Einsiedeln has the greatest solar-energy potential in canton Schwyz: its roofs could generate about 126 GWh of electricity a year. Next come Schwyz (116 GWh) and Küssnacht (91 GWh). This is modelled roof potential — largest where there is the most roof area, not current generation. Source: BFE.

How we measure this
BFEModelled 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 Schwyz has the greatest solar potential?
- Einsiedeln, whose roofs could generate about 126 GWh of electricity a year (2025) — the greatest modelled roof potential of any municipality in canton Schwyz.
- 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.
