Turnkey rooftop PV systems

Based on many years of cooperation in the rooftop PV sector ENERGISTO together with the responsibles of TISIBA Group set the starting point for a joint venture in Switzerland. A country which has a pioneering role in energy production from renewables (56% hydro power) has only achieved a share of 1,5% solar power by 2015. Given the solar potential in Switzerland 20% a coverage of the own electricity demand is possible by 2050.
With the approach to combine German and Swiss engineering an own swiss company has been established. The primary goal is to offer PV components made in Germany and Europe as well as to use synergy effects in purchasing, planning and project development within this group of companies.

Local scope of work

  • Planning and realisation of turnkey rooftop PV systems in Switzerland with an international focus.
  • Individual PV solutions for various types of roofs.
  • 360° approach to enhance self consumption of own produced solar power.

Performance season 01 (summer 2015-2016)

  • More than 35 projects with over 3 MWp capacity installed. The achieved high quote of residential installations is a vital column of our corporate development.
  • Realised self-consumption optimisation incl. first implemented storage systems with residential and public buildings.
  • Lighthouse project: 1.6 MWp rooftop PV installation within 4 weeks construction time. Contracted by a large German solar PV enterprise.
