Dow Ready to Debut Solar Roofing

Dow Chemical is rolling out a new kind of solar roof that could make adding solar power generation a simple and inexpensive process.

The company is integrating film solar cells into roofing shingles that are nailed onto the roof just like conventional asphalt shingles.

The concept still isn’t perfected, but builders Pulte Homes and Lennar Corp. have successfully tested prototypes.

Dow’s Chief Technology Officer William Banholzer estimates that 250 shingles covering 1,000 square feet of roof and generating 3.5 kilowatts on a sunny day will cost the average homeowner $10,000, half of which he would have incurred anyway to put regular asphalt shingles on his roof.
