Abstract: A testing platform tests an electrical and mechanical system such as an HVAC unit according to an algorithm that reduces the total testing time of the components of the system, while ensuring the safety of the system during system-wide testing. The platform uses constraints that are checked both before and during the testing to ensure that HVAC operating conditions are acceptable for starting and maintaining component tests. Preferably, the platform uses finite-state machines for each device to organize the component tests, allowing for monitoring of constraints and starting, pausing, and stopping component tests. Preferably, total test execution time is reduced by running component tests in parallel, running component tests based on loads of the components, or combinations of both.

Abstract: In an example, the present invention provides a solar tracker apparatus. In an example, the apparatus comprises a center of mass with an adjustable hanger assembly configured with a clam shell clamp assembly on the adjustable hanger assembly and a cylindrical torque tube comprising a plurality of torque tubes configured together in a continuous length from a first end to a second end such that the center of mass is aligned with a center of rotation of the cylindrical torque tubes to reduce a load of a drive motor operably coupled to the cylindrical torque tube. Further details of the present example, among others, can be found throughout the present specification and more particularly below.

Abstract: A solar module mounting bracket assembly includes a rail configured to support a solar module thereon, and a pair of braces. The braces each have a first end portion movably coupled to the rail. The braces are movable relative to the rail between a collapsed configuration and an expanded configuration. In the expanded configuration, the braces cooperatively define a channel dimensioned for receipt of a frame member.

Abstract: A method and system for cleaning an array of solar panels. The system can include an applicator apparatus configured with a plurality of cleaning devices, and an automatic position system (APS) configured with the applicator apparatus. The APS can include a first and second sensor coupled to the applicator apparatus. A controller coupled to the first and second sensor devices can be configured to adjust a position of the applicator apparatus to maintain the plurality of cleaning devices in a direction facing a solar panel to facilitate a removal of an undesired material from the solar panel, while the applicator apparatus is moved from a first position to a second position. A mobile vehicle can he configured with the applicator apparatus to move along a row of the array of solar panels to perform the method for cleaning.

Abstract: Methods and systems of managing dynamic response to wind in a solar tracker system are provided. The method includes determining a wind speed, comparing the wind speed to a predetermined threshold value to determine if the wind speed equals or exceeds the predetermined threshold, positioning a windward most solar tracker to a predetermined angle based on the comparing, and positioning a leeward most solar tracker to the predetermined angle based on the comparing. The solar trackers are positioned at the predetermined angle at a predetermined interval starting at the windward most solar tracker and the remaining solar trackers remain in a normal operating condition.

Abstract: A solar tracking system is provided and includes a solar array, a support structure configured to support the solar array, a base configured to rotatably support the support structure, and an articulation system configured to articulate the support structure relative to the base. The articulation system includes a gearbox that is coupled to the support structure and an actuator that is configured to extend and retract. The actuator includes a first end portion and a second, opposite end portion, wherein the first end portion is rotatably coupled to the base and the second end portion is coupled to the gearbox. Extension of the actuator causes the support structure to rotate about the base in a first direction and retraction of the actuator causes the support structure to rotate about the based in a second, opposite direction.
