Abstract: Low cost solar collector panel utilizes surface mounted tubing in which the inner wall portion of the tubing is copper to permit the use of untreated water in the system. The outer wall portion of the tubing is aluminum which provides additional strength and is easily attached to a low cost aluminum absorber plate. A method of producing the composite aluminum-copper tubing in long length coils is disclosed. The tubing can also be formed into connectors for connecting copper and aluminum tubing together.
