The greatest solar potential in canton Zug
National ranking →Baar has the greatest solar-energy potential in canton Zug: its roofs could generate about 132 GWh of electricity a year. Next come Zug (120 GWh) and Cham (88 GWh). This is modelled roof potential — largest where there is the most roof area, not current generation. Source: BFE.
Ranking
BFE · 2025How 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 Zug has the greatest solar potential?
- Baar, whose roofs could generate about 132 GWh of electricity a year (2025) — the greatest modelled roof potential of any municipality in canton Zug.
- 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.
