method to control the orientation of a solar tracker, control method and solar tracker

摘要

The invention relates to a method for controlling the orientation of a single axis solar tracker (1) which can be oriented around a rotation axis (a), wherein successive control phases can be conducted in a manner. repeated. According to the invention, the following successive steps are performed in each control phase: a) observe the cloud cover over the solar tracker (1); b) compare observed cloud coverage with cloud coverage models stored in a database, where each cloud coverage model is associated with an orientation setpoint value for the solar tracker; c) correlate observed cloud coverage with a cloud coverage model; and d) controlling the orientation of the solar tracker by applying the orientation setpoint value of the cloud cover model selected in step c). The present invention is suitable for use in the field of solar trackers.
