Abstract: A node for a solar frame including an elongate portion having a channel extending through it in which a structural element is disposed or a solid elongate portion on to which a structural element is disposed. The node comprises a fin extending radially outward from the elongate portion where at least 5% of the volume of the fin is replaced by at least a single void extending essentially in parallel with the channel or the extrusion direction of the solid elongate portion. An apparatus for transmitting torque in a solar frame having structural elements and a support. A system for solar mirrors. A node for a solar frame. A method for connecting a structural element with a strut having a strut end piece of a solar mirror support frame. A method for producing a node for solar mirror frame.

Abstract: A connector includes a first body, a second body, a first fastener, and a second fastener. The first body has a base portion and a protrusion, the protrusion extends away from the base portion along a first direction, and the first body has a first cavity that extends into the protrusion and towards the base portion along the first direction. The second body has a second cavity, which is shaped to receive the protrusion such that rotation of the first body relative to the second body is blocked. The connector may be used to attach structural members, for example during the construction of a modular structure.

Abstract: An apparatus for transferring force to a frame of a solar mirror array. The frame has at least one structural element. The apparatus includes a torque plate. The apparatus includes at least one node attached to and in contact with the plate which connects with the structural element. An apparatus for attaching a primary solar mirror frame array with a secondary mirror frame array. A solar trough frame for holding solar mirrors.

Abstract: A method for producing a node for solar mirror frame having the steps of placing an aluminum billet having a diameter of less than 13 inches into a die. There is the step of extruding the billet through the die so an extrusion is formed having an elongate portion to which a structural element is attached, and a fin extending radially outward from the elongate portion where at least 5% of the volume of the fin is replaced by at least a single void extending essentially in parallel with the elongate portion, the elongate portion and the fin having a circle diameter of less than 12 inches; and cutting the extrusion to form the node.
