1. A solar heat absorber panel having a pair of superimposed sheets marginally sealed together, said sheets being secured together inwardly of said sealed margin thereof by longitudinally interrupted weld connections to provide a plurality of laterally spaced longitudinally extending internal flow passages extending substantially from end to end of said panel, laterally extending header spaces adjacent the ends of said panel in direct communication with said internal flow passages, inlet and outlet fluid flow fittings at opposite ends of said panel, each fitting having a chamber projecting above said panel across one of said header spaces centrally between opposite sides of said panel at the outer side of said chamber and tapered at the inner side thereof to form a restricted portion extending into one of said flow passages to laterally distribute fluid flow to the internal passages at both sides of said fittings, the header space at each end of said panel sloping from the central portion thereof laterally outwardly in a direction toward the opposite end of said panel so that said passages decrease uniformly in length from the central portion to the sides of said panel, thereby to improve drainage and to provide for a more even distribution of fluid flow through said passages.
