In Bern, the status of the building, the network and the roof potential must be clarified early. Check the site data and official sources before signing.
Decision to make
In Bern, the status of the building, the network and the roof potential must be clarified early. Adapt this decision to the building, your actual consumption and the project schedule.
For this project, start by identifying the grid operator, applicable tariff and site constraints. The quotation must specify the conditions affecting connection, metering or the value of surplus electricity.
Practical effects of the project
- An urban project may add constraints: roof access, shading, condominium decisions, visible facades and coordination with the electricity distributor.
- The public potential of the roof must be compared to existing equipment, chimneys, dormer windows, parapets and safety zones.
- The tariff confirmed by the grid operator and the treatment of surplus electricity must be stated explicitly in the calculation.
- In the city, collective projects, RCP/ZEV or LEG can be more important than a simple sale of surplus.
- The estimate must specify who manages announcement, connection, meter and possible co-ownership assembly.
These points help assess the topic ‘ Solar panels in Bern: BKW, approval and prices ’ without turning a national average into a local promise. Every decisive figure needs its source, date and scope.
Specific controls
- Confirm site data with the relevant professionals and connection conditions with the grid operator.
- Show base price, options, connection, aid and exclusions separately.
- Compare a reference hypothesis with a conservative variant before signing.
The answers should appear in the quote or in a dated appendix. A verbal explanation is insufficient if it changes the price, expected output, financial support or a contractual obligation.
Compare quotes
- Tariffs: state the purchase price, surplus remuneration and fixed charges applicable to the site, with their source and date.
- Production: provide a monthly estimate with orientation, shading, losses and weather assumptions.
- Investment: separate material, installation, safety, scaffolding, connection, procedures and options.
- Aids: distinguish confirmed amount, estimate and deposit liability.
- Contract: specify guarantees, calendar, deposit, exclusions, maintenance and after-sales service.
In Bern, the status of the building, the network and the roof potential must be clarified early. In the comparison table, keep one column for the stated value, one for the evidence provided, and one for the effect of a less favorable hypothesis.
Cautious scenario
Test the project with slightly lower production, an unconfirmed grant and less favourable surplus remuneration. This scenario shows whether the decision remains sound based on self-consumption, roof quality and a controlled installed cost.
The main references used are ElCom - Slight drop in electricity prices in 2026, Confederation - Sonnendach / solar potential of roofs, Energiefranken - Search for energy aid by municipality, SFOE - support for photovoltaic installations. They frame the method, but the local amounts and contractual conditions must be rechecked at the time the offer is signed.
Risks to be managed
The estimate must specify who manages announcement, connection, meter and possible co-ownership assembly. Ask who assumes this risk, what proof will be provided and how a change is handled after ordering.
A more expensive solution should meet a specific need in your project. Ask for a documented benefit and a separate price for each option.
Next step
Gather the address, annual consumption, future electricity uses and building documents. Then check the grid operator's conditions, available grants and site constraints; request quotations covering the same scope.
In Bern, the status of the building, the network and the roof potential must be clarified early. You can then decide with a documented net price, clear responsibilities and assumptions that each company can explain line by line.
A Bern example: renewing a commercial lease
Consider a tenant business planning solar when its lease is due for renewal. This is a contract-preparation example. Before comparing equipment, clarify roof access, use duration, installation ownership and what happens to equipment when the lease ends.
Request calculations for the secured period and a separate extension scenario. A twenty-year assumption must not hide a much shorter lease commitment. Show possible removal, agreed compensation and warranty transfer.
Then align the technical file with the chosen contract: meter, connection, network contact and surplus recipient. A familiar supplier name does not replace address verification or written commitments between landlord and business.
Points to check
- Tariffs: Compare the tariff for your address with the Swiss ElCom median for 2026, keeping local prices separate from the national benchmark.
- Grants: Check the programme, eligibility, documents and deadlines with Pronovo, the canton or municipality. Include only confirmed contributions in your budget.
- Roof potential: Sonnendach is presented as a public pre-diagnosis, to be validated by a technical visit.
- ROI: the method separates self-consumption, injection, installed price, taxation and payment schedule.
- An urban project may add constraints: roof access, shading, condominium decisions, visible facades and coordination with the electricity distributor.
- The public potential of the roof must be compared to existing equipment, chimneys, dormer windows, parapets and safety zones.
