GREENoneTEC is a pioneer: In the late 1980's Robert Kanduth started building absorbers and solar collectors in his garage. The 40 square meters have become 28,000 and grown into a "solar park". GREENoneTEC, founded in 1994, exports its technology to more than 40 countries worldwide (exports make up 85% of sales) and has a market share of 25% in Europe.
In 2013, GREENoneTEC turned over 90 million euros. The company has eight collector production lines which currently comprise more than 100 customer-defined collector variants.
