The detail of material:

Outer tank: Al-Zn coated steel sheet/color steel

Inner tank: SUS 304-2B stainless steel sheet

Insulation: polyurethane foam

Vacuum tube: borosilicate glass 3.3

Inner pipeline: stainless steel tube with aluminum fin

Absorption coating: Al/copper/stainless steel

Stand: aluminum alloy/galvanized sheet

Max work pressure: 0.3MPa

Evacuated tubes convert solar energy into thermal energy that is transferred to stainless steel tunes by an aluminum fin with high solar energy absorption and low heat radiance loss. Solar collector can still work even with several tubes broken.
