A pole mounted dual axis solar tracking apparatus has a main mounting member [13] in a fixed primary north-south axis which is inclined to accommodate geographical latitude and a cross arm [16] fixed to the main mounting member and defining a secondary east-west axis. A support frame [15] for PV panels, solar reflectors etc. is pivoted to the cross arm to enable the support frame to tilt over the secondary east-west axis. The apparatus is highly efficient due to its ability to sweep through the shape of two conjoined cones. The apparatus operates with close to the efficiency of a dual axis tracker but with the simplicity of a single axis tracker.

The present application describes an automated structure for reception of modular constructions and respective automation system comprised by a lower structure (1), which contains an opening (4) for accommodation of a fixed shaft, comprised by the element of attachment of the shaft with the exterior, where, preferably, the structure and the fixed shaft of fixation to the exterior (5) can be coupled, a lifting mechanism (2) preferably located in the side sections of said lower structure (1) which is coupled to an upper structure (3) allowing its movement through the joint and support (6). The axial movement and the upper structure (3) are managed through an automated system based on a programmable automaton and a set of sensors and actuators, namely anemometers and frequency inverters that control these movements. This way, the present invention makes it possible to receive modular constructions, for example houses, making them move, for example, according to the solar orientation, in order to make them energy efficient.

A solar panel assembly having a foundation tube, a rotary actuator mounted in the foundation tube for changing the azimuth of the panel and a linear actuator mounted to the foundation tube for controlling the elevation angle of the panel. The linear actuator utilizes a spindle drive. The rotary actuator includes a motor and gearbox; a drive screw connected to the motor; a spindle screw, one end of which provides an output of the rotary actuator; a drive nut having a first threaded hole for receiving a thread of the drive screw and a second threaded hole for receiving a thread of the spindle screw, the guide nut having a guide fin; and a guide rail interacting with the nut guide fin to constrain the nut from rotating, whereby the rotation of the drive by screw by operation of the motor causes the nut to translate linearly which in turn causes the spindle screw to rotate.

The invention relates to a device for concentrating solar radiation (1) including a concentration means (2), capable of concentrating solar radiation onto a concentration area, and a solar radiation receiver (3), characterized in that the receiver (3) is connected to at least one so-called thermo-deformable element (4) capable of changing shape by means of temperature, each thermo-deformable element (4), when the radiation from the concentration means (2) is concentrated onto a concentration area located on said thermo-deformable element (4), being capable of changing shape so as to cause movement of the concentration area in the direction of the receiver (3), or movement of the receiver (3) in the direction of the concentration area, so that the device (1), for a given solar position and by means of the solar radiation, enables movement of the concentration area from an initial position located on a thermo-deformable element (4) to a final balance position located on the receiver (3).

A shape-memory actuator device for maintaining an orientable member, in particular a solar generator (2), in a position aligned with the sun, comprises a distribution of lenses (12) for focusing the direct or indirect solar radiation (R) on a shape-memory element (13) as the position of the sun varies. The device further comprises a shielding member (14), which is connected in rotation to the orientable member (2) and is controlled by the shape-memory element (13) when the latter is activated following upon the heat generated by the solar radiation as far as a position in which it shields the lens (12) which is focusing the direct radiation (12). In said condition, the shape-memory element is de-activated, and the shielding member returns into a position in which it again uncovers the focusing lens (12). The shielding member thus continues to perform oscillations about the position aligned with the sun, following at the same time said position as the sun moves.

摘要:
The invention concerns an adjustable reflector (1) which comprises a plurality of reflector elements (2) which each have a reflector surface (3) and are pivotably disposed. The reflector elements (2) can pivot in at least two directions and/or are mutually coupled and pivotable together. The reflector surface (3) can comprise a tensioned aluminium or silver foil. The reflector elements (2) can be at least partially transparent spheres. According to a further configuration, the reflector surface is disposed in an equatorial plane of the spheres. It can be produced in a particularly advantageous manner from the point of view of manufacturing techniques if the spheres are each assembled from two hemispheres, the reflector surface being formed on the flat surface of one of the two hemispheres. Preferably, in order to be parallel and jointly pivotable, the reflector elements can be coupled in a particularly structurally simple and elegant manner if, according to a further advantageous embodiment of the invention, the spherical reflector elements are clamped between two plane parallel plates of which at least one is made of a transparent material. If one of these two plates is displaceable relative to the other plate whilst the spacing therebetween is maintained, a corresponding displacement rotates the spherical reflector elements, clamped between the two plates, in the same direction, such that the surface normal of their reflector surface is adjusted or pivoted in the desired manner.
