Abstract: A method for controlling the orientation of a single-axis solar tracker orientable about an axis of rotation, including observing the evolution over time of the cloud coverage above the solar tracker; determining the evolution over time of an optimum inclination angle of the solar tracker substantially corresponding to a maximum of solar radiation on the solar tracker, depending on the observed cloud coverage; predicting the future evolution of the cloud coverage based on the observed prior evolution of the cloud coverage; calculating the future evolution of the optimum inclination angle according to the prediction of the future evolution of the cloud coverage; servo-controlling the orientation of the solar tracker according to the prior evolution of the optimum inclination angle and depending on the future evolution of the optimum inclination angle.

Abstract: A method for controlling the orientation of a single-axis solar tracker (1) orientable about an axis of rotation (A), said method repetitively completing successive control phases, where each control phase implements the following successive steps:
a) observing the cloud coverage above the solar tracker (1);
b) comparing the observed cloud coverage with cloud coverage models stored in a database, each cloud coverage model being associated to an orientation setpoint value of the solar tracker;
c) matching the observed cloud coverage with a cloud coverage model;
d) servo-controlling the orientation of the solar tracker by applying the orientation setpoint value associated to said cloud coverage model retained during step c).
The present invention finds application in the field of solar trackers.-
