Core service

Every roof is different. Our installation too.

Switzerland crossed the 8 GW milestone for the first time in 2024 – 1.8 gigawatts of new solar capacity in a single year, enough electricity for 2 million households. Behind that figure lie enormous quality differences: faulty module fixing, inadequate earthing and poor cable management are among the most common defects according to industry experts. PV installation is the interaction of roof membrane, mounting structure, cable routing, safety and a handover that remains traceable ten years later. Vigorek prepares a mounting concept before the first material is ordered.

System logic

Mounting structure per SIA 261, documented penetrations, SUVA-compliant fall protection and complete handover including string diagram, measurement protocol and photo documentation.

Scope of service

What you can expect from us.

Transparency from initial planning to completed installation. We show you exactly which steps we handle and what matters most during execution.

01
Scope of work

What this service concretely covers.

The scope is structured so roof work, electrical work, day-to-day use and future upgrades stay aligned. That is what creates a cleaner execution.

Scope of work

  • Mounting structure matched to tile, sheet metal, facade or flat-roof systems – not generic, but dimensioned object-specifically to wind zone (SIA 261), snow loads and building height.
  • Clean cable routing with documented penetrations and roof membrane protection. Every transition between roof and electrical installation is photographed and recorded.
  • Coordination of scaffolding, fall protection (SUVA-compliant), installation logistics and object-specific safety requirements – including a mounting concept prior to material ordering.
  • Photo documentation and traceable handover: single-line diagram, string plan, data sheets, measurement protocol, photos – everything needed for acceptance, grid operator and future service.
02
Why this is chosen

Where owners and operators feel the difference.

This service becomes relevant when not only the result matters, but also ownership, traceability and a dependable project flow.

Why this is chosen

  • Mounting concept before material ordering – not improvisation on the roof.
  • Clear responsibilities: roofer, electrician, project management. No single-person-does-everything approach.
  • Safety verification (SiNa) per SN EN 62446-1 by a certified specialist – mandatory from 2 kWp under NIN 2025 Chapter 7.12.
  • DC connectors from the same manufacturer per NIN 2025, Chapter 7.12.5.2.6 – applied consistently, not only on new installations.
03
Typical application

Which projects this service fits especially well.

Not every building needs the same execution depth. These examples show where this service makes the biggest difference.

Typical application

  • Single-family homes with high aesthetic standards (full-black, in-roof), clean cable routing and long-term value preservation.
  • Renovations and roof refurbishments where PV installation and roofing work must be planned simultaneously.
  • Commercial roofs with complex access, multiple roof penetrations and elevated documentation requirements (e.g. for insurers or authorities).

The Founders

Engineering depth. Financial structure.

Two founders, two domains of expertise – one shared conviction: solar installations work long-term only when engineering and business case fit together from the start.

Regional page

Aargau

Aargau is known as the "energy canton" – with PSI (Paul Scherrer Institute) in Villigen researching solar technologies and PARK INNOVAARE as an innovation cluster. AEW Energie AG compensates feed-in at 11.15 Rp./kWh (2025, including HKN). The high density of industrial and commercial buildings offers enormous potential for large rooftop systems. Additionally, the canton supports battery storage with dedicated contributions.

Regional page

Basel-Landschaft

In Basel-Landschaft, EBL and Primeo Energie compete with notably different compensation rates (Primeo: 10.5 Rp./kWh + 2.5 Rp. HKN, EBL: market-based from ~3 Rp.). The Baselbieter Energiepaket 2026–2030 provides CHF 51.25 million with bonus contributions for combined roof/facade renovations with PV. Sunny locations in the Ergolz valley and southern Jura slopes deliver irradiation values comparable to the Zurich region.

Regional page

Basel-Stadt

Basel-Stadt pursues the ambitious net-zero 2037 climate target. The solar offensive mandates PV systems on new buildings and gradually extends the obligation to existing buildings (15-year transition). IWB compensates feed-in at 14 Rp./kWh – one of Switzerland's highest tariffs. On the dense urban roofscape, every square metre of mounting area and execution precision count.

Regional page

Bern

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.
