In this invention, a dual-axis solar tracker is presented to increase the energy produced by solar panels. The control strategy of this tracker is based on a hybrid of both astronomical algorithms and optical sensors and is designed in such a way that both actuators are not active at the same time. Also, the mechanical structure of the tracker is such that it is possible to rotate the solar panel 360 degrees around both axes. This makes it possible to track the sun in the early or late hours of the day or in some geographical areas where the direction of the sun ray is significantly inclined. Furthermore, the invented tracker consists of modular and ready-made mechanical and electronic components, and all the connections are in the form of bolts and nuts, which makes it fast and easy to assemble, install, disassemble and transport while having sufficient strength.

The application relates to a quantitative output apparatus and a group-control tracking support. The quantitative output apparatus includes: an actuator comprising an output wheel, an auxiliary wheel, and a passage portion; a transmission rope guided between the output wheel and the auxiliary wheel and passing through the passage portion; and a driving device for driving the transmission rope to move in the passage portion of the actuator. The transmission rope comprises a thick rope portion and a thin rope portion. When the thin rope portion passes through the to passage portion, the thin rope portion does not drive the output wheel to rotate. When the thick rope portion passes through the passage portion, the thick rope portion frictionally drives the output wheel to rotate.

Provided is a condensing device, comprising: a mounting platform structure, an energy-collecting structure, mounting frame structures, rotation devices, reflective mirrors, a drive device, guide rails and a telescopic device, wherein the mounting platform structure is capable of tracking east and west angles of the sun and rotates synchronously; and the reflective mirror can rotate in all directions on the mounting frame structure by means of the rotation device; the drive device is provided on the guide rail and may move along the guide rail, the curving radian of each guide rail is different, thereby enabling the rotation direction of each reflective mirror to be different; and the light reflected by the reflective mirror may be reflected onto the energy-collecting structure.

The present invention relates to a two axis tracking system (100). The present invention includes a frame (102), a solar panel PV module (112), an upper beam (114), a selectively flexible bracket (116), a first supporting pillar (118), a second supporting pillar (140), a lower beam (120), first strut (126), a second strut (146). The first supporting pillar (118) and the second supporting pillar (140) together act as the fixed link. The frame (102) acts as the rotating link and the lower beam (120) acts as the translating link. The first strut (126) and the second strut (146) together act as the fourth link connecting the frame (102) and the lower beam (120). The translation of the lower beam (120) causes rotation of the frame (102) in north-south direction. The PV module (112) is mounted on the frame (102) are rotated in east-west direction by translation motion of the upper beam (114).

A solar collector system comprising at least one heliostat and an inflatable cover configured to protectively conceal the at least one heliostat while it tracks the sun. The inflatable cover comprises a flexible membrane, which is transparent and colorless so that sunlight is transmitted through the cover. The cover may comprise an elastomeric material such as ethylene tetrafluoroethylene (ETFE). The solar collector system may further include a pump for inflating the inflatable cover, a pressure relief valve configured to prevent air pressure in the inflatable cover from exceeding a predetermined threshold, and a pressure sensor configured to automatically turn on the pump when the internal pressure falls below a predetermined threshold. The inflatable cover effectively removes wind loading from the heliostats, thus enabling the heliostats to use low-power, less-expensive actuators.

The disclosure relates to a solar tracker assembly, particularly for solar collectors, with a table structure for supporting the solar collectors, particularly solar collector panels and/or solar collector assemblies, and with an assembly for carrying the table structure, wherein the table structure is rotatable relative to the assembly base at least about one axis of rotation. For allowing the table for supporting respective solar panels to have sufficiently large dimensions in order to accommodate an increased number of solar collectors in an easy way and, at the same time, to enable the table to be positioned at a precise angle with reduced effort, it is suggested that at least a portion of the table structure and/or a portion of the assembly base is formed as a truss structure.
