Our innovative Rooftop Solar Program – the nation’s largest advanced solar photovoltaic project – is generating cleaner renewable power in an environmentally sustainable fashion. By positioning solar stations on the roofs of existing warehouses in sunny, inland areas, we are putting otherwise-unused rooftops to good use. The program is designed to generate as much as 220 megawatts DC of solar power with rooftop and ground-mounted photovoltaic panels, both by us and by independent power producers.
