According to TechnologyReview, “the latest generation of PV panels look and act much like ordinary roofing tiles or shingles”. This technology is currently being tested, no word yet on commercial availability.
Around 500 square feet of PV tiles can produce three kilowatts of electricity, according to Subhendu Guha, president and chief operating officer of United Solar Ovonic. “A south-facing roof on a three-bedroom home could supply 20 to 30 percent of the home’s electrical needs,” says Paul Maycock, a consultant and head of PV Energy Systems in Williamsburg, VA.
