Working Principle
SunSurfs solar thermal collectors use fluid circulation (usually water or an antifreeze solution) to transfer the heat for direct use or storage in an insulated tank . Water/glycol has a high thermal capacity and is perfer in cold climates. The direct radiation is captured via the evacuated tubes absorbs the radiation as heat and conducts it to heat pipe then the transfer fluid in the manifold made of copper. Metal makes a good thermal conductor, especially copper and aluminium. The fluid carries away the absorbed heat, thus cooling the manifold (see fig 2 above). The warmed fluid leaving the collector is either directly stored, or else passes through a heat exchanger to warm another tank of water, or is used to heat a building directly. The temperature differential across an efficient solar collector is usually only 10 or 20°C. While a large differential may seem impressive, it is in fact an indication of a less efficient design.
