Photovoltaic Roof Shingles

All of our homes have large roofs that soak up sunlight all day long, why not harness that energy to offset our energy costs. Photovoltaic shingles look to be a promising way to do exactly that.

“Homeowners have long been able to partially power their homes with sunlight, but it meant clumsily mounting photovoltaic (PV) panels on the roof. Now the latest generation of PV panels look and act much like ordinary roofing tiles or shingles. And the National Institute of Standards and Technology (NIST) is evaluating nine of these commercial PV roofing products in hopes of providing an easy way for consumers to judge the panels’ power potential.

A lot of people are considering the use of PV products on their homes and businesses, and in order to make decisions on whether it’s a worthwhile investment you need to predict their performance,” says Hunter Fanney, head of NIST’s Heat Transfer and Alternative Energy Systems Group in Gaithersburg, MD. “We are collecting detailed performance data to validate those models.”
