Renewable power company Heinzel Energy, part of Austrian pulp and paper giant Heinzel Group, has acquired a 51% stake in 3F Solar Technologies.

The Vienna-based company has developed a unique solar hybrid collector known as Solar One, which convinced Heinzel Energy to invest in the start-up.

“This product has already attracted interest on a global scale, and perfectly extends our wind power and hydropower portfolio to encompass solar technology as well,” said Heinzel Energy Managing Director Christoph Heinzel.

Solar One employs both PV modules and solar thermal energy panels to generate both electricity and heat to warm water.

3F Solar Technologies says the new system not only generates double the added value on available space but also reduces installation costs by 50%. “In addition to single family homes and larger housing projects, Solar One is particularly suitable for businesses and hotels – for every building which requires electricity and heat on site,” says 3F Solar Technologies Managing Director Alexander Friedrich.

The company adds that the collectors can be directly integrated in the roof and seamlessly installed right up to the roof edge instead of the roofing tiles.

Heinzel Energy, also known as Heinzel EMACS Energie GmbH, has until now specialized in hydro and wind power for its parent company’s energy intensive pulp and paper operations. It operates hydropower plants in the Austrian state of Styria and in Upper Austria, which supply power to Heinzel Group’s pulp and paper companies Zellstoff Pöls AG and Laakirchen Papier AG. It also operates a wind farm in Burgenland at the 1,000-hectare Domaine Albrechtsfeld organic farm — also part of the Heinzel Group, which is likewise active in agriculture and real estate.
