Dow Says Out With Solar Panels, In With Solar Shingles
Dow Says Out With Solar Panels, In With Solar Shingles

Forget those bulky rooftop solar panels–the hot new thing in solar energy could be rooftop shingles that convert sunlight into electricity, and that blend in seamlessly with the standard asphalt shingles that top most houses. Dow Chemical has announced that it will begin selling its Powerhouse Solar Shingles in limited quantities in 2010, with a full roll-out the following year.

Dow executive Jane Palmieri says the shingle incorporates a low-cost, thin-film photovoltaic cell device for capturing solar energy. Roofing contractors do not need specialized skills to install the product, she said. The cost was estimated by Palmieri at $27,000 for an array of solar shingles to offset 60 percent of a home’s power consumption . While that may seem pricey, it’s still far below the cost of an equivalent solar panel system.

Dow expects the shingles to catch on with roofing contractors because they can be installed in about 10 hours, compared with 22 to 30 hours for traditional solar panels, reducing the installation costs that make up more than 50 percent of total system prices. The product will be rolled out in North America through partnerships with home builders . The shingles are the first product to come to market from Dow’s developing line of “Building Integrated Photovoltaic” (BIPV) systems, in which power-generating systems are integrated into traditional housing elements. In 2007, Dow received $20 million in funding from the U.S. Department of Energy to work on BIPV technology.

1. actually, from the estimates I've done, $27k is about what it costs now
to put a large photovoltaic system in your house.

I'm not sure where they get the 'far below' information.

... range. It really doesn't tell me much about the costs of the product. Which makes me wonder if they don't really want to say yet.

I'd like to see some price projections per kilowatt installed. I realize it will start out higher and then come down as production efficiencies take effect.

Anyway, glad to see another major player in the market.

(Edits to correct my lousy typing this morning.)

4. My thoughts exactly
The numbers in this article are so vague it's impossible to really determine the viability of the product. Perhaps that is intentional...

6. I think we should differentiate between production costs, and market costs.
Prices currently more reflect the market price caused by supply and demand, not the production costs per panel. Once we have significantly more producers the supply in the market will be able to more easily meet demand, reducing the overall market costs significantly.

A 1000 watt solar panel, from a quick google search, ranges between $5900 to $8200, this in an environment where producers are claiming less than $1 per watt. Even if you were to say that outlaying expenses aren't included in the "less than $1 per watt" equation (which wouldn't be how I'd calculate the "per watt" number), 6 to 8 times the production costs is purely due to market mechanisms.

This results in naysayers claiming that the price of solar panels isn't dropping therefore they're untenable, yet the price isn't dropping as dramatically as production efficiencies occur because demand is skyrocketing.

8. The consumer should simply look at cost/kwh for this forever and ever and ever and
Edited on Wed Oct-07-09 02:53 PM by NNadir
ever (soon to be competitive with coal, gas, windmills, Jovian 30 moon tidal generation, nuclear, fusion, wound up rubber band form of energy.

The solar industry has a website where one can compare energy prices and skip the (illiterate) (peak) watt talk.

I reference it all the time. The latest energy price with the swell, wonderful, fabulous, great, solar industry can be found at the bottom of the 2nd column, in the table linked, residential prices for electrical energy, 35.61 cents/kwh as of this writing, the figure being for September of 2009.

http://www.solarbuzz.com/SolarPrices.htm

I don't see what's so mysterious about that. This is about a factor of 3 greater than grid powered electricity.

Since I've been writing here, about 250 billion tons of the dangerous fossil fuel waste carbon dioxide have been dumped in that great dump, earth's atmosphere. For the whole time, 7 years, people have been blabbering endlessly about solar would soon be competitive.

I continually have been pointing out that this stance is just what it's been for almost half a century, denial.

11. Power produced doubling every two years...
Consumer shouldn't care about price, consumer should wait until adoption is readily available at low costs. Production costs are not the same as market costs.

5. Knowing Dow, these are probably made from Dioxin-coated asbestos and crushed baby seals.

7. Nah, it's leftover silicone from when Marrion Merrill Dow exited the inflatable boob business.

9. Hurtful statement, but I'd have to agree.
They'll stamp them with a bunch of :) though, and it'll be all good.

10. The toxicological implications of the solar toy industry are about to become abundantly clear.
It will be big news before this hyped industry is able to produce even one exajoule of the 500 exajoules humanity uses each year.

12. Yeah, and Nnewcuelur is just so darn clean and cute.
We heard you the first nine thousand times.

I'm going to blog the hell out of my solar & wind setup just for you, Captain Exajoules.

I will bet you that you will fail to blog all about the energy consumed by your consumerist blog, Private Can't Count.

You have no fucking idea where your swell solar and wind set up came from, how it was made, or where it will go when it's become another piece of consumer detritus abandoned like old transistor radios after they were no longer flashy and cool.

It's not like you're intellectually capable of considering how many computers dedicated to reading your (as in "I, me, mine) blog can be powered by your (gasp) blogged "set up."

Maybe I'll blog my gas furnace. Da ya think people will be interested? No? Why not?

If your fucking consumer toys were common place, they wouldn't be interesting at all, would they consumer boy, certainly no more interesting than my gas furnace? Why is my gas furnace not interesting? Because almost everyone can have one. One of the things that stupid "solar is wonderful" people never seem to get is that if there stuff worked it wouldn't support much blogging interest.

By the way, kiddie, it's not like I've been missing the nine hundred thousand times little bourgeois shits have come here to announce that "solar will save us." We've all been hearing that over and over and over and over and over and over and over again, since the scientifically illiterate Amory Lovins told us all, back in 1976, that there would be 18 quads of solar energy in this country by the year 2000.

One thing about the whiny bastards in the anti-nuke cults is that they can give it out but they can't take it. Like all bourgeois brats, they want one set of rules for other people (like say, Bangladeshis who don't have anything and therefore are incapable of jumping on the "conservation will save us" bandwagon so hyped by people whose average power consumption is 12,000 watts, 24/7/365.25) and another set of rules for themselves.

But of course, our little shit for brains consumers have always had selective attention. They whine and whine and whine and whine and whine that people who point out that they are little consumerist shit for brains repeat themselves.

Go ahead. Blog away. Tell us all about your swell solar and wind "set up." We're all dying to hear endlessly and endlessly and endlessly about your consumer stuff so we can all be impressed by your nobility. Because, what's life about? Is about some poor fucking slob ingesting electronic waste in say, India. No! Of course not!!!!! It's all about some brain dead Westerner talking about his stuff.


Do let us know about how you plan to dispose of the inverter for eternity after it burns out http://www.springerlink.com/content/r7347txq7567357m/?p=612b4a040f814ee29de322f1d09ece99&pi=3">my fine oblivious friend. And speaking of obviousness, I'm sure you can't even grasp the QED you've provided with your threat of (gasp) blogging about your stuff.

One more thing: Measurement is a fundamental practice in science. The exajoule is a scientific unit. The fact that all the "solar will save us" fundies mock that unit is a reflection of their obvious contempt for science. QED again. Got it fundie boy?



Have a nice indifferent bourgeois consumer evening fundie Kiddie...
