SunTrap Solar Selective Coating

SunTrap Solar Selective Coating

The SunTrap uses a unique cutting edge solar selective coating. The SunTrap coating has a dual functionality:

    It enhances absorption of incident flux by having low reflectivity and high absorptance in the solar bandwidth.
    It reduces energy losses by having low emittance of thermal radiation.

What distinguishes the SunTrap Solar Selective coating is that it is stable in air which enables the novel design of the SunTrap receivers that eliminates vacuum around the absorber tube.

The SunTrap Solar Selective performed has been confirmed to be stable up to 650C, by Fraunhofer Institute for material science in Germany.
