GREENoneTEC Solarindustrie GmbH traces its origins to the early 1990s, when founder Robert Kanduth started the business in a garage. Over the following decades the company grew into what it describes as the world's largest producer of thermal flat-plate solar collectors, based in St. Veit an der Glan, Carinthia, Austria. By the 2020s the company had a production capacity of more than 1.6 million square metres of flat-plate collectors per year and exported more than 85% of its production to more than 100 countries. In 2021 Austria's largest solar thermal plant, the Solarpark Friesach, was opened. With 5,780 square metres, it was unique in Austria in both size and concept, and its solar collectors were produced by GREENoneTEC. In 2022 the company celebrated its 30th company anniversary, with numerous long-standing customers and suppliers attending. In 2023 GREENoneTEC started production of solar carports, described as innovative, specially designed and industrially manufactured, with a broad range of flexible additional modules. In 2024 the company developed a flexible PV*T solution, a hybrid technology combining photovoltaics and solar thermal energy in a single collector, described as space-saving, sustainable and economical, and representing maximum energy yield, flexible application possibilities and high reliability. Throughout its history GREENoneTEC has focused on developing and producing thermal solar collectors and mounting systems, including customer-specific OEM versions, and supplying heating manufacturers, solar system providers, industry, energy utilities, public institutions, planners, project developers, wholesalers and commercial businesses.
