Abstract

A system may include determination of power delivered to an intended load by a solar collector and determination of a solar tracking error of the solar collector based on the determined power. Some aspects include determination of a servo feedback signal based on the determined power, wherein determination of the solar tracking error includes determination of the solar tracking error based on the servo feedback signal. Determination of the solar tracking error may further include determination of the solar tracking error based on the servo feedback signal and on a relationship between a response of the solar collector and tracking error.
