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.
