CertainTeed’s lightweight, durable photovoltaic panels mount seamlessly on a new or existing roof—no racks required—with the Apollo Solar Roofing System. The resulting look is sleek and clean, and the solar cells produce 12 watts of electricity per square foot. The 12-pound modules resist wind uplift and don’t require structural reinforcement of the roof. The system, which comes ready to install in pre-engineered kits, is Class A fire rated and qualifies homeowners for the 30% federal tax credit, the company says. 800.233.8990. www.certainteed.com
