Cornelia Daniel is a solar entrepreneur, author and speaker.

In 2011, when photovoltaics was still a niche topic in Austria, the graduate in business administration founded the company Dachgold, which supports commercial enterprises in the implementation of their photovoltaic systems. 

The great mission of her life is loosely based on Bill Gates: "On every company roof a PV-plant". The first step towards this goal was the initiative "Tausendundein Dach" in 2014, a solar initiative for companies for which she was elected Austrian Woman of the Year in the field of climate by the newspaper "Die Presse" in 2020. The goal was to solarize 1001 roofs in seven years, primarily using economic arguments and prime costs instead of payback periods. The success proves her right.
