Definitions

  • the concentrator has an inward-facing reflective surface
  • the solar collector unit includes at least a predetermined one of a first coating, formed on the inward-facing reflective surface, having high solar energy reflection; and a second coating, formed on the conduits, having high solar absorptivity and low emissivity.
  • conduits 22 and 24 extend along respective axes 14' and 14", such that optical energy impinging on an inward-facing, reflective surface, referenced 26, is reflected to conduits 22 and 24, and absorbed by the fluid flowing therethrough.
  • a solar collector unit referenced generally 110, which is similar to unit 10 of Figs. 1A and 1B in many respects, and in which all of the portions and components having counterparts shown and described herein in conjunction with Figs. 1A and 1B, are indicated by similar reference numerals but with the addition of the prefix "1".
  • the fluid employed may be any suitable liquid, such as water or oil, or any suitable gas, such as steam, air or argon.
  • a solar collector array referenced generally 50, constructed in accordance with an alternative embodiment of the invention.
  • Array 50 is generally similar to array 30, except for the fact that the conduit arrangements are connected in parallel, and not in series as in array 30.
  • Array 50 is thus not specifically described herein, except with regard to differences between array 30 and array 50.
  • Portions of array 50 having counterpart portions in array 30, are indicated in Figs. 4A and 4B by the same reference numerals, and are not specifically described herein except as may be necessary to understand the present embodiment.
