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: A solar power plant includes a solar tracker supporting solar modules with the solar tracker supported on a first end by a first pier and on a second end by a second pier. A drive device is coupled to the solar tracker and configured to rotate the solar tracker about an axis. An energy storage unit is supported by the solar tracker between the first pier and the second pier with the energy storage unit configured to power the drive device. The solar tracker also includes a controller in communication with a memory with the memory storing instructions thereon that when executed by the controller, cause the controller to: receive forecast data for the solar power plant; determine, based on the forecast data, a diffuse angle adjustment; and output a signal to the drive device to rotate the solar tracker to a desired angle based on the diffuse angle adjustment.

Abstract: A solar tracking system comprises multiple solar panel modules forming a grid of solar panel modules, wherein the multiple solar panel modules are movable relative to a solar source independently of each other; and a control system configured to orient each of the multiple solar panel modules to the solar source independently of each other based on a performance model to optimize an energy output from the grid of solar panel modules, wherein the performance model predicts an energy output from the grid of solar panel modules based on a topography of the area containing the grid of solar panel modules and weather conditions local to each of the solar panel modules.
