Comparison between Evacuated Tube Collector & Flat Plate Collector
For a solar thermal collector to be effective it must minimize conduction (by using good insulation) and convection (by using a sealing barrier). A solar thermal collector therefore can only gain energy through radiation, hence the development of selective coatings that absorb radiation but limit the amount re-radiated.
