Solar-energy collector/concentrator with cassegrain-type optics

A solar energy collector/concentrator with Cassegrain-type optics, including at least one collector/concentrator unit comprising a primary concave reflector supported on a base body and arranged to reflect solar radiation, a secondary convex reflector supported by a substantially flat transparent panel above said primary reflector and arranged to reflect said solar radiation from the primary reflector, and a receiver unit arranged to receive the solar radiation reflected by said secondary reflector through a central opening formed in the primary reflector characterised in that the primary reflector is supported on a base body obtained by injection moulding, which defines a central support configured to support a region around said central opening of the primary reflector, a plurality of peripheral legs configured to support respective peripheral regions of the primary reflector and first integral connection members connecting said peripheral legs with said central support, the peripheral legs having bottom ends configured to lean on a substantially flat supporting surface and top ends located above said peripheral regions of the primary reflector and configured to be in contact with said transparent panel.
