Solar Installation Genf – Planning to Commissioning

Local system fit

For a solar installation in Genf, success depends not only on module area but on the process: 3D survey, transparent quote, grid-operator coordination and commissioning with full documentation. Vigorek handles the full coordination — from the initial estimate to handover.

Context

How this service works in Genf in practice.

Genf comes with its own framework conditions – from incentives and tax treatment to technical requirements. From those, a cleanly managed project flow for your property takes shape.

01Service 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. That is exactly how we run solar projects – from the pre-check to documented commissioning. From the initial estimate and 3D survey through a transparent quote to full commissioning — one project, one process, one contact.

Initial estimate and 3D survey (drone): 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.

02Regional framework

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, the SIG Prime solaire tops up the Pronovo one-time payment from 1 Jan 2026: 25% for systems of 2 to <30 kWc and 15% for 30 to 100 kWc. There is also an SIG battery storage contribution of CHF 130/kWh (max. 15 kWh) plus the full tax deduction. Register the application before construction starts – 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.

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.

Regional context

Solar system installation in Genf: what matters here

In Canton Genf, cantonal rules, the responsible grid operator and local permit procedures shape how a project is planned and delivered. The points below show what really matters before quoting, installation and handover.

Regional starting point

In Canton Genf, incentives, grid operators and permit procedures change the priorities for this service.

Service core

A complete solar installation depends on sequencing, grid-operator coordination, electrical planning and clean commissioning.

Grid & registration

For Canton Genf, grid operators such as SIG (Services Industriels de Genève), metering concept and commissioning are aligned early.

Decision reason

In Canton Genf, a pre-check saves time when permits, metering or electrical setup are not standard.

Execution

Pre-check for roof, shading, electrical setup and potential constraints.

Economic frame

Feed-in tariff and self-consumption are matched to the property; in the canton, 10.96 Rp./kWh fix (SIG, bis 100 kWc, 2026) is one relevant reference point.

Cantonal framework

Which cantonal framework shapes the project in Genf.

The technical service stays the same, but the project frame changes with the canton. That is exactly where incentives, tax treatment and MuKEn requirements become strategically relevant.

Local context

Genf sets the economic pace for this service.

Geneva is the only Romande canton with a dominant full-service utility: SIG bundles electricity, gas, water, district heating, and telecom. This greatly simplifies ZEV projects and neighbourhood solutions because all grid questions are answered by a single partner.

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). From 1 Jan 2026, the SIG Prime solaire tops up the Pronovo one-time payment: 25% for systems of 2 to <30 kWc and 15% for 30 to 100 kWc. There is also an SIG battery storage contribution of CHF 130/kWh (max. 15 kWh). The SIG feed-in tariff is a fixed 10.96 Rp./kWh in 2026 (systems up to 100 kWc). ZEV and contracting models apply 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 – the construction notice (avis d'ouverture de chantier) must be filed at least 14 days before work starts. 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; an OCEN subsidy request must reach the office at least 14 days before construction begins. 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.
