MATERIALS USED FOR MANUFACTURING SOLAR DOMESTIC HOT WATER

An absorber may be made from a wide range of materials. Copper tubes is the most common material used for the fluid passageways, while mild steel or stainless steel and mild steel tubes are also in use. Tubes are bonded to an absorbing plate (a good thermal bond is required for tube and plate) from copper or aluminium or steel (mild or stainless).
