U-Anchor 2000 Holds up to "Super Storm" Sandy on 1 Megawatt Rooftop Solar Project in Yonkers

YONKERS, NY – The U-Anchor 2000 solar racking attachments for low-slope roofs held firmly during Hurricane Sandy on a nearly completed 1 Megawatt photovoltaic installation in Yonkers, according to the project’s roofing contractor.

“That was one good part of that project, the anchors held,” according to Tim Kraft of Kraft Roofing Company in Fairlawn, New Jersey. Kraft and his crew had installed 90 percent of the U-Anchor 2000 solar rooftop attachments for the project and most of the solar racking before the storm struck.

According to Joel Stanley, President of Anchor Products, “Contractors have reported installation times of eight times faster than the competition, without the need for penetrating the roof membrane or adding ballast.”

The roof membrane receiving the U-Anchor 2000 attachments was a fully adhered, reinforced 60 mil EPDM membrane. The 16 inch targets of the U-Anchor 2000 attachments were adhered to the roof membrane with seam splice tape. The Schletter Solo5 solar racking system was attached to the rooftop with the U-Anchor 2000 solar attachment system from Anchor Products. The Schletter Gator Clamp held the racking system to the posts of the U-Anchor 2000 attachments.

The U-Anchor 2000 attachment system has passed rigorous testing to the ASCE 7-05 and the ASTM E330-02 (2010) standards. The independent testing lab at Trinity ERD found the U-Anchor 2000 to have approximately 1,000 lbs of ultimate load capacity. The test results demonstrated the product can perform in wind events exceeding 180 mph due to the U-Anchor 2000’s high tensile strength and shear strength.

Weather warnings for Yonkers reported hurricane force winds and extreme wind gust were recorded in the vicinity of the 1 megawatt solar project. The multi-story building on which the photovoltaic panels were installed are in the vicinity of the George Washington Bridge where Highway 7 crosses the Hudson River. Winds speeds recorded on the George Washington Bridge exceeded 90 mph during the worst of the storm.

The roof project did sustain damage due to flying debris and building materials which punctured the EPDM roof membrane, creating more than 32 holes that will need to be repaired. But neither the U-Anchor 2000 nor the Schletter solar racking system were damaged by Super Storm Sandy, according to Kraft.

Anchor Products, LLC, of Grapevine, Texas, developed the U-Anchor 2000 rooftop attachment product for ballast-free, non-penetrating roof membrane attachment of solar module racking systems. The U-Anchor 2000 is a lightweight equipment attachment system consisting of a weatherized steel plate with a 3/8” by ¾” tall stainless steel stud, which has been heat fused to a 16 inch by 16 inch (40 cm by 40 cm) thermoplastic (PVC or TPO) target. The U-Anchor 2000 attachment is designed to be installed without fasteners and is a highly wind-resistant enhancement for solar panel racking installations.

The U-Anchor 2000 can also attach lightning protection equipment, electrical conduit, plumbing pipes, HVAC ducting, satellite dishes, windscreens, antennas, and mechanical system components, among many others. For more details, please contact us.
