Photovoltaic Roofing Shingles Installed

Project: Habitat for Humanity, Episode 5, Part 2



Deane Evans (from the Partnership to Advance Technology in Homes) and Ren Anderson (from the National Renewable Energy Lab) talk with Bob about special photovoltaic shingles, which convert solar energy into electricity. Bob and Ren begin applying the shingles to the shed roof, before Bob heads to Global Solar in Tucson, AZ to learn more about how photo voltaic film is manufactured.
Part 1: Installing Dimensional Asphalt Shingles
Part 2: Photovoltaic Roofing Shingles Installed
Bob talks with Deane Evans of the Partnership for Advancing Technology in Housing (PATH) about the photovoltaic roof shingles. This new product from United Solar Systems, called the Solar Shingle, generates electricity at the same time that it does the job of a normal shingle, protecting the house from the weather.

Ren Anderson from the National Renewable Energy Laboratory (NREL) shows Bob how to nail the solar shingles on the roof, just like conventional three-tab roofing. Here, eight solar shingles are blended into the conventional fiberglass shingles to provide about 120 watts for charging battery-operated tools and children's toys in the shed below.

Ren hooks up the wires leading from the shingles to the other system components, which include a fuse, a voltage regulator, and an inverter (which converts the direct current from the shingles into an alternating current that can be used by typical household appliances).
Part 3: Manufacturing Photovoltaic Devices at the Global Solar Factory
Bob Vila introduces the latest in sustainable materials and efficient building techniques on a Habitat for Humanity build. This project documents a five-day process that transformed an empty lot into a snug, comfortable, and sustainable home in Yonkers, NY.
