PANEL HAVING LONGITUDINAL MIRRORS FOR A SOLAR POWER PLANT

The invention relates to a solar power plant having mirrors (7) and horizontal longitudinal panels (1), whose turn axes and axes of symmetry (14) are parallel to the long axis of the solar panel, which consists of a balanced expansion and pressure collector, the tubes (19) of which are grouped in independent central (20) and adjacent (21 and 22) bundles, thermally isolated from each other longitudinally, the heating fluid circulating first through both adjacent bundles in parallel, to be subsequently injected into the central bundle, wherein the intensity of the solar radiation collected is greater owing to the solar radiation collected from the array of mirrors focused on the mid-line of the active side (2) of the panel; each bundle of tubes may be covered by a separate (60, 61, 62), transparent window (28).
