Hoping to form a combination as successful as the iconic chocolate peanut butter cup, CertainTeed is mixing its residential roofing products with Energy Conversion Devices' thin-film flexible solar laminates. The companies believe placing lightweight UNI-SOLAR cells directly onto asphalt shingles will make clean, renewable solar energy a more attractive and viable option for homeowners. The joint line of photovoltaic residential roofing products will hit the market in 2010. CertainTeed Corp., 800.223.8990;
