Detailed Product Description

Features: 
1) Integrate solar energy with building
2) Decorate the house appearance
3) Safe, healthy, energy saving and environmentally friendly
4) Material:
    a) Copper tube
    b) Aluminum alloy
    c) Other material as per customer's requirements
5) Types:
    a) Glass vacuum tube collectors:
        i) High efficiency
        ii) Can supply hot water at any time
        iii) Compare with flat plate collector, it hides some potential safety hazard,
              the possibility of bursting of a tube
    b) Heatpipe collector:
        i) High efficiency 
        ii) Operating safe and stable 
        iii) Water quality requirement
        iv) Higher cost
    c) U-tube collector: 
        i) Better heat conduction (a little lower than all glass vacuum tube collector)
        ii) No danger hidden
        iii) The system is not all optimized
        iv) Higher cost
    d) Flat plate collector:
        i) Long service life 
        ii) Fewer malfunctions
        iii) Less danger hidden 
        iv) Low cost 
        v) With frost free design, resolves the frozen problem, therefore can be
            used even in winter
        vi) No requirement of degree of vacuum
        vii) Higher efficient conduction
        viii) Stable quality
        ix) Water or working fluid goes through the mental collector tube without
             touch of glass capping plate, which avoids bursting of the tube caused
             by shock cooling and heating that can make the system paralyzed
        x) Can be installed gapless, thus has functions of the traditional roof (keeping
            warm, insulating, obscuring, water proofing) while providing hot water.
            Can replace part of or the whole traditional roof
        xi) The length, width or dimension can suit different building roof or wall
        xii) Can endure high pressure, operating safely and stably
