About Fronius
The Fronius story begins all the way back in the 1940s. At that time Günter Fronius founded a simple one-man business in Pettenbach.
The founding of Fronius’ youngest business unit, Fronius Solar Energy by second generation owners, Brigitte Strauß and Klaus Fronius dates back to 1992 with a focus of “technology of the future”.
