Exploring Dow Solar Shingles

I've been interested in seeing if we could put solar shingles on the house to make it more energy efficient.  There are two options, and I've been talking with the local (San Antonio) DOW Powerhouse dealer.  The other vendor was relatively non-responsive. 

I sent him the elevation plans and the site plan, and after correcting them -- they had the house turned the wrong way on the site -- we got the proposal you can see here.  What I don't yet have is the pricing.  Our architect was guessing between $20- 25K, but that was with the original which had half as many units.  The builder is guessing closer to $30K. 

Unfortuntly, unlike Austin, the local power companies offer no rebates for installation of solar panels.  That leaves only the Federal Tax Credit -- which isn't that great.  I don't believe we're going to see a good return on the investment, unfortunately.

Here it is.
