Heliostat repositioning system and method

摘要

A system and method for providing real time control of a heliostat array or CPV/PV module that reduces actuation cost, the disclosure reduces the fixed cost of calibrating and repositioning an individual surface. This simultaneously removes the core engineering assumption that drives the development of large trackers, and enables a system and method to cost effectively track a small surface. In addition to lower initial capital cost, a small heliostat or solar tracker can be pre-assembled, mass-produced, and shipped more easily. Smaller mechanisms can also be installed with simple hand tools and do not require installers to rent expensive cranes or installation equipment.

1. A system for controlling multiple solar surfaces comprising: a track for setting a pre-determined path; a first solar surface of the multiple solar surfaces having a coupling gear; a second solar surface of the multiple solar surfaces having a coupling gear; a first support structure adjacent to a first portion of the track and operable to adjust an orientation of the first solar surface, and a second support structure adjacent to a second portion of the track and operable to adiust an orientation of the second solar surface, each support structure having: a shaft coupled to the corresponding solar surface and a first input gear, the first input gear configured to receive a first input to rotate said solar surface in a first direction, the coupling of the shaft and said solar surface configured to enable said solar surface to rotate in a second direction; and an outer structure enveloping the shaft and coupled to a second input gear and an output gear, the output gear configured to engage the coupling gear of said solar surface, the second input gear configured to receive a second input to rotate said solar surface in the second direction; and a robot including a drive system configured to position said robot along said track, the robot configured to engage input gears of the first support structure to modify the orientation of the first solar surface when the robot is positioned near said first position of said track, and to engage input gears of the second support structure to modify the orientation of the second solar surface when the robot is positioned near said second position of said track.
