Fueling solar power in the unlikeliest of places, Harmon Solar recently installed photovoltaic systems on the existing shade canopies of five Valley Shell service stations. Owned by Arizona-based The Carioca Company, these stations are only the beginning of a plan to install solar on 15 more stations in the coming year. Each Shell station requires approximately 220 panels to generate approximately $10,000 per year, per location in energy.
