SolarCity’s New Mounting System Adds 20-50% More Panels Per Roof

SolarCity’s acquisition of residential solar module mounting startup Zep Solar is paving the way for commercial customers to add 20 to 50% more solar panels on a roof, while reducing installation time from two to three days to less than one, Greentech Media reports. “The east-west orientation allows more panels on each roof than standard south-facing systems and also captures peak power production over a longer period of the day,” Wesoff writes. “SolarCity claims it also allows more efficient sizing and operation of the solar inverter.” The new system “makes it possible for far more businesses, schools, and other organizations to install solar power on their buildings and immediately pay less for solar electricity than they pay for utility power, and will significantly expand the addressable market for commercial solar,” notes Jeff Siegel, Editor of Energy and Capital, writing on AltEnergyStocks.
