Abstract: Mixed heliostat field combining, in the same field, heliostats of different sizes and/or with different types of facets, all of them having at least one facet and being canted or not, and either having spherical, cylindrical, flat or quasi-flat (spherical with a high curvature radius) facets, such that the solar field is optimised in order to minimise shadows and blockages between heliostats, as a result of correct positioning of the heliostats in the field.

Abstract: Solar tracker with azimuthal rotation mechanism arranged on the upper extremity of the pedestal (1), comprising a fixed base (10), a hollow bearing cap (3) to support the supporting structure on the fixed base (10), a rotating mechanical element (17) arranged between the bearing cap (3) and the fixed base (10) and two hydraulic cylinders (6, 6?), arranged at different heights in relation to the vertical axis of the bearing cap (3) and, fixed at one end to the bearing cap (3) and at the other end connected by the same fixed axle (7), which is attached to the fixed base (10) in such a way that, when the pistons of the cylinders (6, 6?) begin to move, they cause the bearing cap (3) to which the cylinders (6, 6?) are attached, to rotate, thereby rotating the cylinders (6, 6?) relative to the same axle (7), which is fixed to the base (10).

Abstract: Solar tracker comprising a pedestal (1) upon which a structural support (10) is fixed for a reflective surface (15), which comprises: a fixed base (2) anchored to the floor, which comprises a flat upper surface (7) with an opening, a vertical axis mechanical rotation element (3) arranged in the opening of the flat surface (7) of the fixed base (2) and fixed to the pedestal (1) and an azimuthal rotation actuator cylinder (4) of the structural support (10), comprising a first end fixed to the floor by an anchoring means (16, 2) and a second end fixed to the mechanical rotation element (3) by fixation means, the mechanical rotation means being configured in such a way that when the actuator cylinder carries out its movement, the mechanical rotation element transmits the rotational movement of the second end of the actuator cylinder to the pedestal (1).
