A solar collector having a blow-molded frame and an integral absorber plate. The frame is larger in thickness than is the thickness of the absorber plate portion. The absorber plate portion of the blow-molded part has a channel system molded therein for conveying a liquid therethrough. The blow-molded part has rigidifying sections therein to enhance the stability of the solar collector.
