Abstract: A thin support structure for solar collectors is provided. The support structure includes service lines, such as fluid lines and electrical signal lines, disposed within an interior cavity of the support structure. The movement and flexing of the service lines is accounted for by a pulley assembly having a rotating element, without the need for complex and expensive swivel joints and slip rings.

Abstract: To overcome shortcomings of the conventional thermal receiver, embodiments of the technology disclosed herein are directed towards an improved thermal receiver. More particularly, the various embodiments of the technology disclosed herein relate to thermal receivers without a vacuum insulation, otherwise known as an approximation of a blackbody. Various embodiments of the technology disclosed herein enable greater absorption of sunlight collected by a parabolic solar trough concentrator compared with conventional thermal receivers.

Abstract: The invention includes a parabolic solar concentrator typified by a highly integrated structure whereby, mirror, aerodynamic elements, a shell structure, cooling elements and other elements have been integrated to form a unibody structure, which is both stiffer and lighter than traditional trough structures. The invention includes; aerodynamic features that greatly limit lift forces induced by high speed winds, a receiver with liquid cooling for better control of PV cell temperatures and which allows for the collection of the heat for beneficial use, accommodations for a solar tracker, and improvements in the focusing and distribution of light using secondary mirrors. The receiver incorporates specific details to improve heat transfer and reduce parasitic pumping loads and incorporates secondary mirrors to increase light acceptance angles. Automated mirror washing is addressed.
