How licensing works
Every state sets its own rules for who may install solar. Some license solar contractors, some license electricians or home improvement contractors, and some leave it to cities and counties. Before you switch on, the work is permitted and inspected, usually by your city or county, and your utility gives permission to operate.
Our own crews install every system. Renewable Energy is a trade name of Renewable Energy 1989, LLC.
