Westwood Professional Services has chosen Unirac to supply the mounting system for its recently-completed solar array on the Minneapolis Convention Center. Unirac’s ISYS Roof Mount’s ability to support an acute module angle tilt and withstand the city’s harsh weather conditions saw it selected for the 600kW array.
“We selected Unirac for this project based upon their willingness to work within the design specifications of the project and their ability to deliver a first-class product,” said Nathan Franzen, director of solar energy at Westwood.
In winter, the system is likely to be subjected to wind speeds reaching 120 mph and snowdrifts up to eight-feet high. In order to cope with these extreme conditions and maximize solar gain, Unirac was forced to tailor the roof mount and its IRM configuration accordingly: it has an irregular rooftop design that slopes in multiple directions; adjustable feet to ensure an array in plane or level with the roof; a 30-degree module tilt; and extreme flexibility of north-south and supporting beams.
“[The] ISYS Roof Mount’s unparalleled flexibility proved to be ideal for this site and project, and Unirac’s deep expertise in resolving design complexities was also integral to this project’s success,” said Unirac’s president and CEO, Doug May. “Our team provided a seamless installation that adhered to a strict timeline. We are confident that Westwood will continue to be a key partner for Unirac in the renewable energy sector, and we value working with a company equally dedicated to quality and service.”
With 2,613 modules, the centre’s system is one of the largest in the American Midwest and it will generate around 750MWh of electricity per annum.
