摘要： The present invention concerns a device for collecting solar energy by means of a concentrator (12) of the nonimaging type and a receiver (3) for the transfer of energy by heat exchange with a fluid which operates, independently, a thermodynamic cycle for the exploitation of energy, said concentrator (12) comprising an inlet area (1), an underlying outlet area (2) and an inner space between said inlet area (1) and said outlet area (2); said receiver (3) being positioned under said concentrator (12) and said inner space of the concentrator (12) and said receiver (3) being connected by said outlet area (2), characterised in that said inner space of the concentrator (12) and said receiver (3) are in fluid communication through said outlet area (2), a plurality of solid particles (11) are present inside said receiver (3), and said device for collecting solar energy comprises means (6) apt to take a part of said solid particles (11) from said receiver (3) and to put them from below inside said inner space of said concentrator (12), said solid particles (11) subsequently returning, by gravity, into said receiver (3), passing through said outlet area (2).
