Restrictions on rooftop loads for commercial buildings can be a roadblock to installing photovoltaic panels. SolarCity—which sells, installs, finances, and monitors solar energy systems for building operators and homeowners—found a way to mount solar racks in commercial applications that disperses their weight effectively. LightMount, the company’s nonpenetrating curb, adheres to the roof membrane and reduces the panels’ distributed weight from approximately 4 pounds per square foot to 2 pounds per square foot, helping roofs accommodate heavier systems. The mount is available for commercial projects that use the company’s solar photovoltaic system. solarcity.com
