The invention relates to a holding device (1) for a solar panel (2) on a parapet (3) of a balcony, said device having at least the following components: —a connection arrangement (4) for connecting an element to be held, wherein the connection arrangement has at least one support (5, 6, 7, 8) for placing on a parapet; and —at least one transverse strut (9, 10) for bridging a parapet width, wherein the at least one transverse strut is connected to the connection arrangement and has at least one flange (12, 13) for placing on a parapet, wherein by means of a movement of the at least one flange towards the connection arrangement, the at least one flange and the at least one support press in opposite directions against the parapet. The invention disclosed relates to a holding device which allows for greater flexibility with regard to the structure of a balcony parapet.

The element on which solar radiation is concentrated, specifically, a vacuum tube, remain static at all times with respect to the movements that a parabolic reflective surface may make according to the direction of solar radiation, such that inlet and outlet pipes of the vacuum tube do not need to be articulated, which facilitates the installation and insulation thereof and reduces production costs. The parabolic reflective surface can pivot 360° with respect to the vacuum tube without interfering with the pipes, allowing an active safety system for protecting against strong winds and preventing overheating to be produced, in addition to allowing the surfaces to be cleaned by means of nozzles spray pressurized water. The collector also includes passive safety means against strong winds.

The invention relates to a tracking device (1) for solar modules (2a) with a series of posts (3) arranged along a longitudinal axis. A crossmember (6) is pivotably mounted on each post (3), and said crossmembers (6) are pivotable about a common pivot axis (S) extending parallel to the longitudinal axis. There is fastened to each crossmember (6) a toothed ring (7) of which the toothing (7a) is in engagement with a motor-driven toothed wheel (8) mounted on the respective post (3). Also provided is a positive guide means which forms a safeguard against a transverse displacement of the toothed wheel (8) relative to the toothed ring (7). Each toothed wheel (8) is mounted on the side of the respective post (3).

A multi-scissor jack-operated single-shaft solar tracking apparatus. A scissor jack is provided at regular intervals on a rotation beam of the single-shaft tracking solar support, thereby forming a multi-drive rotation. Lifting screw of each scissor jack is connected by a drive shaft so as to be lifted in synchronization. One of the scissor jacks can be driven by a motor, and the lifting screws of the other scissor jacks are driven by the transmission shaft, thereby synchronously driving the rotation beam of the single-shaft tracking solar support to rotate. The scissor jacks can be driven by manpower, in order that the angle of the tracking solar support can be adjusted by hand.

An assembly for positioning photovoltaic panels on a structure includes a main frame connectable to the structure, and a subassembly connectable to the main frame to support a photovoltaic panel, in which the subassembly is rotatable with respect to the main frame to place the subassembly in a deployed position. The assembly may further include a stop-arm connectable to the main frame to support the subassembly when in the deployed position.
