  2. It is non-pressurized. And it also can not be solarized in the sun without water inside. Otherwise, the glass tube is easy to be broken.
  3. There are many sizes for option. In a fine day, it can produce hot water quantity between 70 and 130kg/m2 based on 50?.
  4. High Absorption: αs≥90%; Low Emission: εh ≤8%.Daily Average Heat Efficiency: ηd≥50%
