PermaCity Solar has completed a 5.1 MW rooftop solar power system for fashion retailer Forever 21's headquarters in Los Angeles.
The array features 15,512 SunPower modules mounted on PermaCity's SolarStrap racking system. PermaCity developed the project under the Los Angeles Department of Water and Power's feed-in tariff and solar incentive programs. West Hills Construction built the array.
PermaCity says its SolarStrap system essentially bakes the panels onto the roof without any penetrations or ballast.
