4,500 square metres of silicon solar cells on 20,000 square metres of land (approximately three football fields) transform sunlight directly into electric current; they produce about 600,000 kWh of electricity annually which can be used to provide electricity to 200 households. The Mount Soleil power station is also one of the biggest research and demonstration facilities in the field of photovoltaic power.

A well-established educational trail links the two mountains, Mount Soleil and Mount Crosin, in an appealing and enjoyable manner. Embedded in the typical landscape of the Bernese Jura, the trail leads you from one information board to the next, compellingly explaining everything you might wish to know about power supplies, wind energy, photovoltaic energy, the Jura wildlife and landscape, agriculture, and tourism.

An interesting alternative for visitors is to be taken directly by horse-drawn coach to the two power stations. As a consequence of ongoing expansion projects, the park will soon have two new wind turbines, making a total of eight.


Guided tours of both power stations, duration 1 hour. Bookings must be made in advance:
