Cantsink Manufacturing Coming to Midwest Solar Expo in May to Showcase Solution for Special Problem Minnesota Community Solar Projects Face

Expo at the Downtown Minneapolis Hilton will attract solar developers in needs of foundations for community solar projects that won't shift during freezing and thawing

Cantsink Manufacturing will be showcasing its unique helical foundations for solar racking at the Midwest Solar Expo at the Downtown Minneapolis Hilton, May 17-19.

Cantsink's helical foundations will be displayed at the Expo for the first time in Minnesota, which is in the midst of a popular program to create community solar farms throughout the state. These foundations are designed to help solar projects avoid shifting that disrupts solar panel alignment. Using these helical piles creates low-maintenance systems that are easy to install and environmentally sound through the life of the project.

Long, cold winters are especially challenging for ground-mounted solar, such as the dozens of community solar projects now under way throughout Minnesota. The expansion of freezing moisture in the soil can push driven foundations upward, like water freezing in an ice tray. But solar panel racking dislodged in this process doesn't return to its original position when the ground thaws.
Repeated freezing and thawing over the 25-year lifespan of a solar project disrupts solar performance and requires expensive repairs.

Easy-to-install helical piles by Cantsink, a nationwide supplier to the U.S. solar industry, are engineered to anchor securely below the frost line, which can be as deep as 100 inches in some parts of Minnesota. Cantsink foundations create perpetual stability and avert the need for repairs and adjustments caused by Northern winter weather. Helical pile installation can be accomplished with readily available project site equipment and is engineered for accurate placement that ensures the right depth and alignment every time.

Best of all, Cantsink's helical piles can be recycled at the end of the project's life, adding to the long-term environmental sustainability of the investment.

Pat Hutchinson, president of Cantsink Manufacturing, said he is gratified that Cantsink's helical foundations provide an easy, cost-effective solution to a special problem solar projects face in Minnesota. He noted that the ideal suitability of Cantsink helical piles for overcoming the special challenge solar faces in this region is prompting a surge of interest from solar developers and installers.

"Cantsink is proud to offer Minnesota's solar industry a product that will assure them of long-term, high-quality performance from their projects," Hutchinson said. "We hope this can help prolong the popularity and momentum community solar is experiencing in Minnesota."
