Core service

One process. From roof to grid.

The best module technology is of little use if metering concept, grid-operator registration and electrical planning are not coordinated. That is exactly where most projects fail — not on hardware, but on loose interfaces between roof, electrical work and administration. Vigorek structures every installation as a seamless process: from technical pre-check through a transparent quote to commissioning with full documentation. One project, one process, one contact.

In short

From the initial estimate and 3D survey through a transparent quote to full commissioning — one project, one process, one contact.

No standard price – every roof is different. The configurator gives you an individual estimate.

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, PV installation, electrical coordination and commissioning across German-speaking Switzerland.

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.

01Scope 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.
02Why 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 work by ESTI-certified professionals: from electrical planning and protection concept through to grid registration.
  • In many cantons a notification procedure with a 30-day waiting period is sufficient — we know the cantonal requirements before the quote is issued.
03Typical 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.

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.

Regional fit

Our experience in your region.

Whether it's building permits, cantonal subsidies or registration with the local grid operator: a smooth execution requires local knowledge. Find specific information for your area here.

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. AEW Energie AG compensates at 11.15 Rp./kWh (including 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 14 Rp./kWh feed-in compensation. 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.
