Abstract: The present invention relates to a reflective element for solar fields, having a sandwich-type structure, comprising a reflective sheet (1), a reinforcement sheet (2) and a layer of foam (3) arranged between the reflective sheet (1) and the reinforcement sheet (2).

Abstract: Reflector element (1) for a solar collector including a not mechanically flexed monolithic glass pane (2) of heat treated glass which due to its enhanced resistance properties becomes self-supported without requiring the presence of any kind of frame member or device to maintain its shape at the normal utilization temperatures. The reflector element is substantially parabolic and can be provided with at least one bore (3) for a fixing element to fix the reflector element (1) to a supporting structure.

Abstract: The present invention relates to a system for the articulated attachment between a reflector element used in a solar thermal concentration collector and its supporting structure. The system allows the attachment between the reflector mirror and the supporting structure in all its anchoring points without there being stresses of any type due to angular deviations on the reflector. It comprises a main body of attachment (2) intended for being fixed on the face of the reflector element (13) opposite the face of incidence of solar radiation, comprising a hole (14) intended for receiving a male fixing element (3), and adaptable joint means which allow the free rotation in space of the attachment between the reflector element (13) and the supporting structure.

Abstract: The present invention relates to a protection for reflective mirrors of solar energy concentrators. The protection comprises a peripheral cord which extends along the edge of the reflector covering the peripheral area of the reflective layer on the edge of the reflector. Preferably, the peripheral cord is made substantially of an elastomer (silicone) polymer and adheres to at least the edge of the reflective mirror to protect it from corrosion and blows. It additionally defines a method to protect a reflector against corrosion and blows by means of the extrusion of a peripheral cord on the edge of the reflective mirror.
