The invention relates to a parabolic trough collector comprising a parabolic, trough-shaped main reflector, preferably as a steel girder construction running holding device with a plurality of support arms for holding of the main reflector, an absorber tube, which extends along the focal line of the Main reflector extends and in which a heat transfer medium is heated, and a foundation, wherein the holding device on the foundation by a vertical axis is rotatably mounted.

Disclosed is a rotation apparatus of a pole system for photovoltaic power generation, the rotation apparatus comprising: a first tubular body connected to a solar panel array; a second tubular body coupled to a lower portion of the first tubular body and fixed on the upper end of a pole; a gear unit for transferring rotating force to the first tubular body; a driving motor for providing the gear unit with the rotating force; and a contact part of at least 3-points of contact, which is installed on coupling portions of the first tubular body and the second tubular body and maintains a contact state during the relative rotation of the first and second tubular bodies to transfer the power or a signal.

Provided herein is a solar energy light collecting device, which includes a light reflection module, a sun tracking module, and a control module. The light reflection module includes reflection units, reflection unit support beams and a support wheel frame assembly. The sun tracking module includes an angle adjustment set, a height adjustment set, and a supporter set. The control module includes a sense control unit and a driving motor. The sense control unit senses the direction of the sunlight and controls the driving motor to drive the sun tracking module, such that the light reflection module faces the direction of the sunlight. Moreover, an additional balance adjustment module can also be adopted to resolve the spatial disposition problem.

A solar power system (11) which comprises a plurality of solar energy collecting means (10,10a,10b,10c) respectively comprising a platform assembly (16,16a,16b,16c) floating on liquid in a liquid reservoir (14,14a,14b,14c), each platform assembly carrying solar energy concentrators or collectors and respective reservoirs (14,14a,14b,14c), being interconnected in series and arranged in a cascading relationship such that the flooding of a platform assembly (16,16a,16b,16c) in one reservoir (14,14a,14b,14c), for protection of the concentrators or collectors under liquid displaces liquid in that reservoir (14,14a,14b,14c), and causes the flooding of an adjacent lower platform assembly (16,16a,16b,16c) to protect the concentrators or collectors carried thereon.
