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 Gampelen.
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 Founders
Engineering depth. Financial structure.
You know before signing who calculates your project and who builds it. Behind that are two founders with two areas of expertise — engineering and finance — and the conviction that a solar system only works long-term when both fit together from the start.

Questions about your roof? We’ll go through them with you personally — the initial estimate is the easiest way in.
Building in focus
From roof surface to energy surface.
Full-black, in-roof or flat-roof: in Gampelen we plan not for a datasheet, but for a building that has to stand up architecturally and within its local context.
Transformation
Architecture first
Architecture, use and yield planned together.
In Gampelen, materiality, visual lines and technical details are aligned so the system fits the design language and performs cleanly over time.

Precision
Installation becomes visible before it has to be explained.
The system grows precisely into the building: tight penetrations, protected facade, modules sliding into the rails, and an aesthetic that fits the architecture instead of disturbing it.
Calm
Technology that stays calm after handover.
The inverter, registration and documentation are done, cable routes and labels stay traceable, and the roof becomes a calm, reliable energy source for everyday use.

Costs, storage, single-family home
Solar in Gampelen: the figures people ask about most
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
The federal one-time payment covers at most 30 % of the investment cost of a reference system. For roof-integrated systems it is roughly 10 % higher, because the roof skin is part of the investment. The application is filed after commissioning via the Pronovo portal.
Swissolar puts a roof-integrated 50 m² system at roughly CHF 20,000 — after the one-time payment and tax deductions (Photovoltaics factsheet, February 2024). The exact figure depends on roof build-up, access and electrical work, not on module area alone.
Sizing
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 Gampelen 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.
Storage
Battery storage and self-consumption
Battery storage earns its money through self-consumption. Electricity you use yourself saves not only the energy price but also grid fees and levies — which is why it is worth more than exported electricity. That is what decides whether a battery pays off.
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. Relevant grid operators in Canton Bern: BKW, EWB.

Municipality check
Solar system in Gampelen: 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.
Gampelen 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
Relevant grid operators in the canton: BKW, EWB. 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 Gampelen
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.
