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 solar module including a single-axis solar tracker orientable about an axis of rotation, and a photovoltaic device supported by said tracker and having upper and lower photoactive faces, including: measurement of a distribution of the solar luminance called incident luminance originating from the incident solar radiation coming from the sky to reach the upper face, said distribution being established according to several elevation angles; measurement of a distribution of the solar luminance called reflected luminance originating from the albedo solar radiation corresponding to the reflection of the solar radiation on the ground to reach the lower face, said distribution being established according to several elevation angles; determination of an optimum orientation considering the measurements of said distributions of the incident and reflected solar luminance; servo-control of the orientation of the module on said optimum orientation.

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.-
