Copper Soalr Energy Glass Evacuated Tubes use vacuum tube solar collector to eliminate the heat loss of the gas convection and conduction, and the application of selective absorbing coating makes the radiation heat loss down to the minimum. It structures pressure well and can work in high temperature.
