Photovoltaics have taken on greater significance in the area of building systems engineering, particularly since the government approved the private use of energy produced off-grid. Indeed, the Swiss power grid will see major changes in the near future in connection with the decentralised storage of solar power. We know the latest developments on the market and can competently advise you in all matters relating to solar power generation and use.

  • Feasibility studies, pilot projects and comparison with alternative plans
  • Investment strategies for real estate portfolios
  • Private use optimisation
  • Building integration
  • Developer support and representation
  • Facilitation of feed-in remuneration and one-time remuneration options
  • Solar power strategies for PSCs
  • Proof of origin marketing
  • Founding of solar power cooperatives
  • Roof use contracts
  • Solar installation consulting programmes for energy cities and regions
  • Surge arresters and EMC


Architectural design
