A method for controlling a photovoltaic (PV) panel in a PV system including a computing device that provides motor control signals and implements an iterative adaptive control (IAC) algorithm for adjusting an angle of the PV panel. The IAC algorithm relates P at a current time k (P(k)), an elevation angle of the PV panel at k (θS (k)), P after a next step (P(k+1)) and an elevation angle of the PV panel at k+1 (θS (k+1)). The algorithm generates a perturbed power value P(k+1) to provide a power perturbation to P(k), and calculatesθS (k+1) using P(k+1). The motor control signals cause the motor to position the PV panel to achieveθS (k+1). A change in P resulting from the positioning is compared to a predetermined change limit, and only if the change in P is≧the change limit, again sensing P, and repeating the generating, calculating and positioning.
