One or more embodiments of a system including a laser emitting device and a target is disclosed. The laser emitting device includes a connector configured to connect to a device having a flat top extending in a first plane and a flat side extending in a second plane, and a laser emitter connected to the connector such that when the connector is connected to the device, the laser emitter is configured to emit a laser in a first direction parallel to the first plane and the second plane. The target includes a body, a tray including at least one slit in a front side of the tray configured to allow passage of the laser into the tray, a neck connecting the body to the tray, and legs connected to the body and configured to support the body, neck, and tray.

A truss foundation for supporting single-axis solar tracker drive motors and center structures. An adapter joins a pair of adjacent truss legs and provides a mounting platform to support a drive motor and/or center structure of a solar tracker. The adapter has a pair of connecting portions that are received in the legs of the truss foundation. The adapter may be a unitary structure or consist of a pair of slidably connected members that are joined with fasteners to accommodate truss legs spaced apart at different distances.

A device includes a support structure having a plurality of concentric cuts through the support structure that define a set of structure sections. The device also includes an insert assembly supported by the support structure at an inner structure section of the set of structure sections. The inner structure section is configured to tilt the insert assembly at a tilt angle in accordance with a displacement of a first outer structure section of the set of structure sections.

A solar tracker bearing assembly has a rotating element sandwiched between two mounting brackets and held together by fasteners. The rotating element includes an arc-shaped slot such that the rotating element can pivot against the fixed mounting brackets. Bearings may be positioned within the arc-shaped slot. The rotating element can be configured to accept toque tubes of various cross-sections.

A tracking system for performing a movement control of a solar panel is provided, having a single axis solar tracking solution allowing an individual actuation of a solar panel and its respective rotation axis. The tracking system is applied in an individual solar panel, and has a local control unit, an electrical motor, a tracking actuator mechanism, a blockage unit and a tracking support mechanism, which is useful for solar power plant installations where individual panel tracking is an advantage due to site conditions such as irregular grounds or unstable locations as in aquatic sites or locations with variable slopes.
