Abstract: The invention relates to a solar concentrator with a supporting and solar tracking system, which proposes a solar concentrator comprising one or several lenses and one or several collectors and at least two attachment structures (2) for attaching the collector solar and the lens and at least two fastening structures (1) which allow a rotation according to a longitudinal axis. The attachment structure can be rotated or displaced, allowing the displacement of the lens (3) and the collector (4) in opposite directions and the variation of their relative distance, which solves the problem of the variation of the focal distance for each individual angle of incidence of the radiation.
