Dow Unveils Impressive New Powerhouse Solar Shingle System (with Photos)

POWERHOUSE1

Yesterday, Dow Chemical Company (NYSE: DOW) unveiled its new line of DOW POWERHOUSE Solar Shingle. The Solar Shingle was designed to be integrated into rooftops with standard asphalt shingle materials. Dow expects the shingle systems to be available in limited quantities by mid-2010 and more widely available in 2011. And although the company says the system will provide a low-cost solar option for homeowners, we have not received any specific pricing details at this time (see below).

The POWERHOUSE Solar Shingle is made with CIGS photovoltaic cells in a proprietary shingle design.  Roofing contractors won’t need any particular knowledge of solar array installations, and installations should be quick because conventional roofing shingles and Solar Shingles can be applied at the same time.

Jane Palmieri, Managing Director of Dow Solar Solutions, described the benefits of the integrated system as follows: “Consumers reap the benefits of our innovation. This is about providing roof protection and electricity generation all from one product, with lower costs, improved aesthetics, easier installation and long-lasting performance.”

In conjunction with the announcement, Reuters reported that the CIGS cells used by Dow “operate at higher than 10 percent efficiency, below the efficiencies for the top polysilicon cells — but would cost 10 to 15 percent less on a per watt basis.”  This, in turn, should make the Solar Shingle about 30-40% cheaper than other BIPV systems.

      at least someone out there is trying to make a difference…

       I like them. Being that they are 10% less efficient (but cheaper) I
      think they would be probably best used in conjunction with solar panels
      that are on the optimum face for solar on the home or maybe along with a
      wind turbine. But its a good idea overall.

    Why is “for-profit” become such a negative connotation in this country? Accusations of GREED have become passé…but of course YOU aren’t the greedy one…its always the OTHER guy that’s greedy…

    Why do YOU have ad space on your blog?!?!

    these look far better than having a large solar panel on your roof

    Very cool! Hopefully they price them so that they are in reach of the average home. Someone is trying to make solar energy simple without the need for special training and special people. This is what we need to launch solar into the mainstream and get everyone to do it. Every new house that does not have a green roof should have these on it.

    Sweet! Way to get around those HOA rules and Regulations holding back so Many of my customers!! Everyone likes Price Reduction and Simplicity!

    Not quiet as nice looking as these: http://www.netzeroenergy.org
    But the more in the market the better, and DOW Chemical has huge potential to grow this business.
    I would have liked to have seen some more technical details, for example rated power per tile/shingle, and interconnect method.

    The solar part is apparently from Global Solar – please see http://greeninc.blogs.nytimes.com/2009/10/07/dow-unveils-solar-shingles/

    Step by step, before the “Big Bust” we are gaining independence and survivability, now get all the Solar you can, Super- insulate against heat loss, cooling loss, and grow a garden, not a lawn, the next normal, healthy down cycle in our capitalist economy may well hide the greater depression in its troughs, and with a dollar falling like a stone, Gold over $1000.00 and ounce and oil at $80.00 bbl, and the strongest “Yuan” in world history competing directly against the extremely weak dollar, expect oil to soar, causing hardship in U.S.A., Be very careful, our farming industries depend on cheap oil, so food prices might rise with oil! We will need Solar power to get us through the hard times. Consider LED lighting, with re-chargeable battery systems for totally off-grid and free lighting! Beware! Coal can be commendered for refinement to “Ersatz” fuel for Military / Civil defense purposes, and will not be cheaper with high oil prices! America goes through challenging energy times, shortages will abound! Safety in off-grid concepts good for emergency lighting at least! Remember too! The sun always shines – a perpetual source of heat, light, electricity. The wind, the same perpetuity, but good at night too! Both need batteries to store energy for practical, on-demand use, but do work well when properly installed! Solar, a good place to venture forth in energy independence! Next you’ll be forming communes to buy Wind Turbines, turning good solid profits!

    Ugly, no, beautiful, yes. I want them as soon as I can get them. For those interested in the technical details. take a look at patent #7,587,864. I believe this may be the one that Dow is using. If anyone can get their hands on product specifics like price and availability, please post back.

    I don’t think they’re that ugly…not pretty, but not ugly!

    These solar shingles sound interesting, but pricing will determine how successful they are.

    Solar roof tiles are becoming more and more important to the green energy movement. They are easier to install and utilize, and look a hell of a lot better.

    This is important because as of now the want of installing a solar power system is definitely in the minds of most Americans. However the price and the effort of setting up a system is a little daunting to some. As the price tag lowers and the rate of efficiency improves dramatically solar energy is looking much more alluring for the average house owner.

    Dow’s really been stepping it up, we’ll see how they do with their solar shingle.

    Always liked the integrated solar shingles for residential applications. This is especially helpful for people living in HOAs who do not like the aesthetics of typical solar panels.
