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. That is exactly how we run solar projects – from the pre-check to documented commissioning.
Clarify before quoting
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 the initial estimate to handover.

Context
How this service works in Solothurn in practice.
Solothurn comes with its own framework conditions – from incentives and tax treatment to technical requirements. From those, a cleanly managed project flow for your property takes shape.
Service focus
What the full installation secures on site
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.
- 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.
Regional framework
Why this canton shifts the priorities
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. Feed-in via Regio-Energie Solothurn.
- 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.
Project logic
How coordination makes the difference
The order records these steps, responsibilities and required documents. Outstanding assessments belong in the schedule before work begins.
- Pre-check for roof, shading, electrical setup and potential constraints.
- Coordination of registration, metering concept and commissioning.
- Clean handover with traceable documentation for operations and service.
Regional context
Solar system installation in Solothurn: what matters here
In Canton Solothurn, cantonal rules, the responsible grid operator and local permit procedures shape how a project is planned and delivered. The points below show what really matters before quoting, installation and handover.
- Regional starting point
- In Canton Solothurn, incentives, grid operators and permit procedures change the priorities for this service.
- Service core
- A complete solar installation depends on sequencing, grid-operator coordination, electrical planning and clean commissioning.
- Grid & registration
- For Canton Solothurn, grid operators such as Regio-Energie Solothurn, metering concept and commissioning are aligned early.
- Decision reason
- In Canton Solothurn, a pre-check saves time when permits, metering or electrical setup are not standard.
- Execution
- Pre-check for roof, shading, electrical setup and potential constraints.
- Economic frame
- Feed-in tariff and self-consumption are matched to the property; in the canton, 9.0 Rp./kWh Winter, 4.0-6.20 Rp./kWh Sommer (je nach Anlagengroesse/Eigenverbrauch) + HKN 4.0 Rp./kWh (bis 30 kVA) / 1.0 Rp./kWh (ueber 30 kVA) (Regio Energie Solothurn 2026) is one relevant reference point.
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.
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. No general cantonal PV subsidy: through the Building Programme, Solothurn only funds the building envelope, heat pumps, wood heating and thermal solar — not PV electricity generation. For PV, the federal Pronovo one-time payment, individual municipal programmes and tax deductibility apply. Feed-in via Regio-Energie Solothurn. 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. Feed-in via Regio-Energie Solothurn. The cantonal Building Programme Solothurn funds energy renewal of the building envelope, heat pumps, wood heating and thermal solar — but not PV electricity generation. For photovoltaics, the federal Pronovo one-time payment applies; some municipalities (e.g., Olten) offer additional subsidies.
