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.

A dynamic controllable system for moderating energy absorption at the earth's surface includes a series of panel units mounted above the earth's surface over land and water masses or on buildings. Each panel unit supports rotatable shafts, with panels joined to or integrally formed with the shafts. Each panel (forcing) has a radiation reflective surface and a radiation emissive surface opposite the radiation reflective surface. The panels are selectively rotated into a predetermined one cardinal positions: reflective, emissive and neutral, or into an intermediate position between cardinal positions. The programmable controller receives various data including top of atmosphere satellite data, air temperature and relative humidity at panel units, weather data, time of day, position of panel units, radiation insolation, and combinations thereof. Responsive to real-time data, both local and regional, the programmable controller directs rotational orientation of panels, causing a desired reflection of shortwave and longwave radiation away from the earth's surface.

Solar trackers that may be advantageously employed on sloped and/or variable terrain to rotate solar panels to track motion of the sun across the sky include bearing assemblies and other mechanical features configured to address mechanical challenges posed by the sloped and/or variable terrain that might otherwise prevent or complicate use of solar trackers on such terrain.

The structure of a concentrator mirror includes a prefabricated body of reinforced concrete, which includes a panel member having a front surface with a reflective laminar layer, and a back surface, between which a hinge axis for the rotation of the panel is defined. A pair of coaxial hollow seats are formed in the body at respective longitudinally spaced positions, to define the hinge axis together with respective spherical joints. The body includes a rib shaped counterweight appendage extending parallel to the hinge axis from the back surface of the panel member, on the side opposite the front surface, so as to bring the hinge axis in a barycentric position of the body.

A sun-tracking solar drive can include hardware and/or be operated in accordance with a method in which angular deviations are compensated for operation including during forward tracking and backtracking. For example, the effects of thermal expansion and mechanical slop associated with certain components can be calculated and used for calculation of target angles that can provide for increased power output and improved shading avoidance.
