Title (EN) SOLAR ENERGY UTILIZATION SYSTEMS AND METHODS
(FR) SYSTÈMES ET PROCÉDÉS D'UTILISATION DE L'ÉNERGIE SOLAIRE
Abstract:
(EN) In a concentrated solar photoelectric system, at least one controllable radiation attenuation element (e.g., an array of controllable pixels or segments) is arranged to selectively attenuate transmission of radiation to a photoelectric element (e.g., a solar panel). Liquid crystals may provide attenuation utility without necessity for mechanical actuation. Attenuation may be controlled responsive to at least one sensor to maintain each portion of the photoelectric element at or below a maximum power conversion point. Non-planar attenuators and/or lenses may be provided. One or more thermal exchange fluid channels may be in thermal communication with the thermoelectric element.
(FR) Dans un système photoélectrique solaire concentré, au moins un élément commandable d'atténuation de rayonnement (par exemple, un réseau de pixels ou segments commandables) est agencé pour atténuer sélectivement une transmission de rayonnement à un élément photoélectrique (par exemple, un panneau solaire). Des cristaux liquides peuvent permettre un effet d'atténuation sans nécessiter un actionnement mécanique. L'atténuation peut être commandée en réponse à au moins un détecteur pour maintenir chaque partie de l'élément photoélectrique au niveau de ou en dessous d'un point de conversion de puissance maximal. Des atténuateurs non plans et/ou des lentilles peuvent être prévus. Un ou plusieurs canaux de fluide d'échange thermique peuvent être en communication thermique avec l'élément thermoélectrique.
