Abstract: The invention relates to a linear Fresnel solar power system that can be transported in a goods container, comprising a series of rows of reflective mirrors (6), an automatic cleaning system (10), a linear receptor (18) and a support structure designed to be mounted on a commercial goods container (1). The support structure comprises two foldable lateral platforms (2) which can assume two fixed positions: one vertical position where all the elements of the platform remain inside the volume of the structure of the container, permitting same to be transported and/or stored using conventional methods; and another horizontal position that permits the system to operate as a conventional linear Fresnel solar collector. The rows of reflective mirrors (6), mounted on mirror-carrying banks (7), and at least two ballast tanks (11), used as excess weight to reduce the necessary foundation, are provided on the foldable lateral platforms (2). The automatic cleaning system (10) comprises movement rails (12) via which central stiffeners (16) are transferred. At least one cleaning unit (15) for every row of mirrors (6) is joined to these central stiffeners (16). The cleaning units (15) comprise an element (13) formed by absorbent materials, an upper cover (14) and a water supply system. The linear receptor (18) comprises an external casing (4), end supports (3) and intermediate supports (5). The external casing (4) comprises a transparent cover (23), an insulation means (21), a secondary reflective surface (22) and at least one tubular receptor (9).
