PV in Canton Schwyz – low taxes, strong yields
The Canton of Schwyz combines one of the lowest tax burdens in Switzerland with attractive conditions for solar systems. Thanks to the full tax deduction and good irradiation values in Central Switzerland, investing in photovoltaics is especially lucrative here.
Local fact: Schwyz is seeing strong growth in private PV systems, especially in municipalities around Lake Zurich and the March district. The Schwyz high valley also offers good conditions for winter electricity production.Built to Swiss standards (NIN/ESTI)Free & non-bindingData stays confidential
Services
What we offer.
PV system, heat pump, storage, wallbox and monitoring from one team. Every service is planned as part of a working energy system.
01 / 05
01 · Roof & facade
Plan and install PV systems cleanly.
We review roof, structure, shading, cable routing, inverter and grid connection. Then we create a technically reliable quote.

01 / 05
Process
Understand first, then promise.
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.
02
System step
Response within 24–48 h3D survey & technical review
We measure the roof by drone and clarify electrical work, regulations and the grid operator.
03
System step
A few days after the surveyTransparent quote
You see every line item individually, realistic ranges and sensible options such as storage or a wallbox.
04
System step
After permit and grid-operator approvalPlanning, installation & commissioning
We coordinate execution, registration, acceptance and documentation until your system is reliably connected to the grid.
Swiss facts
Residential·Commercial
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 Schwyz.
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.

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.

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 Schwyz 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 Schwyz, materiality, visual lines and technical details are aligned so the system fits the design language and performs cleanly over time.

Substance
The roof leads, not the sales graphic.
Mounting, waterproofing, shading and electrical work are clarified on the actual building — not on a model.
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.

The key services, tailored directly to Schwyz and the local requirements in your region.
Regional service
PV Installation Schwyz – Roof & Electrical
Schwyz is seeing strong growth in private PV systems, especially in the growing agglomeration around Lake Zurich and the March district. EWS AG offers approximately 12 Rp./kWh – one of the highest feed-in compensations in German-speaking Switzerland. In the Schwyz high valley, systems deliver significantly more winter electricity thanks to altitude – installation quality must withstand alpine wind loads and snow conditions.

Solar Installation Schwyz – Planning to Commissioning
Canton Schwyz is growing – especially around Lake Zurich and in the March district. EWS AG (Axpo subsidiary) compensates feed-in at approximately 12 Rp./kWh and supports alpine solar projects. The failed referendum on the Alpin Solar Ybrig project (2024) shows: community engagement and transparent communication are as decisive in Schwyz as technical excellence.
View serviceIn Canton Schwyz, flat roofs on commercial buildings and multi-family homes represent the largest untapped solar area. Schwyz has implemented parts of MuKEn 2014. New buildings have self-generation requirements. The canton relies on a mix of personal responsibility and targeted regulation, with PV systems being the easiest compliance solution.
