Solar Installation Solothurn – Planning to Commissioning

In Canton Solothurn, owners usually want a clear project flow from first assessment to handover rather than a loose mix of subcontractors. This page is built for that intent.

Local system fit

Solothurn prioritises incentives over mandates in energy policy. The seasonal tariff from Regio Energie (winter 9.0 Rp., summer 4.0–6.2 Rp.) creates a natural incentive for self-consumption optimisation and storage integration. The canton ranks 3rd nationally in solar thermal subsidy density – a sign of a mature, technology-savvy solar market on the southern Jura slopes.

For a solar installation in Solothurn, success depends not only on module area but on the process: 3D survey, transparent quote, grid-operator coordination and commissioning with full documentation. Vigorek handles the full coordination — from initial assessment to handover.

Service focus

What the full installation secures on site

In Canton Solothurn, owners usually want a clear project flow from first assessment to handover rather than a loose mix of subcontractors. This page is built for that intent. From initial assessment and 3D survey through a transparent quote to full commissioning — one project, one process, one contact.

Service focus

  • Initial assessment and 3D drone survey: 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.

Neuendorf — Solothurn's solar champion: 12,329 kWp, 27.2% utilization (Swiss top). City of Solothurn: 8.2%. Total potential >3,000 GWh/year, currently only 11.2% utilized. Regio-Energie: 15 Rp./kWh — most attractive tariff in the region.

Regional framework

  • In Canton Solothurn, a pre-check saves time when permits, metering or electrical setup are not standard.
  • Owners want traceable quotes instead of aggressive package promises.
  • A documented commissioning reduces later questions and service overhead.

Cantonal framework

Which cantonal framework shapes the project in Solothurn.

The technical service stays the same, but the project frame changes with the canton. That is exactly where incentives, tax treatment and MuKEn requirements become strategically relevant.

Local context

Solothurn sets the economic pace for this service.

The Canton of Solothurn was one of the first cantons to fully implement MuKEn 2014. The southern Jura slopes around Solothurn and Grenchen benefit from above-average sunshine hours and ideal southern exposure.

Solothurn prioritises incentives over mandates in energy policy.

Tax and subsidy logic

In the Canton of Solothurn, PV investments are fully deductible as property maintenance. Energy-saving measures can also be spread over two consecutive tax periods if the deduction exceeds taxable income in one year. Municipally variable: subsidies through individual municipalities. Regio-Energie Solothurn: most attractive feed-in tariff in the region with 15 Rp./kWh. Tax deductibility. Neuendorf: model example with 27% utilization rate.

Permits and energy law

30-day notification before construction. eBau portal available for digital submission. Normal notification procedure for roof systems. Solothurn implemented MuKEn 2014 as of 2017 – as one of the first cantons. The cantonal energy law requires a high share of self-generated electricity for new buildings and mandates switching to renewable systems when replacing heating.

Market signal and location

Neuendorf — Solothurn's solar champion: 12,329 kWp, 27.2% utilization (Swiss top). City of Solothurn: 8.2%. Total potential >3,000 GWh/year, currently only 11.2% utilized. Regio-Energie: 15 Rp./kWh — most attractive tariff in the region. Solothurn offers subsidies for energy renewal of the building envelope including PV through the cantonal Building Programme. Pronovo one-time payment and cantonal contributions are cumulative. Some municipalities (e.g., Olten) offer additional subsidies.
