Solar
Produce your own energy: up to 70% autonomy, CHF 300–600 per kWc via Pronovo, payback in 6-10 years.
Electricity prices in Switzerland keep rising while solar installations are more profitable and better subsidized than ever. A photovoltaic system covers up to 70% of your electricity needs, saving CHF 1,000–3,000 annually.
Federal subsidy via Pronovo (one-time feed-in remuneration): a CHF 700 flat fee plus CHF 300–600 per kWc installed. Average payback in 6-10 years, panel lifespan 25-30 years. Immediate bill reduction, price-hike protection, potential income from surplus feed-in.
New leverage in 2026: pairing with a storage battery. Several cantons (Geneva, Neuchâtel) now subsidize batteries up to CHF 130/kWh. Energy storage, stronger independence, optimized self-consumption in the face of lower buyback tariffs.
