Abstract: An improved solar panel assembly is provided. The assembly includes a plurality of sub-assemblies which are spaced from one another. Each sub-assembly has at least two torque tubes and a plurality of laterally spaced rails which are coupled with the torque tubes for supporting a plurality of solar panels or reflectors thereon. Rotation of the torque tubes about the lateral axis rotates the solar panels or the reflectors mounted on the rails. At least one torque arm is joined with and extends transversely away from one of the torque tubes of each sub-assembly. A driveshaft extends longitudinally between the sub-assemblies and is moveable in the longitudinal direction for rotating the solar panels or reflectors via the torque arms, the torque tubes and the rails. The torque tubes are generally cylindrical in shape and adjacent torque tubes of each sub-assembly are co-axially joined in an end-to-end relationship with one another.

Abstract: A single axis solar tracker assembly for supporting and controllably rotating a plurality of solar panels is provided. The solar tracker assembly includes a plurality of sub-assemblies which are spaced from one another in a first direction and are operably coupled with a driveshaft that is moveable in the first direction. Each sub-assembly includes at least one torque tube which extends in a second direction and torque arm which is operably coupled with the at least one torque tube. Each sub-assembly further includes a connector which operably connects the torque arm with the driveshaft for rotating the at least one torque tube in response to movement of the driveshaft in the first direction. The connector is pivotably coupled with the torque arm and non-pivotably coupled with the driveshaft and extends in a vertical direction to provide for an increased vertical distance between the torque arm and the driveshaft.

Abstract: The specification describes a composition curable by high-energy radiation in the presence of oxygen which contains conventional monomers, oligomers and/or polymers curable by high-energy radiation besides minor amounts of a natural wax, a solvent extraction product of a natural wax, a wax alcohol, a wax ester and/or a wax carboxylic acid. The specification also describes the preparation of said composition and the use thereof in the formation of coatings.
