Evacuated tube solar collectors are one of the most common and simplest forms of the solar technology field. The mechanism of working of an evacuated tube solar collector is like leaving a jar exposed to radiation and letting its liquid contents heat up, although the evacuated tube solar collector works in a more complex and also more efficient way than the stated mechanism.
The basis of all solar thermal systems is the transfer of heat – from the sun''s radiation to a solar fluid, from the fluid to a heat exchanger and from the exchanger to the domestic supply. There''s no need to understand the physics of actual heat transfer, but it is important to understand where heat goes and what happens when it does.
