction between each side wall and the back wall and the front wall. The bottom wall includes a plurality of generally circular depression formations.

Abstract: A truss reinforcing retrofit kit and method for strengthening an existing roof structure. The kit includes a tensile member, two couplings attached to the ends of the tensile member, and a king post tensioning system. The tensile member is coupled to the ends of the roof structure using the couplings. The king post tensioning system is positioned between the roof structure and the middle of the tensile member. Tension is increased within the tensile member so as to put the tensile member and the king post tensioning system under strain when there is an additional load on the roof structure in addition to a pre-existing dead load. For example, the additional load may be caused by one or more solar panels mounted on the roof structure. Alternatively, the tension might put the tensile member and the king post tensioning system under strain when the roof structure is subject only to the pre-existing dead load.

Abstract: A solar panel support system, having extruded thermo plastic rails, with channels formed along such rails, mounting legs of thermo plastic or metal, and attachment devices for attaching the mounting legs to the channels in the rails.

Abstract: A solar panel support formed of a single integral one piece moulded plastic body, having a bottom wall, two side walls and front and back walls, defining a hollow open topped box-like shape, the front wall being lower and the back wall higher, and the two side wall upper side edges sloping from the back wall down to the front wall, a ledge extending out from the walls, and an upstanding flange around the ledge defining a generally L-shape in section, a plurality of removable access portions in each side wall, for opening the same to pass electrical services there through, a plurality of a generally wedge shaped depressions in the back wall, a plurality of generally wedge shaped depressions in the front wall, a rectangular depression in each side wall, surrounding the removable portions, a generally right angular abutment formed at the junction between each of side wall and the back wall and the front wall, a plurality of generally circular depression formations in the bottom wall, a pair of parallel depressio
