Largest Commercial Solar Rooftop System in Arizona Unveiled
Empire Power Systems this week completed the installation of an $11.5 million, 2.4 megawatt SunPower solar rooftop system on the Cowley Industrial Park building in South Phoenix. The project is the largest commercial solar rooftop system in Arizona and the second largest in U.S.
Cowley Companies, a Phoenix-based real estate investment firm, decided to install the solar system on this 850,000-square-foot warehouse because it houses food-service tenants that require large refrigerator and freezer units, which translate into high electricity bills. This was the company’s second solar undertaking; last year, Cowley added a 40kW, 188-module fixed mount system to the parking structure at its headquarters on Jackson Street in downtown Phoenix.
