PV Installation Bern – Roof & Electrical

People looking for PV installation in Canton Bern compare more than modules. They compare execution quality, roof protection and coordination. That is why this page focuses on the points that matter before quoting and installation.

Local system fit

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.

For Bern we plan PV installations object-specifically: mounting structures per SIA 261, SUVA-compliant fall protection and complete handover documentation before the system goes live.

Service focus

What really matters for installation on site

People looking for PV installation in Canton Bern compare more than modules. They compare execution quality, roof protection and coordination. That is why this page focuses on the points that matter before quoting and installation. Mounting structure per SIA 261, documented penetrations, SUVA-compliant fall protection and complete handover including string diagram, measurement protocol and photo documentation.

Service focus

  • 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

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. Bern is #1 in Switzerland for installed solar capacity. The Emmental and Bernese Oberland offer ideal conditions: large agricultural rooftops, high self-consumption, and the winter electricity bonus make solar on farms especially profitable. BelpmoosSolar produces 35 GWh/year.

Regional framework

  • In Canton Bern, 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

In the Canton of Bern, all costs of a PV system (including battery storage) can be fully deducted as property maintenance. The deduction applies to both first-time installations and replacements and can be spread over several tax periods. Mounting structure and scaffolding planned around roof type and access.

Project logic

  • 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.

Cantonal framework

Which cantonal framework shapes the project in Bern.

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

Bern sets the economic pace for this service.

Bern has one of the highest installed PV capacities per capita in Switzerland. The Bernese Oberland offers particularly high winter yields thanks to altitude and snow reflection – ideal for year-round solar production.

Tax and subsidy logic

In the Canton of Bern, all costs of a PV system (including battery storage) can be fully deducted as property maintenance. The deduction applies to both first-time installations and replacements and can be spread over several tax periods. Bern has no cantonal PV top-up. What matters are the Pronovo one-time payment, municipal programs such as EWB in the City of Bern (CHF 80/kWp up to 30 kWp, then CHF 2,400 flat), and full tax deductibility. The winter electricity bonus only matters for large special-purpose systems above 100 kWp.

Permits and energy law

Roof-mounted systems in Bern require notification but no permit (if sufficiently adapted). In townscape protection zones or for cultural monuments, a building permit is required. Bern has fully implemented MuKEn 2014 since 2023. The revised Bernese Energy Act (KEnG) mandates solar installation for new buildings and significant roof renovations above 50 m². Additionally, heating replacements must switch to renewable energy sources.

Market signal and location

Bern is #1 in Switzerland for installed solar capacity. The Emmental and Bernese Oberland offer ideal conditions: large agricultural rooftops, high self-consumption, and the winter electricity bonus make solar on farms especially profitable. BelpmoosSolar produces 35 GWh/year. For photovoltaics, there is no cantonal add-on bonus in the Canton of Bern. The main elements are the Pronovo one-time payment, municipal add-on programs (for example EWB in the City of Bern or Ittigen), and full tax deductibility. Cantonal battery grants are not part of the standard PV support logic.

Primary

PV Installation Solothurn – Roof & Electrical

Canton Solothurn: 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. Here owners can find the services that matter most for planning, installation and commissioning in this region.

Primary

PV Installation Aargau – Roof & Electrical

Canton Aargau: Aargau is known as the "energy canton" – with PSI (Paul Scherrer Institute) in Villigen, which also researches solar technologies. The high density of industrial and commercial buildings offers enormous potential for large rooftop systems. Here owners can find the services that matter most for planning, installation and commissioning in this region.

Secondary

PV Installation Wallis – Roof & Electrical

Canton Wallis: Valais has the highest solar irradiation in Switzerland – Sion counts over 2,100 sunshine hours per year. Alpine systems like those on the Muttsee dam wall or at Gornergrat demonstrate the enormous potential for winter electricity production in the Valais Alps. Here owners can find the services that matter most for planning, installation and commissioning in this region.
