Self-consumption
What a self-consumed kWh is worth in La Ferrière
On the standard tariff of Société des Forces Électriques de La Goule SA, a purchased kWh costs 22.45 ct in 2027 excluding fixed and metering fees. That is roughly what every kWh of solar power saves when it is used in the house instead of being exported. The total price is 2.02 ct below last year (29.93 ct).
Exported power is paid at the quarterly reference market price; since 2026, systems below 30 kW are guaranteed a minimum of 6 ct/kWh. In La Ferrière, self-consumed power is therefore worth up to 3.7 times as much as exported power — which is why the share of solar power used in the house matters most.
Winter power
How much solar power La Ferrière delivers in winter
Suitable roofs in La Ferrière could produce 10.6 GWh of solar power per year, 31% of it between October and March. Adding façades raises the potential to 14.6 GWh and the winter share to 34%: vertical surfaces make better use of the low winter sun.
For a house with a heat pump, this winter share is what matters: demand is highest in winter and self-consumption is most valuable. Whether a flatter or steeper layout pays off on your roof only becomes clear in the site assessment.
Uptake
How far La Ferrière has come with solar
The federal plant register lists 44 photovoltaic systems in La Ferrière with a combined 955 kW. Since January 2025, 8 systems with 176 kW have been added. The register covers all systems above 30 kVA, subsidised systems and voluntarily registered small systems; new systems often appear with a delay. Per resident that is 1,743 watts — rank 70 of 334 municipalities in the Canton of Bern.

Figures with sources
Solar in La Ferrière: cost, size, storage.
Three questions decide almost every project before a roof is ever measured. Here they are with source and date, so it stays clear what each figure rests on.
Costs
What a system costs
Example: 5–10 kWp rooftop PV: CHF 13,500–27,000. Incl. 8.1% VAT, before incentives and tax deductions, without a battery. Calculated from the SFOE median of CHF 2,497/kWp: the range reflects different system sizes. A market comparison, not a quote.
Roof renovation, structural reinforcement and replacement of the meter cabinet are not included. Roof access, electrical work and planning can change the price. Your specific quote follows the property assessment.
Costs with calculation and sourcesSizing
Single-family home: the realistic size
A typical household using around 4,000 kWh per year needs roughly 25 m² of module area (Swissolar, February 2024). As a starting figure, global irradiation in Canton Bern is around 1150 kWh/m² per year. Whether that works on your roof in La Ferrière depends on orientation, pitch and shading — not on the floor plan.
Two federal bonuses explicitly do not apply to a single-family home: the winter electricity bonus requires at least 100 kW, and the tilt bonus at least 75 degrees of pitch. Neither applies to an ordinary pitched roof. Counting on them makes the business case look better than it is.
Clarify notification and permission before installationStorage
Battery storage and self-consumption
Battery storage earns its money through self-consumption: it shifts solar power from midday into the evening. With Société des Forces Électriques de La Goule SA, every kWh shifted this way is worth 22.45 ct instead of a feed-in payment of at least 6 ct — up to CHF 165 per 1,000 kWh a year. Whether that covers the battery over its lifetime depends on your evening consumption.
Since 1 January 2025, an association for self-consumption (ZEV) may also use the existing connection lines. This makes apartment buildings and neighbourhood setups considerably cheaper, as no dedicated line is required. In La Ferrière, the connection conditions are set by Société des Forces Électriques de La Goule SA.

Swiss facts
Applies to residential and commercial properties.
- One-time remuneration
- Federal support depends on system type and size band. Vigorek clarifies which remuneration rate applies to your property and how it interacts with canton and grid operator.
- Storage as a system decision
- A battery only pays off when it fits your consumption and home technology. We assess it as part of the overall plan — not as a late upsell.
- Realistic payback
- We calculate with ranges instead of wishful numbers: self-consumption, remuneration and tariff logic together give a realistic picture of your economic return.
Economics
What does your solar system save?
We map self-consumption, feed-in tariff and payback for your property — so you see early what the system realistically returns.
Proof
How sound planning becomes visible.
Our quotes are not built from flat packages, but from checked data, technical pre-assessment and clearly itemized positions.
Planning basis
Official data as the first cross-check
Roof potential, irradiation and addresses are checked against GeoAdmin and BFE Sonnendach: the same datasets used by federal and cantonal bodies.
Property review
Final quote based on verified data
The initial estimate gives realistic orientation. For the final quote, we capture roof areas, access and technical conditions through a 3D survey (drone) and on-site review — precise, not based on satellite assumptions.
Electrical
Coordination by licensed professionals
From electrical planning through protection equipment to grid registration: all safety-critical steps are carried out by licensed electrical professionals, in-house or through vetted partners.
Quote
Itemized instead of a flat package
Every line item is shown individually instead of hidden in a flat package — so variants and ranges stay traceable from the start.
Execution standard
- Fall protection
- Waterproofing
- Electrical installation to standard
- Documentation
Regional clarification
Not every system follows the same logic in La Ferrière.
In Switzerland, permits, grid operator, metering concept and incentive path always depend on the property, municipality and canton. These are exactly the points clarified early before a quote becomes binding.
That avoids a generic promise and creates a well-founded assessment that fits the region and the building.

The key points are explained clearly, factually and without artificial urgency. For details, we assess your property in its project context.
Municipality check
Solar system in La Ferrière: what matters locally
For local PV projects, the municipal boundary is not the only factor: roof access, snow load, shading, meter cabinet and grid connection determine the project flow.
La Ferrière belongs to Canton Bern. We therefore combine the local roof assessment with cantonal requirements for subsidies, permits, grid connection and documentation.
Roof potential
Canton Bern guideline: approx. 1150 kWh/m² global irradiation per year.
Grid & utility
Grid operator in La Ferrière according to ElCom: Société des Forces Électriques de La Goule SA. Metering concept and registration are clarified before execution.
Permit
Roof-mounted systems in Bern require notification but no permit (if sufficiently adapted). In townscape protection zones or for cultural monuments, a building permit is required.
Subsidies & taxes
Bern has no cantonal PV top-up. What matters are the Pronovo one-time payment, municipal programs such as EWB in the City of Bern (CHF 80/kWp up to 30 kWp, then CHF 2,400 flat), and full tax deductibility. The winter electricity bonus only matters for large special-purpose systems above 100 kWp.

Helpful answers on solar in La Ferrière
These guides answer the questions that come up most often before deciding on a solar installation.
Solar Permit Bern
When a rooftop PV system in Canton Bern is permit-free, when only the eBau notification procedure applies, and which heritage and K-object exceptions trigger a building permit.
Pronovo one-time payment Bern
How high the Pronovo one-time payment for a PV system in Canton Bern is, how it splits into a base and a capacity payment, when to file the application, and how federal funding, the absence of cantonal PV funding and the tax deduction relate to each other.
Grid Operator Registration PV Bern
In canton Bern the responsible grid operator depends on the location: ewb in the city of Bern, BKW across most of the rest of the canton, plus local utilities such as Localnet (Burgdorf). The contractor submits a technical connection application (TAG) before construction; building is only permitted after approval.
Battery storage sizing – Bern
How big a PV battery storage system in canton Bern should be: sizing rules from Swissolar and SwissEnergy, a guide price of CHF 600-900/kWh, the ewb storage subsidy of CHF 100/kWh limited to the city area, and the duty to report retrofitted storage to Pronovo.
