A parabolic primary mirror (10) has a concave specular surface (12) that is constructed and positioned to receive solar energy and focus it towards a focal point. A secondary mirror (14) having a convex specular surface (16) is constructed and positioned to receive focused solar energy from the primary mirror and focus it onto an annular receiver (18). The annular receiver (18) may include an annular array of optical elements (100) constructed to receive solar energy from the secondary specular surface (14) and focus it onto a ring of discreet areas. A ring of solar-toelectrical conversion units are positioned on the ring of discreet areas. A sun sensor that allows accurate solar tracking to keep mirror system aligned with the sun.

L'invention concerne un miroir primaire parabolique (10) ayant une surface spéculaire concave (12) qui est construit et positionné pour recevoir de l'énergie solaire et la diriger vers un point focal. Un miroir secondaire (14) ayant une surface spéculaire convexe (16) est construit et positionné pour recevoir l'énergie solaire dirigée du miroir primaire et la diriger sur un récepteur annulaire (18). Le récepteur annulaire (18) peut comprendre un réseau annulaire d'éléments optiques (100) construit pour recevoir l'énergie solaire de la surface spéculaire secondaire (14) et la diriger sur un anneau de zones discrètes. Un anneau d'unités de conversion solaire-électrique est positionné sur l'anneau de zones discrètes. Un capteur solaire permet un suivi solaire précis pour maintenir le système de miroir aligné avec le soleil.
