A Vermont company manufacturing innovation solar trackers is the ninth fastest-growing energy company in the country, according to Inc. Magazine.

AllEarth Renewables started as a small company in Vermont. Founder and CEO David Blittersdorf comes from a background in the wind industry and developed a hardy solar tracker that can stand up to the elements and follow the sun across the sky to increase the energy output of standard ground-mounted solar photovoltaic panels.

The product did well in Vermont and the company started to expand out of Vermont at the end of 2011.

The company has grown 2,217 percent in three years and boasted $20 million in revenue in 2011. Inc. ranked AllEarth no. 148 among the 500 fastest-growing companies in the country and ninth among energy companies.

“We feel we have a good product to offer,” said AllEarth spokesman Andrew Savage.

And that is at the heart of the growth. More people are buying it, in part, because it’s worth buying.

The other part is that they know about it.

“A big part of our profitability, growth and expansion comes from our partner installers,” Savage said. “Over the last three years we’ve established partnerships with installers who understand the value in ground-mounted solar.”

On the heals of celebrating it’s rapid growth, AllEarth Renewables announced another strategic partnership with installer Transformations, which operated throughout Massachusetts.

Announcements like that have become more and more common as the solar trackers make their way into states throughout the Northeast for the first time. Right now, growth is concentrated in the north Atlantic states, but there is plenty of room for the company to grow nationally.

“As our installer network establishes itself and expands, I think we’ll continue to see growth,” Savage said.

The Vermont company has also worked to develop a product and business model that works in a wide range of projects from small residential systems to expansive utility-scale installations.

“We also have a bankable financing model,” Savage said. “And we have a good track record now. I think we’re going to continue to see growth like this.”
