Evacuated tube solar collectors (also called vacuum tube solar collectors) are higher efficiency solar collector, simpler installation and lower cost than traditional flat plate solar collector. It is widely used in solar central hot water engineering system , and they are the central part of Solar Water Heater, they convert sun energy into thermal heat via the vacuum tubes.
The design of the vacuum tube solar collector is very flexible. It can be used to make the appropriate support and installation method according to the installation size of different building roofs. We can design and produce mounted stand according to actual ground size of installation location for you.
SolarShine’s Evacuated tube solar collector are Φ58 * 1800 high efficiency collector vacuum tubes with all- glass double- tube co- axial structure.
