Abstract: Transportable linear fresnel solar system in a merchandise container comprising a series of rows of reflective mirrors (6), an automatic cleaning system (10), a linear receiver (18) and a support structure designed to be mounted on a merchandise container commercial (1). The support structure in turn comprises two folding side platforms (2) capable of acquiring two fixed positions, one vertical, where all the elements of the platform are within the volume of the container structure, allowing it to be transported and / or stored using conventional methods, and another horizontal one that allows the system to operate as a conventional linear linear solar collector. On the folding side platforms (2), the rows of reflecting mirrors (6) are mounted on mirror-holder benches (7) and at least two ballast tanks (11) used as overweight to reduce the necessary foundation. The automatic cleaning system (10) comprises travel rails (12) through which central stiffeners (16) are moved. Together with these central stiffeners (16) there is at least one cleaning unit (15) for each row of mirrors (6). The cleaning units (15) in turn comprise an element made of absorbent materials (13), a top cover (14) and a water supply system. The linear receiver (18) comprises an external housing (4), end brackets (3) and intermediate brackets (5). The outer shell (4) in turn comprises a transparent cover (23), an insulation (21), a secondary reflective surface (22) and at least one tubular receiver (9).
