A solar collector of modular configuration includes a plurality of evacuated collector elements disposed on opposite faces of a manifold in a staggered array. The manifold includes a central baffle which divides it into two parallel passageways through which the heat transfer medium, typically art, may be supplied to and removed from the collector elements. Each of the collector elements comprises an elongate double wall glass tube with one open end, the annulus between the walls being evacuated to a high vacuum. A thin wall metal distributor tube having a diameter marginally smaller than the inside diameter of the collector element and a length marginally longer seats within the collector element. The annulus defined by the distributor tube and inner collector element wall communicates with the proximate passageway and the distributor tube communicates with the distant passageway. |
