Solar Roof Shingles

Solar manufacturer Sunflare debuted a series of solar residential shingles at the Solar Power International Show this year. Designed to cover the entire roof, the thin-film shingles install with standard methods and snap-together electrical connectors. The manufacturer says that the lightweight, waterproof shingles are encapsulated in durable, lightweight polymer solar sheets and have a temperature coefficient of -.31% per 1°C (for each degree the shingle warms, its output decreases .31%). Each cell has a by-pass diode, so only shaded cells become inactive if in shadow, according to the maker. Pricing will be available soon. sunflaresolar.com
