Core service
Your complete PV system. From roof to grid.
Vigorek plans and delivers complete PV systems across all German-speaking cantons: solar modules, inverter, roof installation, electrical coordination and commissioning. Battery storage and a wallbox can be planned around your consumption. Your quote defines the scope and responsibilities.
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.
SFOE price survey 2025 · 03 Aug 2026 · Calculation and limitations
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.
Project profile
Typical use case
Owners who want central coordination instead of many separate contractors and open interfaces — one project, one process, one contact.
Coverage
Complete PV systems with planning, installation, electrical coordination and commissioning across all German-speaking cantons.
Contact
Before your enquiry
Three decisions. One clear quote.
For property owners planning a new PV system. For an extension, tell us about the existing components – the new-system cost example cannot be applied directly.
What belongs in the quote?
Compare the same capacity and scope: modules, inverter, mounting system, electrical materials, site safety, labour, planning and logistics. Ask for the battery, wallbox and necessary building work to be listed separately.
Understand costs and quote itemsNotification or planning permission?
The procedure depends on the building, location and protection requirements. Clarify notification with the municipality and connection with the grid operator before work starts. Our guide connects the national overview with cantonal rules.
Check the permission process for my projectPlan a battery at the same time?
A battery is a separate decision. Compare investment, usable capacity, consumption and local tariffs with and without storage. Greater independence does not automatically mean a higher return.

Service in detail
What you can expect from us.
From planning to handover: the scope, the standards behind it and the projects this service is made for.
Scope of work
What we concretely handle.
From substructure to handover, every step is defined before the first material reaches the roof.
What’s included
- Initial estimate and 3D survey (drone): roof, orientation, shading, electrical setup and possible constraints — before any quote is prepared.
- Transparent quote with clearly separated line items: material, installation, scaffolding, electrical, registration, commissioning — each one individually listed.
- Coordination of Pronovo registration, metering concept, grid-operator queries and meter replacement through to full commissioning.
- Optional integration of battery storage, wallbox and energy management — only where the usage profile and expansion goals support it.
Why this is chosen
How you recognise clean work.
It is not the result alone that counts, but ownership, compliance and a traceable process.
Dependable standards
- No blanket yield promises — ranges only after the 3D survey, because self-consumption rate, feed-in tariff and billing logic vary by property, canton and grid operator.
- No hidden items: material, installation, scaffolding, electrical and registration are listed individually — for genuine comparability.
- Electrical planning, protection concept and grid registration are part of the project — signed off by a licensed electrical professional.
- Notification or permit procedures and grid connection are checked for your location; deadlines and required documents depend on the municipality, canton and grid operator.
Typical application
Where this service makes the difference.
Not every roof needs the same depth – these projects benefit the most.
Especially fits
- Owners who want central coordination instead of many separate contractors and open interfaces — one project, one process, one contact.
- Projects involving incentive questions, grid-operator topics, metering concepts or several technical variants such as storage, wallbox or heat pump.
- Buildings where schedule reliability, clear communication and a commissioning without loose ends are decisive.
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.
Christian Freiberger
CFA · former KPMG Senior Manager
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 Hammerschmidt
B.Eng. Mechanical Engineering
Co-Founder · Engineering & Planning
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.
Regional Expertise
Locally rooted, experienced nationwide.
Every region has its own regulations, subsidies, and grid operators. We know the local conditions and support your project perfectly tailored to your location.
Priority region
Aargau
Aargau is among the few cantons that did not proactively implement MuKEn 2014 – but since 2025, the federal solar obligation applies for new buildings over 300 m². From 2026 AEW Energie AG pays a fixed tariff of around 8.2 Rp./kWh including HKN or the BFE reference market price without HKN. The canton pioneers agri-PV: four pilot projects generate up to 2.2 GWh/year. Spatial planning adjustments (July 2022) enable agri-PV on agricultural land – a regulatory framework unique in Switzerland.
Priority region
Basel-Landschaft
Basel-Landschaft benefits from dual-utility competition: EBL and Primeo Energie offer different compensation and service models. Since 2025, the canton's high-resolution solar cadastre is available online – with laser data for precise yield forecasts. MuKEn 2025 mandates at least 20 W/m² for new buildings and 10 W/m² installed capacity for roof renovations.
Priority region
Basel-Stadt
IWB (Industrielle Werke Basel) offers contracting models where owners bear no upfront investment alongside the market-based feed-in compensation that applies from 2026 (BFE reference market price, statutory minimum 6 Rp./kWh up to 30 kW, guarantees of origin handled separately). From 2026, Local Electricity Communities (LEG) enable cross-property electricity sharing with reduced network fees. The city's solar potential is 800 GWh/a – approximately 60% of electricity demand. Project management must unite urban site logistics, heritage assessment and LEG readiness.
Priority region
Bern
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.
