The world’s first high-altitude floating solar power plant continues to generate power above the lake in the Swiss Alps. This plant produces 50 percent more energy than those whose panels are found in lowland areas.

The solar power plant in Lac des Toules consists of 1,400 panels placed on 36 floating structures made of aluminum and polyethylene plastic fixed to the bottom of the lake.

Production of 800,000 kWh per year

“This pilot project generates 800,000 kWh per year, corresponding to the [needs] of 220 households,” says Maxime Ramstein, Project Manager at Romande Energie.

The mountainous conditions at an altitude of 1,810 meters above sea level make the sun’s rays stronger. The solar power plant is installed in a reservoir and not in a natural lake, which limits its environmental impact.

The technology found in the floating power plant is also an important part of the photovoltaic industry worldwide.

Ramstein also says that the problem of icing caused by cold weather is solved by draining the reserves that are filled due to melting snow in the spring and summer months.
