Advantages:

S-type tube flat plate solar collector, with gotten the line patent in China
We are famous factory to produce S-type tube flat plate solar collector, no any welding on the tube, no any leakage
Laser welding between whole absorber panel and copper tube, high strength thicken, heavy duty aluminum frame
Much better than some technology of ultrasonic welding or heat-conducting glue in some factories
The instant heat efficiency of the collector can up to 81.1%, much higher than the 72% standard, very rare in China
Germany imported high efficient selective blue titanium coating
Used best copper tubes in domestic, copper brand is Hailiang
Special low-iron tempered glass with transmittance more than 92%
Mechanical load, freeze resistance, rain penetration, exposure, hail impact, external and internal shock tested etc.
Long lifetime, large absorber area, good warm keeping
