Meyrin, Vernier, Grand-Saconnex, Satigny, Bellevue — from vineyard slopes to industrial estates.
The Geneva right bank blends two worlds we know well: the residential and wine-growing slopes of Pregny, Genthod, Collex-Bossy and Satigny on one side, and the dense fabric of Meyrin, Vernier and the ZIMEYSA industrial estate on the other. We work here on both individual homes and large commercial rooftops. From our base in Rolle, the right bank is 35 minutes away by motorway — with no call-out charge for quotes.
Service area
Local context
Geneva basin with a Lake Geneva climate: 1500 to 1700 hours of sunshine a year, solar output of 1000 to 1100 kWh/kWp depending on orientation. Mild winters let air/water heat pumps run without significant electric backup. The bise (north-easterly wind) must be factored into mounting loads, especially on the exposed rooftops of the slopes.
Sharp contrast between the affluent villas of the lakeside slope (Pregny-Chambésy, Genthod, Bellevue), the wine-growing villages of the Mandement (Satigny — the largest wine-growing municipality in Switzerland —, Dardagny, Russin) and the large industrial and logistics volumes of Meyrin-Satigny (ZIMEYSA). These flat commercial rooftops offer considerable, often under-used, solar potential.
Grid operator: SIG (Services Industriels de Genève). Geneva requires a building permit (fast-track APA procedure) for most solar installations, including residential ones — a file we prepare and submit for you. Typical SIG connection times: 4 to 8 weeks.
I.ON advice
The industrial and logistics halls of the Meyrin-Satigny zone have vast flat rooftops ideal for high-volume self-consumption. With Geneva's energy law pushing for solar equipment on buildings, now is the time to study a project — payback is often under 8 years thanks to daytime consumption.
Unlike Vaud, Geneva requires a permit (APA) for most PV installations. This adds 4 to 8 weeks to the schedule. We systematically include this step in our quote to avoid any nasty timing surprises.
In Pregny-Chambésy, Genthod or Bellevue, the lakeside zones and character villas call for discreet integration. We favour full-black modules or in-roof systems to make permits easier to obtain.
2026 subsidies
Federal grant for any new PV installation: around 320-380 CHF/kWp for small systems (<30 kWp), paid once after commissioning. For an 8 kWp system: ~3,000 CHF.
The canton of Geneva supports solar and, above all, the replacement of fossil-fuel heating with a heat pump through its cantonal programme (GEnergie / éco21). Grants for a heat pump replacing an oil or gas boiler are among the most generous in French-speaking Switzerland.
The net cost after subsidies is deductible from taxable income as an energy investment. The tax saving depends on your marginal rate and stacks with cantonal and federal subsidies.
Exact amounts vary from year to year and depend on the specifics of each project. We always calculate the maximum combination of grants available when preparing your quote.
Frequently asked questions
Yes. Meyrin, Vernier, Grand-Saconnex, Satigny and the entire right bank are within our service area. At 35-45 km from our base in Rolle (about 35 minutes on the A1), we charge no call-out fee for quotes or for warranty work.
In most cases, yes: Geneva requires a fast-track building permit (APA) even for residential installations, unlike canton Vaud where many projects are exempt. We handle the full file and submit it to the building authority. Allow 4 to 8 weeks for the procedure.
On a well-oriented roof (south, 30° pitch), expect 1000 to 1100 kWh/kWp per year, comparable to the rest of the Lake Geneva arc. The large flat industrial rooftops of the Meyrin-Satigny zone, fitted with optimised mounting, achieve excellent daytime self-consumption yields.
