Abstract
Abstract A flat plate solar collector system embodying a plurality of individual conventional solar collector panels in which the frames of said panels are provided with notched portions or recesses for the reception of union type pipe couplings joining the headers of adjacent panels to permit the several panels to be assembled in butted side-by-side or precisely contiguous relation. Additionally, cover plates are provided for the recesses to present a unitary appearance to the assembly.
