Agility and efficiency for Madrisa Solar

Madrisa Solar in Klosters is located at an altitude of approximately 2,000 meters above sea level and will be part of the regional energy supply. It began feeding electricity into the grid in September 2025. This represents pleasing progress since the groundbreaking ceremony in June 2025. The construction company Vetsch Klosters is using three Mounty® BL90 drill feeds for the construction of the Madrisa Solar project.

Why Mounty®?

In alpine terrain, every minute counts: maneuverability, short transport routes, and precise drilling are crucial. The portable Mounty® BL90 perfectly meets these requirements with its flexible maneuverability – ideal for the 3,170 solar panels of the project.

Project details Madrisa :

  • Annual production: approx. 17 GWh, of which over 40% is winter electricity (October–March)
  • Investment volume: approximately CHF 70 million.
  • Construction period: June 2025 to the end of 2027

NalpSolar – a pioneering project in Tujetsch (GR)

Lumesa is also actively involved in the Nalps solar power plant project in the community of Tujetsch (Graubünden), together with the companies STRABAG and Geowork. Located at approximately 2,000 meters above sea level, the plant will have an installed capacity of 8 megawatts and an annual production of approximately 11 gigawatt-hours. This corresponds to the electricity consumption of 2,000 households. The project sets standards for alpine photovoltaics: efficient winter production and adaptation to challenging terrain. A total of approximately 1,500 solar panels will be installed.
