Service focus

What the full installation secures on site

In Canton Genf, owners usually want a clear project flow from first assessment to handover rather than a loose mix of subcontractors. This page is built for that intent. From initial assessment and 3D survey through a transparent quote to full commissioning — one project, one process, one contact.

Service focus

  • Initial assessment and 3D drone survey: roof, orientation, shading, electrical setup and possible constraints — before any quote is prepared.
  • Transparent quote with clearly separated line items: material, installation, scaffolding, electrical, registration, commissioning — each one individually listed.
  • Coordination of Pronovo registration, metering concept, grid-operator queries and meter replacement through to full commissioning.
  • Optional integration of battery storage, wallbox and energy management — only where the usage profile and expansion goals support it.

Why this canton shifts the priorities

In Canton Genf, defensible quotes, clean project steering and commissioning without loose ends matter most. In the Canton of Geneva, SIG's «Solar Boost» offering complements the Pronovo one-time payment and the full tax deduction. Cantonal programmes (OCEN) additionally support roof renovations and battery storage depending on the budget. A direct check is worthwhile – rates are updated periodically. Geneva is one of the few cantons with a single, dominant utility: SIG (Services Industriels de Genève) covers electricity, gas, water, district heating, and fibre – and drives the solar offensive actively, including its own PV fleet on public rooftops and attractive ZEV/contracting offerings. Economics benefit from household electricity prices in the upper CH tier.

Regional framework

  • In Canton Genf, a pre-check saves time when permits, metering or electrical setup are not standard.
  • Owners want traceable quotes instead of aggressive package promises.
  • A documented commissioning reduces later questions and service overhead.

Tax and subsidy logic

In the Canton of Geneva, PV investments are 100% deductible as property maintenance – for both first-time installations and replacements. Costs can be spread over several tax periods if needed, smoothing the net burden. Geneva is shaped by Services Industriels de Genève (SIG) with their solar programme and Boost approach. SIG offers feed-in tariffs, ZEV solutions, and contracting models; depending on programme status, cantonal subsidies (e.g. for roof renovations or storage) are available on top. For private owners, Pronovo and the full tax deduction are the main pillars.

Permits and energy law

Roof-mounted systems on standard buildings in Geneva require notification but no permit. For listed objects, systems in the Zone de protection du vieux Genève, and facade installations on protected buildings, a building permit is required. The Office cantonal de l'énergie (OCEN) provides guidance. Geneva consistently implements MuKEn principles. New buildings and major renovations must meet self-generation requirements; heating replacements clearly favour renewables. PV systems combined with heat pumps or district heating complements are the recommended standard.
