An automated method causes a terrestrial solar cell array to track the sun. The solar cell system includes motors that adjust a position of the array along different respective axes with respect to the sun, wherein a first motor adjusts the inclination angle of the array relative to the surface of the earth and a second motor rotates the array about an axis substantially perpendicular to that surface. The method includes (a) using a software algorithm to predict a position of the sun at a future time; (b) using a computer model to determine respective positions for the motors corresponding to the solar cell array being substantially aligned with the sun at the future time; and (c) activating and operating the motors at respective particular speeds so that at the future time the solar cell array is substantially aligned with the sun. The future time may correspond to any time during operation. An initial future time may correspond to a start up time after sunrise at which point the solar cell is to begin tracking the sun.
