Solar radiation map of Europe
Austria had 173.8 MW of photovoltaics at the end of 2011, 78 MW of which was installed that year. Most of it is grid connected.
In 2009, the site of Zwentendorf power station became Austria's largest solar power station with an investment of 1.2 million Euro, with the addition of 1000 photovoltaic panels. Zwentendorf was intended to be Austria's first nuclear power plant, but after a vote in 1978 prohibiting nuclear power in Austria, was never completed.
In September, 2011, Austria's largest solar power station, 2 MW, was under construction in the Niedere Tauern mountain range.
