If you have solar panels, the electricity you do not use goes into the grid and your grid operator buys it from you. On 1 January 2027, the way this price is calculated changes: it will follow the market price at the time of feed-in. Here is what applies today, what changes, the minimum guarantee that remains, and how to make the most of it.
What has applied since 1 January 2026
Under the federal act on a secure electricity supply from renewable energy, solar electricity fed into the grid is taken up by the operator of the grid to which the system is connected. Without agreement on the price, remuneration follows the average market price over a quarter (Energy Act, Art. 15, in French), with minimums set by ordinance:
| Photovoltaic system | Minimum remuneration |
|---|---|
| Under 30 kW | 6 cents/kWh |
| 30 kW or more, with self-consumption | Weighted value: 6 cents/kWh for the share under 30 kW, 0 above |
| 30 kW or more, without self-consumption | 6.2 cents/kWh |
Source: Energy Ordinance, amendment of 19 February 2025, Art. 12 (in French). For a detached house, the system is almost always under 30 kW: the minimum is therefore 6 cents/kWh.
What changes on 1 January 2027
On 27 May 2026, the Federal Council adopted the amendments that enter into force on 1 January 2027 (Energy Ordinance, AS 2026 298; Energy Act, AS 2026 297, both in French):
- A price that follows the time of feed-in. Remuneration equals the Swiss day-ahead spot market price at the moment you feed in. According to the Swiss Federal Office of Energy, this means the hourly price at first, and the quarter-hourly price in future (SFOE explanatory report, in French).
- The minimum remains guaranteed. For systems under 150 kW, if the average reference market price over a quarter is below the minimum, you receive the difference as a premium. The minimum amounts do not change.
- A transition for existing systems. Systems not yet fitted with a smart meter keep the old quarterly calculation until 31 December 2027 at the latest.
- A fixed price remains possible. These rules only apply if you and your grid operator do not agree on a price: an agreed fixed remuneration remains allowed.
- Small plug-in systems without a smart meter can be remunerated with an annual flat fee set by the grid operator.
From 1 January 2028, all production systems subject to the purchase obligation must be fitted with a smart metering system (Electricity Supply Ordinance, Art. 8a, in French).
How to make the most of it
Use more of your own electricity
Running the heat pump, the water heater or the electric car charger during production hours is worth more than feeding in at a low price. For a battery, the network-usage charge on electricity drawn, stored and fed back is refunded on request since 1 January 2026.
Aim for winter production
An east-west orientation, a steeper tilt or façade panels produce more when electricity is worth more. Since 1 January 2026, façade systems need no building permit — a simple notification is enough — when they meet the conditions of the Spatial Planning Ordinance (SPO, Art. 32abis, in French).
Share with your neighbours
Since 1 January 2026, a local electricity community can sell electricity between neighbours in the same municipality and at the same grid level, with a 40% reduction in the network-usage tariff (20% if a voltage transformation is needed) (Electricity Supply Act, Art. 17d, in French).
Compare your grid operator's offer
Ask your grid operator for its 2027 feed-in tariff and whether it offers a fixed price: depending on your production profile, it may be more attractive than the market price.
What about the one-off remuneration?
The one-off remuneration paid by Pronovo at installation remains the main support for a detached house. The new winter bonus, in force since 1 January 2026, only covers systems of 100 kW or more (Federal Council, in French; Pronovo, in German). For systems under 30 kW, a draft put out to consultation in spring 2026 provides for a higher one-off remuneration from 1 April 2027; nothing had been adopted as of 15 October 2026 (Federal Council, in French). Several cantons and communes add their own support: estimate it with the subsidy calculator.
If you are building or renovating your roof, a solar installation may also be mandatory: see our guide to the solar obligation.
Before fitting panels on a façade or a visible roof, also check what the plot allows: a protected perimeter, a heritage-listed building or an easement can restrict the installation, and these restrictions often appear in the RDPPF extract.
