An extruded solar panel formed as a unit and including a plurality of co-planar fluid passageways joined side by side and having at least one radiation transmissive cover extending over the passageways. The edges of the cover are joined to the edges of the group of passageways to form a dead-air space over the passageways. The opposite longitudinal edges of the cover and passageway structure have flanges that can be interlocked for ease of assembly, and one or more ribs are provided to support the passageways from the roof structure.
