How Facet™ Mount made a 4.88 MW, non-ballasted solar array possible on a fully adhered TPO roof—delivering utility-scale performance, long-term durability and proven reliability under extreme environmental conditions.
The warehouse roof was a non-ballasted, fully adhered TPO system with an 8-inch clearance requirement – eliminating ballast as an option and sharply limiting attachment choices – yet still needed to support a system large enough to offset more than 60% of building demand.
The design also had to handle Northeast extremes: freeze/thaw cycling, hurricane-level winds and heavy snow loads, all while keeping point loads as low as possible to protect the roof and maintain watertight integrity.
White Rose Foods deployed a 4.88 MW rooftop solar array at its grocery distribution warehouse in Carteret, New Jersey.
The system consists of more than 22,000 solar panels generating approximately 6.2 million kWh annually, replacing roughly 6 million kWh of grid power each year with clean, renewable energy.
Installed on a fully adhered TPO roof, the project required careful consideration of structural loading, wind uplift, and long-term roof durability due to its unprecedented scale.

Facet™ Mount enabled a non-ballasted, nearly 5 MW rooftop solar system on the fully adhered TPO roof, where ballast and traditional attachment methods were not viable.
Engineered to withstand freeze/thaw cycles, hurricane-level winds and heavy snow loads, the system incorporated waterproof washers and heat-welded flashing made from the same roofing membrane to ensure long-term watertight performance. Installation efficiency further supported the project’s scale, with each mount installed in under six minutes.
The result was a landmark East Coast installation that validated Facet Mount’s durability and established a repeatable behind-the-meter model for utility-scale solar on complex commercial rooftops.

“When it comes to solar energy systems, especially solar photovoltaic systems, bigger is better, and the biggest one to date is the 5 MW rooftop system proposed for the White Rose Building in Carteret, New Jersey. The building is both the corporate headquarters and a food distribution hub for White Rose Foods, the largest independent wholesale food distributor in the New York City metropolitan area.”
