Renewable energy is energy that comes from natural resources, such as the sun, wind, water and geothermal heat. Many view renewable-energy systems as the solution to offsetting rising energy costs and becoming "green."
The most common renewable-energy systems a roofing contractor encounters are rooftop solar energy systems, particularly photovoltaic (PV) systems and solar water heating (SWH) systems, also known as solar thermal heating systems.
Roofing companies throughout the U.S. are contemplating whether they should incorporate rooftop solar energy system installations into their business offerings. Interested contractors must be familiar with information specific to solar energy systems, as well as unique issues that may affect their installations, such as licensing, code compliance and NRCA guidelines.
