The greatest solar potential per capita in canton Obwalden

National ranking

Lungern has the greatest solar potential per capita in canton Obwalden: its roofs could generate about 10'385 kWh of electricity a year per inhabitant. Next come Giswil (10'254 kWh) and Engelberg (8'771 kWh). Per capita, small municipalities with lots of roof area — barns and sheds — lead, not the big cities. Source: BFE/FSO.

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 Obwalden has the greatest solar potential per capita?
Lungern: its roofs could generate about 10'385 kWh of electricity a year per inhabitant (2025) — the greatest modelled per-capita potential of any municipality in canton Obwalden.
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.
