Which municipality in canton Fribourg has the greatest solar potential?

Bulle FR, whose roofs could generate about 167 GWh of electricity a year (2025) — the greatest modelled roof potential of any municipality in canton Fribourg.

Does this mean the municipality actually produces this much solar power?

No. It is the modelled potential of the available roof surfaces — the electricity they could generate if fully used. Actual installed photovoltaics produce far less. The figure comes from the BFE solar model and scales with how much roof area a municipality has.

How we measure this

BFE

Modelled annual electricity that rooftop photovoltaics could produce across the whole municipality, in gigawatt-hours per year, from the BFE «Solarenergiepotenziale der Schweizer Gemeinden» model (2025 snapshot). It is a potential, not installed capacity or actual generation, and it scales with roof area — so large towns lead simply because they have more roofs. It is a rolling model snapshot, not an annual survey. The companion roofs-plus-façades scenario adds vertical surfaces.

Frequently asked questions

Which municipality in canton Fribourg has the greatest solar potential?: Bulle FR, whose roofs could generate about 167 GWh of electricity a year (2025) — the greatest modelled roof potential of any municipality in canton Fribourg.
Does this mean the municipality actually produces this much solar power?: No. It is the modelled potential of the available roof surfaces — the electricity they could generate if fully used. Actual installed photovoltaics produce far less. The figure comes from the BFE solar model and scales with how much roof area a municipality has.
