A method for controlling the orientation of a single-axis solar tracker orientable about an axis of rotation, the method repetitively completing successive control phases, where each control phase implements the following successive steps: observing the cloud coverage above the solar tracker; 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; matching the observed cloud coverage with a cloud coverage model; servo-controlling the orientation of the solar tracker by applying the orientation setpoint value associated to said cloud coverage model retained during step c).
