NOVELTY - Adjusting a photovoltaic solar cell array of terrestrial solar cell system that tracks the sun, comprises: (a) predicting position of sun using software algorithm during course of day based, at least in part, on latitude, longitude and elevation; (b) determining respective actuations using computer model, for motors corresponding to solar cell array which is aligned with sun during course of day; and (c) sampling output parameter of the solar cell array at predetermined times, and adjusting the position of the solar cell array so that solar cell array is more accurately aligned with the sun.    USE - The method is useful: for adjusting a photovoltaic solar cell array of a terrestrial solar cell system that tracks the sun (claimed); and for finding the sun for solar tracking.    ADVANTAGE - The method: adjusts the array which is orthogonal to the incoming rays of the sun, and maximizes the power generation, and optimizes the amount of sunlight impinging upon the cells; executes an alignment routine on a continuous basis which inherently compensates for such slowly varying decreases in optimum measurement; executes the routine with a high enough periodicity; and accurately aligns the solar cell array with the sun.    DETAILED DESCRIPTION - Adjusting a photovoltaic solar cell array of a terrestrial solar cell system that tracks the sun, comprises: predicting a position of the sun using a software algorithm during the course of the day based, at least in part, on latitude, longitude and elevation; determining respective actuations using a computer model, for the motors corresponding to the solar cell array which is aligned with the sun during the course of the day; and sampling an output parameter of the solar cell array at predetermined times, and adjusting the position of the solar cell array so that the solar cell array is more accurately aligned with the sun, where the system comprising two motors each of which is operable to adjust a position of the array along a different respective axis with respect to the sun.
