The project involved three stages:<\/strong>

An initial photovoltaic generation test was conducted near the dam, on the shores of the lake, from 2013.

Poralu Marine helped to develop a floating solar farm to serve as a demonstrator, which was commissioned in 2019.

The farm was extended to cover 35% of the lake\u2019s surface, with 67,000 m\u00b2 of solar panels on approximately 1,000 floats anchored to the lake\u2019s shores.

The project is a world first at high altitudes. Ultimately, it will generate almost 23 million kWh every year. <\/p>\t\t<\/div>\n\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t

Because the project is located at high altitude (1810m),the challenging climate of the Alpine environment had to be taken into account in the design of the floating structure. Temperatures can plummet to -30\u00b0C, winds can reach 120km\/h, the lake freezes (with ice up to 60 cm thick), and the area receives heavy snowfall (up to 50cm).

Currently, the farm covers 2,240 m\u00b2. It is built on a floating aluminum alloy structure capable of withstanding the extreme conditions. The floats are made using high-density polyethylene. Romande Energie S.A. attached the solar panels to the structures, then placed them on the water as a unit.

The aircraft-grade aluminum structure requires little in the way of moorings and is attached to the bottom of the lake with weights, allowing the floating structure to rise and fall with the water. <\/p>\t\t<\/div>\n\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
