Which municipality in canton Jura has the greatest solar potential per capita?

Ederswiler: its roofs could generate about 35'495 kWh of electricity a year per inhabitant (2025) — the greatest modelled per-capita potential of any municipality in canton Jura.

Why do small municipalities lead rather than the cities?

Because the roof potential is divided by the number of inhabitants: few residents with large barn, shed and stable roofs produce high per-capita values. Big cities have the greatest absolute potential but little roof area per person. The figure remains modelled potential, not today's generation.

How we measure this

BFE + BFS

Modelled annual rooftop electricity yield (BFE solar model, 2025 snapshot) divided by the permanent resident population (FSO STATPOP), in kilowatt-hours per year per inhabitant. For scale: an ElCom reference household (profile H4) uses 4,500 kWh a year. It is a potential, not installed capacity or actual generation. Per capita the absolute ranking inverts: small municipalities with large barn and shed roofs lead, not the cities with the most total roof area.

Frequently asked questions

Which municipality in canton Jura has the greatest solar potential per capita?: Ederswiler: its roofs could generate about 35'495 kWh of electricity a year per inhabitant (2025) — the greatest modelled per-capita potential of any municipality in canton Jura.
Why do small municipalities lead rather than the cities?: Because the roof potential is divided by the number of inhabitants: few residents with large barn, shed and stable roofs produce high per-capita values. Big cities have the greatest absolute potential but little roof area per person. The figure remains modelled potential, not today's generation.
