Abstract
A solar radiation absorbing structure including a plate comprising a plurality of co-planar fluid passageways joined side by side and having at least one radiation transmissive cover extending over the passageways. The opposite longitudinal edges of the plate parallel to the passageways and the corresponding longitudinal edges of the cover are interlocked with longitudinal rails to support the passageway plate and cover spaced from the roof structure. Only one part of each rail and plate and cover is locked in place on the roof; the remainder is free to move in response to thermal expansion and contraction. Manifolds at each end of the plate connect to the passageways to transmit liquid to and from the passageways. At each end of the cover a member, which may be hinged, forms, with the manifolds, a substantially airtight enclosure in cold weather.
