#210 Solarenergie in den Schweizer Bergen mit der Solartanne

Switzerland needs electricity for the winter, and the mountains could provide it thanks to plenty of sunshine. Josef Grüter has developed the ideal solar installation for this: the Solar Fir Tree. Weather-resistant, snow-repellent, and easy to install. The Solar Butterfly has visited its first test installation — in Scuol in the Engadine.
