In 2026, the Swiss median household prices will fall, but prices remain very variable depending on the municipality and the DSO. Discover the concrete impact on the profitability of your solar installation.
Swiss households have received their pricing notices for 2026: the average increase is 8%, with peaks of 12-15% in certain cantons. This trend, which began in 2021, is radically transforming the calculation of the profitability of solar installations.
Why are prices increasing? Three factors converge: the cost of distribution networks (aging, requiring massive investments for the integration of renewables), the price of electricity on the European market (on which Switzerland is partially dependent despite its dams), and various fees (network supplement financing Pronovo, cantonal taxes).
Concrete impact on the solar ROI. The effect must be recalculated with the rate of your municipality: the more expensive the kWh purchased, the more value each self-consumed kWh has. Use your current invoice, your DSO's injection rate and a production simulation rather than a generic ROI.
What the experts anticipate. ElCom publishes prices by municipality and by DSO; it is this local value which must power the solar calculation. This trajectory makes the solar installations installed today even more profitable over their lifespan.
Should we wait for a drop? No. Solar panel costs have bottomed out — an additional 5% drop doesn't make up for an entire year of high-rate bills. Every month of waiting is a year of lost high-rate production.
