3M Develops Low Cost Solar Mirror Film for Solar Thermal Troughs

3M Solar Mirror Film is highly reflective and can save "hundreds of millions of dollars" in construction of solar thermal plants

3M solar mirror film

3M has developed a very cheap solar mirror film that can be mass produced for the mirrors used in solar thermal trough technology. The process uses a polymer sheath with a sticky back, to provide a micro-layer of silver and copper that is highly reflective, so it can increase the power output and potentially save "“hundreds of millions of dollars” in the cost of constructing solar thermal plants.


The reflective foil that compromises the solar mirror film will cost about $20 per square yard and will pose stiff competition for Alcoa's aluminum based solar thermal technology foil.  Considering it cost Nevada Solar One $250 million to build their new solar thermal facility, 3M's solar mirror film technology could prove invaluable in making solar power more economically viable.

Since 3M has years of experience developing solar reflective film for windows in homes, office buildings and automobiles, it was a natural step for them to apply their expertise in developing this solar mirror film for the solar industry.

    Solar concentrators need to be cleaned quit often. I wonder if they have addressed the durability issues of.

    What is the spectral reflectance over the solar spectrum, 350 to 3500 nm?
    How long does it last in the sun?
    What about rain and other weather exposure?
    Have you seen edge peeling after a while?

    Thanks,

    I'm trying to make my ceiling look like a mirror instead of just placing mirrors. I'm thinking mirror film. Is your product something I could use to do this. The ceiling really is just a square frame box above my bed approximately 8 by 8 ft maybe! And if your film is what I'm searching for, is it available in Oklahoma.I live in Yukon, Oklahoma!maybe there is a store or 3M here!? Let me know please and thank you!
