Your key details are enough for a first, honest orientation — no appointment, no obligation.

SOLAR · STORAGE · HEAT PUMPS
The Canton of Bern is among the most progressive cantons for solar energy: the solar mandate applies not only to new buildings but also to significant roof renovations. With additional subsidies for battery storage and dedicated energy consulting through the Bernese Energy Centre, switching to solar is especially worthwhile.
Services
PV system, heat pump, storage, wallbox and monitoring from one team. Every service is planned as part of a working energy system.

01 · Roof & facade
We review roof, structure, shading, cable routing, inverter and grid connection. Then we create a technically reliable quote.

Process
From first contact to commissioning, every system follows a clear process. We clarify roof, electrical work, incentives and expansion path completely. Only then do you receive a reliable quote. No site chaos, no wishful math.
System step
About 2 minutesYour key details are enough for a first, honest orientation — no appointment, no obligation.
System step
Response within 24–48 hWe measure the roof by drone and clarify electrical work, regulations and the grid operator.
System step
A few days after the surveyYou see every line item individually, realistic ranges and sensible options such as storage or a wallbox.
System step
After permit and grid-operator approvalWe coordinate execution, registration, acceptance and documentation until your system is reliably connected to the grid.
Swiss facts
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
We map self-consumption, feed-in tariff and payback for your property — so you see early what the system realistically returns.
Proof
Our quotes are not built from flat packages, but from checked data, technical pre-assessment and clearly itemized positions.
Planning basis
Roof potential, irradiation and addresses are checked against GeoAdmin and BFE Sonnendach: the same datasets used by federal and cantonal bodies.

Property review
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
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
Every line item is shown individually instead of hidden in a flat package — so variants and ranges stay traceable from the start.

Execution standard
Regional clarification
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
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.

Co-Founder · Strategy & Finance
Independent management consultant since 2015, previously Senior Manager at KPMG. Most recently Interim Treasury Manager at an energy storage manufacturer. Christian brings the financial structure: liquidity planning, transparent calculations and no project whose numbers don’t add up.

Marc handles the technical side: planning, structural analysis, system integration and execution that remains traceable a decade later. An engineering mindset means no improvisation, only well-reasoned solutions for every roof.
Questions about your roof? We’ll go through them with you personally — the initial estimate is the easiest way in.
Building in focus
Full-black, in-roof or flat-roof: in Bern we plan not for a datasheet, but for a building that has to stand up architecturally and within its local context.

Architecture first
In Bern, materiality, visual lines and technical details are aligned so the system fits the design language and performs cleanly over time.
Mounting, waterproofing, shading and electrical work are clarified on the actual building — not on a model.
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.
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.

Clarity before commitment
The key points are explained clearly, factually and without artificial urgency. For details, we assess your property in its project context.
Your key details produce a first orientation on price range, incentives and payback — a solid basis to talk through your project.
A realistic span for your roof — not a rounded sales promise.
Electrical scope, metering and grid connection belong to the calculation from the start, not to a surprise afterwards.
If it fits, a traceable quote follows. If it doesn’t, we’ll tell you that openly.

Core services
The key services, tailored directly to Bern and the local requirements in your region.
Regional service
Bern ranks among the cantons with the highest installed PV capacity per capita. BKW and EWB offer feed-in compensation up to 10.96 Rp./kWh (EWB). In the Bernese Oberland, altitude and snow reflection deliver up to 12% higher winter yields with bifacial modules – placing special demands on mounting structures and load distribution on alpine roofs.
View serviceRegional service
Canton Bern implemented MuKEn 2014 modularly and pursues one of Switzerland's most ambitious expansion goals with its cantonal solar initiative. New buildings over 300 m² mandatorily require a solar system. Coordination with BKW or EWB – depending on grid area – determines metering concept, feed-in regulation and commissioning flow. This requires project management that knows both utility processes.
View serviceIn Canton Bern, commercial buildings in the midlands and higher elevations in the Oberland present two fundamentally different flat-roof scenarios: in the midlands, standard structural analysis and quick approvals matter; in the Oberland, snow loads (SIA 261) and elevated wind exposure dominate. Bifacial modules on Oberland flat roofs exploit snow reflection – but require adapted mounting geometry.
