The solar power plant planned by sol-E Suisse AG will be constructed in several stages. The first stage involves fitting solar cells on the 82m2 façade of the Sphinx Observatory. Due to the extreme altitude, the energy yield is expected to be around 70 percent higher than with the same type of solar power plant in the Swiss Mittelland plateau. This is the finding obtained from measurements performed on a test installation set up a year ago on the Jungfraujoch. The operating data provided by the new solar power plant are being scientifically evaluated for the purposes of further development in the field of photovoltaics, and for application in Bertrand Piccard's round-the-world flight in a solar powered plane (Solarimpuls). Founded in October 2007, BKW's subsidiary sol-E Suisse AG specialises in the installation of power plants throughout Switzerland for the generation of new renewable energies, primarily solar, wind, biomass and small hydro power. From BKW it has taken over not only the company's experts in such technologies, but also power plants that are already have a nation-wide reputation in this field, such as the solar power plant on the STADE DE SUISSE in Berne and the wind farm on Mont Crosin in the Bernese Jura.
