A solar energy conversion unit having a collector forming a focal area in which is disposed a core assembly including a governor arranged for varying the surface area of fluid carrying tubes partly forming the core assembly that is exposed to solar radiation so as to maintain a desired fluid pressure within the conversion unit. At such time as the solar radiation impinging the collector becomes substantially less than that necessary to maintain suitable pressure in the fluid system of the unit, an auxiliary heater provided as part of the core assembly can be employed to supplement or replace the solar radiation.

A solar energy conversion unit, comprising, in combination: (a) a collector forming a focal area for radiation received from the sun; (b) frame means for mounting the collector for movement with the sun; (c) core means forming a fluid passage and mounted on the frame and arranged at the focal area of the collector for receiving solar radiation from the collector and heating a fluid passing through the passage formed by the core means, wherein the collector is a longitudinally extending trough substantially semicircular in cross section, with the core means including a plurality of tubes arranged extending longitudinally of the extent of the trough and forming a further trough having a semicircular cross section, the tubes and collector being arranged substantially concentrically with one another with the tubes being disposed within the trough, wherein the collector has a pair of substantially parallel, spaced, longitudinally extending, peripheral edges, and includes a cover comprising a pair of cooperating doors arranged pivotally mounted on the edges of the collector by longitudinally extending hinges for swinging movement toward and away from one another.
