Linear concentration solar installation for converting solar energy into thermal energy used to produce electricity, has flexible thermally insulating material rested on upper part of outer rigid wall to maintain reflective wall in position

摘要

The installation has a primary reflector to reflect and concentrate solar radiation to a receiver. A trough shaped secondary reflector (8) has a outer rigid wall (11) with coplanar inner edges (12) ended in end parts (13) that are folded at right angle towards an upper part of the wall. An inner reflective wall (10) reflects solar radiation to a receiving tube (5) and rests on the end parts by S curved end parts (16). A flexible thermally insulating material (19) fills a space between the walls and rests on the upper part to maintain the reflective wall in position relative to the rigid wall.
