Dow Solar Shingles Now Available in Northern California and Central Texas



 
Dow recently announced that it was expanding market availability of its solar shingles, the solar shingles are now available in Northern California and Central Texas (San Antonio and Austin, Texas).

In Northern California, the clean energy shingles are available through Town & Country Roofing and Dority Roofing; in Central Texas, they are available through BELDON Roofing CompanyQuality Roofing and Ja-Mar Roofing.

We’ve covered these solar shingles many times, but for anyone new to this technology, the shingles protect one’s roof the same as normal shingles would, but they also act as power generators via their incorporated solar photovoltaic cells. Dow’s “Powerhouse Solar Shingle” comes with a 20-year warranty and “has received seven performance and safety certifications, including the backing of Underwriters Laboratories (UL)International Code Council Evaluation Service (ICC-ES) certification, California Energy Commission Certification and is proven to withstand rain, hail and wind uplift.”

An included monitoring system delivers real-time production and consumption information that can be viewed online.

As we’ve noted before, solar power generally improves the resale value of a home, and I assume that holds true when a home is equipped with solar shingles rather than traditional solar panels. “Houses with solar sell on average twice as fast as comparable houses without solar, and adds to the total home value,” said Kasey Dority, President, Dority Roofing.

It’s unclear what these solar shingles cost, and as always, I’d recommend looking into all the options available to go when going solar. But if you’re deciding between roofing your house with standard shingles or solar shingles (not interested in going solar in some other way for some reason), my bet is that solar shingles pay off better in the long run. But let us know if you have any info from looking into the matter.

    “With respect to whether solar shingles are cost-effective for residential solar, one of the most influential factors is solar efficiency. Reportedly, solar shingles are only 10% efficient (meaning that 10% of the solar energy that strikes the surface can be converted to solar electricity), while solar panels are 13% efficient. In addition, the cost of solar roofing is about 10-15% more than ordinary PV panels.

    Some experts are predicting a cost of about $50 per square foot, with an output of 600 watts for every 100 square feet.

    Homeowners can take heart in the fact that solar shingles, like ordinary solar panels can qualify for tax incentives and rebates that can defray the cost an additional 30-50%. One estimate is that a solar shingle system for an average homeowner in Michigan will cost about $11,200, including rebates.

    Consider these benefit of solar shingles:
    •Installed just as regular asphalt roofing shingles
    •Waterproof, glass-free and encased in UV-stabilized polymers, solar shingles are practically virtually indestructible.
    •They can be dropped from a roof, walked on and stacked in pallets like any other type of roofing shingle
    •Connections are simpler than for ordinary solar panels because solar shingles plug into each other to form a solar array.”

      My understanding is that these aren’t really intended as a competitor for PV panels, they are intended for people who won’t install PV panels for aesthetic reasons or for people who are only permitted to install shingle systems due to heritage or homeowner association regulations. It doesn’t matter a lot how they compare with standard panels if the people considering them wouldn’t or couldn’t install panels anyway, the only question is are the economics of shingles adequate to justify their installation, based on their lower efficiency and higher cost one would expect there economic case will simply lag behind PV panels by a year or two.
