A new dealer partnership will allow AllEarth Renewables to expand the distribution of its dual-axis AllSun Trackers to the Midwest and beyond.

Day & Night Solar, based in Illinois, commissioned a project in the winter and has now signed on as an official AllSun dealer. The partnership will enable AllEarth Renewables to move into new markets. Day & Night will initially concentrate its AllSun Tracker sales in Pennsylvania, Ohio and Missouri, according to a release from AllEarth. But the full-service solar installer also has representatives in Arizona, Florida, Hawaii, North Carolina and Tennessee.

The AllSun Tracker was only available in Vermont a little more than two years ago. While still thriving in its home state, the company has concentrated on expanding its dealer network down the East Coast and progressively west. It started with Massachusetts. And the announcements about new territory kept coming throughout 2012. The latest announcement about Day & Night suggests that the Vermont manufacturer expects 2013 to be filled with even more partnership announcements.

“We have the capacity to meet whatever demand there is,” said AllEarth spokesman Andrew Savage. “We’re busy, but we’re still committed to free next-day shipping for our dealers.”

Brad Pitt’s high-profile Make It Right Foundation even selected the AllSun Tracker for a skate park project in a Hurricane Katrina-ravaged New Orleans community center in the fall.

“We have found that our partners like that the tracker differentiates their business,” Savage said. “Rooftop solar all kind of looks the same. Our partners like to offer something different and it gives them something to offer when rooftop won’t work.”

The AllSun Tracker uses GPS technology to follow the sun throughout the day and can boost solar energy production by as much as 45 percent overage an average roof-mounted system. A 6-kilowatt array is usually large enough to power a home.

Bob Eaton, managing partner of Day & Night Solar said in a statement that the return on investment is enticing to customers.
