Sunerg - Model HV12 -Evacuated-Tube Collectors

Evacuated tube collector with U-pipe technology. It is composed by 12 glass tubes, which have inside a U shaped copper tube on an aluminum fin in order to convert solar energy in thermal energy. The absorber surface area is bigger than the gross surface area because of a CPC reflector (Compound Parabolic Concentrator), which optimizes the direct and diffuse radiation from morning to evening. This kind of construction allows to achieve a higher rates of efficiency, compared to other evacuated tube collectors without CPC reflector, and prevents heat loss, even at sub-zero temperatures.
