Demand is growing for renewable
energy sources, and there's no source
more abundant than the sun. It is with
that in mind that CertainTeed has
developed a photovoltaic (PV) system
that is truly the first of its kind. The
EnerGen Photovoltaic Solar Roofing
System features integrated UNI-
SOLAR thin-film laminates that
seamlessly integrate with traditional
asphalt roofing shingles.
