摘要:
Examples and variations of apparatus and methods for concentrating solar radiations with trough solar energy collectors are disclosed. A support assembly for a trough solar energy collector has a plurality of transverse ribs attached to longitudinal rails and end assemblies secured to the rails. End assemblies may attach to longitudinal rails through transverse ribs, and guy wires may span from one of the end sections to the other. Transverse ribs may be formed of two rib sections with semi-parabolic shape. Solar energy collecting panels may be placed on the ribs and secured with cowlings and transverse panel-retaining strips, for instance.

Foam backed solid support structure and trough solar energy collector. A support structure has foam or other polymeric material, a plurality of end arms, and a plurality of end caps secured to the formed foam material. The foam material is cut into a parabolic or semi-parabolic shape, and a reflective element may be placed onto the formed foam material and secured mechanically, with adhesion, and/or integrated with the surface. A solar energy collector formed using a polymeric core may have longitudinally-extending cowling, end caps, and end arms as described.

Disclosed are systems and methods for controlling arrays of solar thermal energy collectors. Rows of the array are actuated sequentially or consecutively rather than concurrently.
摘要:
Solar energy reflector, collector, array, and other equipment for converting solar energy to e.g. thermal energy. A reflector or collector may, for instance, comprise a plurality of longitudinal rails; a rib engaging and spanning the plurality of longitudinal rails; and a first mirror panel. The rib of the reflector or collector may have a slot that is parabolic or in the shape of a section of a parabola. A portion of the mirror panel such as an end portion or a portion located away from the ends may be positioned within the rib's slot.
