PV Installation Solothurn – Roof & Electrical
People looking for PV installation in Canton Solothurn compare more than modules. They compare execution quality, roof protection and coordination. Exactly these points decide on a clean result before quoting and installation.
Clarify before quoting
Canton Solothurn was among the first to fully implement MuKEn 2014. Regio Energie Solothurn offers seasonally differentiated compensation: 9.0 Rp./kWh in winter, 4.0–6.2 Rp./kWh in summer. This structure rewards winter production and makes storage economical. The southern Jura slopes around Solothurn and Grenchen benefit from above-average sunshine hours and ideal southern exposure.
For Solothurn we plan PV installations object-specifically: mounting structures per SIA 261, SUVA-compliant fall protection and complete handover documentation before the system goes live.

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 really matters for installation on site
Mounting structure per SIA 261, documented penetrations, SUVA-compliant fall protection and complete handover including string diagram, measurement protocol and photo documentation.
- 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.
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, roof type, access and cable routing need to be clarified early so installation does not turn into change orders.
- Owners compare execution quality, roof protection and clear ownership more than simple price promises.
- Site logic directly affects timing, appearance and future maintenance.
Project logic
How roof, installation and electrical work fit together
The order records these steps, responsibilities and required documents. Outstanding assessments belong in the schedule before work begins.
- Mounting structure and scaffolding planned around roof type and access.
- Clean penetrations, orderly cable routing and documented handover.
- Aligned workflow between installation, electrical work and commissioning.
Regional context
PV 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
- Installation quality is decided before site work starts: roof access, mounting structure, cable routing and fall protection need to be planned together.
- Grid & registration
- For Canton Solothurn, grid operators such as Regio-Energie Solothurn, metering concept and commissioning are aligned early.
- Decision reason
- In Canton Solothurn, roof type, access and cable routing need to be clarified early so installation does not turn into change orders.
- Execution
- Mounting structure and scaffolding planned around roof type and access.
- 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.
