Problems solved by technology

The first disadvantage is that the available concentration of solar energy depends only on the size of the concave mirror, and in order to obtain a high level of concentration, a large surface mirror must be used
A second disadvantage of the known solution 2005 / 116534 is that in order to change the azimuthal orientation, the supporting structure of the generator has to be turned around a vertical axis

Embodiment Construction

[0014] refer to figure 1 , indicated by 10 is a high-concentration solar generator using a solar receiver according to the invention. The generator 10 includes a support structure 12 fixed relative to a stationary base 14 . In the example illustrated in the figures, the support structure 12 comprises two triangular side supports, each formed by two legs 16 converging upwards. The bottom ends of the legs 16 are secured to the base 14 . The top ends of each pair of legs 16 are secured to a respective top support 18 . However, the illustrated shape of the support structure 12 is not mandatory and may vary depending on the application.

[0015] The support structure 12 carries reflectors 20 designed to concentrate solar radiation to a focal line A. As shown in FIG. In the example illustrated in the figures, the reflector 20 comprises one or more mirrors having a reflective surface 22 shaped like a parabolic cylinder. The focal axis of the reflective surface 22 coincides with ...

Abstract

The invention relates to a solar receiver for a solar concentrator with a linear focus. The solar receiver (26) for a linear-focusing solar concentrator, comprising: - a base (28), which is elongated in a direction parallel to a focal line (A) and carries an array of strip-shaped targets (34) arranged orthogonal to said focal line (A) and set at a distance apart from one another in a direction parallel to the focal line (A); - a focusing assembly (40) including an array of optical elements (44) arranged for focusing solar radiation on said strip-shaped targets (34), the focusing assembly (40) being mobile with respect to the base (28) of the photovoltaic receiver (26) in a direction parallel to said focal line (A); and - an azimuthal pointing device (58, 60), designed to move the focusing assembly (40) with respect to said base (28) as a function of the position of the sun.

Description

technical field [0001] The invention generally relates to generating energy by concentrating solar radiation onto a photovoltaic or solar receiver. [0002] In solar concentration systems, it is desirable to obtain a high concentration of solar energy to increase the efficiency and yield of the solar concentration system and to reduce the amount of photovoltaic material in the case of photovoltaic systems. Background technique [0003] In order to increase the efficiency of a solar concentration system, it is necessary to perform pointing of the concentrator both according to the zenithal direction and according to the azimuthal direction. Document No. WO2005 / 116534 describes a solar concentrator comprising one or more concave mirrors rotatably mounted on a support structure about a horizontal axis and driven by a first motor to vary their zenith angle, wherein the A concave mirror concentrates solar radiation in the direction of one or more receivers fixed relative to the ...
