Core service
Your complete PV system. From roof to grid.
Vigorek plans your system and installs the mounting structure and modules in the Zurich region, the Limmat Valley and eastern Aargau. An electrical contractor with an installation licence carries out the DC cabling, the connection of inverter and battery, and the AC connection. 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 14,500–23,300
Incl. 8.1% VAT, before incentives and tax deductions, without a battery. Calculated with the reference curve of the SFOE price survey (CHF 1,628 per kW plus CHF 5,278): 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.
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
Planning and installation of photovoltaics in the Zurich region, Limmat Valley and eastern Aargau. Electrical work by a partner with an installation licence.
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 handover.
- 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: two founders, one for engineering, one for finance. 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 and system integration. He has helped install systems on roofs himself and plans so that nothing has to be improvised on the roof.
Regional Expertise
Based in Oberengstringen, rules for your region.
Every region has its own regulations, subsidies, and grid operators. We know the local conditions and support your project perfectly tailored to your location.
