The present disclosure relates to a parabolic trough concentrator to harness the sun's energy. The parabolic trough concentrator 5 comprises a trough concentrator structure 6, two semi-rigid reflecting sheets 50, a receiver 60, a support stand 80 and a telescopic mechanism 90. The parabolic trough concentrator 5 is designed to have a large reflecting surface area when it is in its extended state, and have a very compact footprint when it is disassembled, folded and collapsed to its retracted state.

Disclosed is a reflective solar apparatus comprising a light receiving device and at least one light reflecting device. The light receiving device delimits a first light receiving surface used for receiving sunlight. The light reflecting device is provided on a side face of the first light receiving surface and has a curtain-type reflecting surface and a driving mechanism used for driving the curtain-type reflecting surface to expand and retract. When the curtain-type reflecting face is completely or partially expanded, sunlight reaching the curtain-type reflecting surface is at least partially guided to an area where the first light receiving surface is located. Since a curtain-type reflecting surface able to expanded or retract is used, not only can the sun be tracked but also the curtain-type reflecting surface can be expanded or retracted according to the strength of wind power.
