Method for controlling the orientation of a solar tracker based on cartographic models

A controlling method for controlling an orientation of a single-axis solar tracker orientable about an axis of rotation, said controlling method repetitively completing successive control phases, wherein each control phase implements the following successive steps:

• a) observing a cloud coverage above the solar tracker to obtain an observed cloud coverage;
• 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 for 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).
