<p>The device for capturing the solar energy comprises a set of solar sensors (2a,2b) laid out on the sensors support (3) which is mounted mobile on a chassis (4) and comprises means for following the Sun so that the sensors support is positioned substantially in the direction of the Sun. The device also comprises the control means (MCO) which determine the exact position of the sun at a given instant with respect to the reference position of the device, and the actuation means (MCA) designed to drive the sensors support (3) so to orientate its perpendicular axis (ZZ') in the direction determined by the control means (MCO). The control means (MCO) comprise a computer which allows to determine the position of the sun at a given instant as a function of input parameters related to the installation of the device, that is its geographic position (longitude, latitude), altitude, date and solar hour. The control means (MCO) are operated by the method of direct computing or by the method of table reading, in the first and second embodiments, respectively. The main support frame (3) is articulated on the intermediate frame (5) around a horizontal axis (XX'), and the intermediate frame (5) is articulated on the chassis (4) around a vertical axis (YY'). The actuation means (MCA) are connected to the displacement means (MD) which carry out the rotations of the frames (3,5). The control means (MCO) determine the exact angular positions of the Sun with respect to the orthogonal axes (XX',YY'). The control means (MCO) determine the position of the Sun with respect to the orthogonal axes (XX',YY'). The control means (MCO) determine the position of the Sun in real time and transmit the information to the actuation means (MCA) at adjustable time intervals. The device also comprises the inclination sensors designed to inform the actuation means (MCA) of the precise angular position of the sensors support (3) by the intermediary of an absolute coder (12).</p> |
