It can be used for the production of electricity, heating, air conditioning and desalination of water.

La présente invention décrit un panneau solaire à concentration et poursuite solaire 20 comprenant : Des réflecteurs mobiles avec poursuite solaire de section cylindro-parabolique placés parallèlement concentrent les rayons solaires vers une bande focale. Les réflecteurs peuvent être plat, recouverts de systèmes convergents vers la bande focale. The present invention discloses a solar concentrating and tracking solar panel comprising: Moving reflectors with parallel tracking of parallel parabolic section concentrate solar rays toward a focal band. The reflectors may be flat, covered with convergent systems to the focal band.

25 Un capteur fixe est placé dans la bande focale et permet la conversion de l'énergie solaire sous une ou plusieurs autres formes d'énergie. Le capteur peut être constitué de plusieurs capteurs de dimensions plus réduites. Le capteur peut être constitué d'un ou plusieurs dispositifs de concentration et d'un ou plusieurs capteurs plus petits. 30 Un système de suivi du soleil permet d'orienter les réflecteurs au moyen d'actionneurs pour avoir le meilleur rendement énergétique en sortie du capteur. Les actionneurs peuvent être électriques, pneumatiques ou hydrauliques. A fixed sensor is placed in the focal band and allows conversion of solar energy under one or more other forms of energy. The sensor may consist of several sensors of smaller dimensions. The sensor may consist of one or more concentration devices and one or more smaller sensors. A sun tracking system allows the reflectors to be oriented by means of actuators to have the best energy efficiency at the output of the sensor. The actuators can be electric, pneumatic or hydraulic.

Le panneau solaire peut être constitué d'une armature et de plusieurs ensembles comprenant des réflecteurs, un ou des capteurs, un ou des systèmes de suivi solaire. Un objectif de la présente invention est de réaliser des réflecteurs légers et précis au niveau de la bande focale ce qui permet de réduire la taille des capteurs, de réduire l'énergie nécessaire à la poursuite solaire et d'utiliser des actionneurs de poursuite solaire de faible encombrement et peu onéreux. 10 Un autre objectif est la miniaturisation de l'ensemble constitué par les réflecteurs, le système de poursuite solaire et du capteur dans un panneau solaire pour toiture de taille normale permettant de réduire significativement la surface de capteur nécessaire et ainsi améliorer l'efficacité du panneau solaire. 15 La miniaturisation et l'intégration dans un panneau solaire permet de limiter le besoin de nettoyage des réflecteurs et la maintenance. An armature supports the assembly consisting of the reflectors, the solar tracking system and the sensor. The armature may comprise an envelope at least partially transparent to the sun's rays on one of its faces. The solar panel may consist of an armature and several sets including reflectors, one or sensors, one or solar tracking systems. It is an object of the present invention to provide light and accurate reflectors at the focal length, thereby reducing the size of the sensors, reducing the energy required for solar tracking, and using solar tracking actuators. small footprint and inexpensive. Another objective is the miniaturization of the assembly consisting of the reflectors, the solar tracking system and the sensor in a solar panel for normal size roof to significantly reduce the sensor area needed and thus improve the efficiency of the panel solar. Miniaturization and integration into a solar panel limits the need for reflector cleaning and maintenance.
