Be aware, the following rules apply from 1.1.2026. If you have new system, or install a new inverter, the amount of power you feed back into the grid can be blocked during peak periods :
Grid Overload and Temporary Disconnections
On particularly sunny days, excessive solar power generation at midday can strain the electricity grid. To prevent costly infrastructure expansion, the revised Electricity Act allows solar installations to be temporarily disconnected from the grid during peak production times. The newly approved regulations, effective from 2026, limit these disconnections to a maximum of three percent of an installation’s annual production.
For homeowners with photovoltaic (PV) systems, this measure translates to an estimated financial loss of CHF 25 per year for an average single-family home. Industry representatives largely support this step, emphasizing its role in reducing future grid costs. According to the Association of Swiss Energy Companies (VSE), without such measures, grid-related expenses could reach CHF 9 billion per year by 2050—more than double today’s costs.
Adjustments to Minimum Solar Tariffs
While industry leaders accept the grid disconnection measure, they stress the importance of stable financial incentives to ensure continued investment in solar energy. The Federal Council has revised the minimum feed-in tariff for small solar installations, increasing it from 4.6 to 6 centimes per kilowatt-hour (Rp./kWh). However, medium-sized systems (30–150 kW) remain without a guaranteed minimum tariff, raising concerns among multi-family property owners and agricultural businesses.
Critics argue that the revised tariffs are still too low, particularly for larger rooftop installations with minimal self-consumption. According to the Swiss Energy Foundation, profitability remains a challenge unless producers can use a significant portion of their generated electricity themselves.
