2-MW project completed atop Mill 19 in Pittsburgh is now country’s largest single-sloped solar array

The last of 4,784 solar PV panels that will power Mill 19 at Pittsburgh’s Hazelwood Green site have been placed, marking the completion of the largest single sloped solar array in the United States. The $5 million project, completed by Scalo Solar Solutions, comprises a massive scale, covering 133,000 sq. ft across the frame of Mill 19. The project is made possible by the Richard King Mellon Foundation and the other foundations that comprise Almono LP, the owners of the Hazelwood Green site.


The panels were installed using an innovative access platform netting material, aptly called the Spider WorkWeb, and attached to the Mill’s existing steel structure in a manner taut enough for the solar installers to walk on. The slope of the roof is 20°, and the LG solar panels will will generate over 2 MW of power.
The over quarter-mile long Mill 19 structure includes the steel skeleton of the original mill building, formerly built by the Jones & Laughlin Steel Company in 1943. The tenants of this site include Carnegie Mellon University’s Advanced Robotics for Manufacturing (ARM) and Manufacturing Futures Initiative, and Catalyst Connection in Building A. Building B houses Aptiv, which recently entered into a joint venture with Hyundai to create autonomous or ‘self-driving’ vehicles.
A former brownfield site, Hazelwood Green is envisioned as a model of sustainable development. Mill 19 has been designed with the goal of achieving LEED v4 Gold certification, with a high-performance envelope providing maximum thermal efficiency and up to 96% daylight autonomy. 100% of the complex’s total electricity usage will be offset by energy generated on site, and storm water will be conveyed through a rainwater garden to centrally located infiltration basins. Captured rooftop rainwater will be reused in the cooling tower and for flushing in the restrooms.
