As more people continue to realize the advantages of clean, renewable energy sources, municipalities and local governments around the country have begun rolling out new regulations for installing solar systems.

San Francisco is leading the pack. The city’s Board of Supervisors recently passed legislation requiring solar panels be installed in all new residential and commercial buildings 10 stories or shorter.

Since solar systems are a long-term investment, building owners should ensure they’re installing durable, high-efficiency panels to optimize their ROI.
