The subject matter described herein includes methods, systems, and computer readable media for controlling orientation of a photovoltaic collection system to track apparent movement of the sun. According to one aspect, a method for controlling orientation of a photovoltaic collection system to track apparent movement of the sun using a photovoltaic-collection-system-derived tracking algorithm is provided. The method includes determining an initial orientation of a photovoltaic collection system. The method further includes automatically deriving, using output from the photovoltaic collection system as it tracks apparent movement of the sun across the sky caused by spinning of the earth on its axis and its orbit around the sun, a tracking algorithm for controlling orientation of the photovoltaic collection system to track the apparent movement of the sun. The method further includes controlling orientation of the photovoltaic collection system to track apparent movement of the sun using the photovoltaic-collection-system-derived tracking algorithm.
