Sonnenkraft GmbH is a manufacturer and system provider of solar solutions. It is only logical that the company decided to equip the new canopy at the St. Veit an der Glan location with a photovoltaic system. At 1650 m², the largest flying roof in Austria was equipped with 800 double-glass photovoltaic modules with bifacial cell technology. This means that the modules can absorb sunlight from both sides. The roof now delivers an annual yield of 325,000 kWh per year, which corresponds to the electricity needs of 85 households.

First, Sonnenkraft wanted to invest in a construction with tarpaulins. Since this had neither a long service life nor an attractive design, they switched to a wooden construction. For this purpose, the HASSLACHER group supplied 11 fishbelly beams from the Hermagor location. Each beam is made of 6.9 m³ of glued laminated timber (local spruce), whereby one fishbelly beam corresponds to the volume of wood used for the roof truss of a single-family house. Together with the general contractor Vivatro GmbH, also from St. Veit an der Glan, and local metal workers, carpenters, electricians and planners, the flying roof was built in just 8 weeks.
