WILLISTON — Inc. magazine has named AllEarth Renewables to its annual Inc 500|5,000, a ranking of the nation’s fastest-growing private companies.

AllEarth Renewables ranked 148 and was the ninth-fastest-growing energy company nationwide. The Vermont solar company had a three-year growth of 2,217 percent with revenues of $20 million last year.

“We responded to the rapidly growing solar market nationally by designing and manufacturing a product that makes strong financial sense for both residential and commercial customers, as well as our growing team of solar installers,” said David Blittersdorf, CEO of AllEarth Renewables.

The company manufactures the AllSun Tracker, a pole-mounted solar system that uses innovative GPS and wireless technology to follow the sun throughout the day to boost solar energy production by up to 45 percent over roof-top installations.
