Tube Length : 1800MM / 2100MM
Material : Glass tube – 1.6 Borosilicate glass 3.3
Absorptance : >92% (AM 1.5)
Emission : <8% (80℃)
Vacumm : P<5 X 10° PA
Stagnation Temperature : >200℃
Heat Loss : <0.8 W/59M
Maximum Strength : 0.8 MPA
The Evacuated Tube Collector (ETC) Solar Water System is more efficient than Flat Plate Collector (FPC) system because of the shape of Glass Tubes (Round Shape).
Evacuated Tube Collector System has a benefit over Flat Plate Collector that Sun’s Rays fall perpendicular on the ETC Tubes throughout the day, which is not in case of PFC. Hence it directly helps to get high temperature water as compared to PFC System
Also, because of the Vacuum in between the glass of the tubes, heat loss at night is low, when the temperature is pretty low. This helps the System to maintain its temperature overnigh
