Abstract: Solar array (1) comprising solar modules (3) distributed in rows (10), each solar module comprising solar collector (5) carried by a single-axis solar tracker (4), a reference solar power plant (2) comprising a central reference solar module and at least one secondary reference solar module, and a piloting unit (7) adapted for: piloting the angular orientation of the central reference module according to a central reference orientation setpoint corresponding to an initial orientation setpoint, piloting the orientation of each secondary reference module according to a secondary reference orientation setpoint corresponding to the initial orientation setpoint shifted by a predefined offset angle; receiving an energy production value from each reference module; piloting the orientation of the modules, except for the reference modules, by applying the reference orientation setpoint associated to the reference module having the highest production value.

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.
