摘要： In an example, the present invention provides a solar tracker apparatus configured with an off-set drive assembly. In an example, the apparatus has an inner race structure, which has a cylindrical region coupled to a main body region, the main body comprising an off-set open region. The cylindrical region is an annular sleeve structure coupled to the main body region, which occupies the spatial region within the cylindrical region. In an example, the apparatus has an outer race structure coupled to enclose the inner race structure, configured to couple the inner race structure to allow the inner race structure to move in a rotational manner about a spatial arc region; and configured to allow the inner race structure to pivot about a region normal to a direction of the spatial arc region. In an example, the solar tracker has a clamp assembly that is configured to pivot a torque tube.

摘要： In an example, the solar tracker has a clamp assembly that is configured to pivot a torque tube. In an example, the assembly has a support structure configured as a frame having configured by a first anchoring region and a second anchoring region. In an example, the support structure is configured from a thickness of metal material. In an example, the support structure is configured in an upright manner, and has a major plane region. In an example, the assembly has a pivot device configured on the support structure and a torque tube suspending on the pivot device and aligned within an opening of the support and configured to be normal to the plane region. In an example, the torque tube is configured on the pivot device to move about an arc in a first direction or in a second direction such that the first direction is in a direction opposite to the second direction.

摘要： A solar tracker apparatus includes an adjustable hanger assembly that has a clam shell hanger assembly. The clam shell hanger assembly may hold a torque tube comprising a plurality of torque tubes configured together in a continuous length from a first end to a second end. A center of mass of the solar tracker apparatus may be aligned with a center of rotation of the torque tubes, in order to reduce a load of a drive device operably coupled to the torque tube. Solar modules may be coupled to the torque tubes. The solar tracker includes an energy system that includes solar panel, a DC to DC converter, a battery, and a micro-controller. The energy system may facilitate full operation movement of the tracker apparatus without any external power lines.

摘要： In an example, a clamp assembly for a glass on glass solar module for a tracker is included. The assembly has a lower clamp structure characterized by a top-hat shaped rail structure having a length extending from a first end to a second end. In an example, the assembly has an upper clamp structure configured to sandwich a pair of edges of a pair of solar modules with a portion of the lower clamp structure. In an example, the assembly has a locking spacer configured to the pair of edges of the pair of solar modules. In an example, the pair of edges comprises substantially glass material. In an example, the assembly has a pair of key structures configured with the locking spacer. Each of the key structures is affixed to each of the solar modules to physically lock each of the solar modules to the upper clamp structure.
