Subsidies for battery storage in Switzerland 2026

No. There is no uniform federal subsidy for private battery storage in 2026. The national subsidy through Pronovo covers photovoltaic systems, not the battery storage as a separate device. However, additional contributions may be available depending on the canton, municipality or energy supplier.

No, Pronovo subsidises the photovoltaic system, not the battery storage. Those who install a PV system with storage can check for a one-off payment for the solar system. However, the storage unit itself does not automatically receive its own subsidy as a result.

In 2026, Schaffhausen and Thurgau are particularly relevant. In other cantons, municipal programmes, contributions from energy suppliers or special programmes may exist. Therefore, the subsidy should always be checked based on the specific address or postcode.

For many cantonal or municipal subsidy programs, the application must be submitted before ordering or the start of installation. If the battery storage is already installed before the subsidy approval is received, the right to the subsidy may be lost. The exact deadline depends on the respective program.

This depends on the subsidy programme. Some programmes support storage in combination with existing or planned photovoltaic systems. Other programmes only subsidise new installations or exclude extensions. Therefore, before ordering, it should be checked whether the existing PV system meets the conditions.

A separate subsidy solely for backup power functions is generally not provided. Individual programmes subsidise battery storage as stationary storage for a grid-connected PV system. Whether the storage can also provide backup or emergency power is a technical question and must be separately specified in the quote.

Yes, a battery storage system can be worthwhile even without a subsidy if it significantly increases self-consumption and matches your consumption profile. Key factors are the electricity price, feed-in tariff paid by the grid operator, storage costs, usable capacity, lifespan, and consumption in the evening or at night. A subsidy improves economic viability but does not replace sound planning.

For many single-family homes, the appropriate battery storage size is roughly in the range of 5 to 15 kWh of usable capacity. However, this is only a guide. The decisive factors are the size of the PV system, electricity consumption, the daily distribution of consumption, a possible heat pump, an electric car and the desired backup power function.

Not necessarily. Some subsidy programmes work with minimum sizes, maximum contributions or percentage limits. An oversized battery storage system can be uneconomical despite subsidies if its capacity is barely used in everyday operation. The storage size should therefore be chosen based on actual demand rather than the maximum subsidy available.

Often, a combination is possible because the photovoltaic system can be subsidised via Pronovo and the storage via a cantonal, municipal or local programme. However, the specific cumulation rules vary depending on the funding body. Subsidies should therefore be reviewed together before placing an order.

Depending on the location and project, battery storage can be interesting for apartment buildings, ZEV, virtual ZEV or local electricity communities. However, a subsidy is not guaranteed. In addition, the metering concept, billing, ownership, operation and cost distribution must be clearly regulated.

For commercial businesses, battery storage can be interesting if it increases self-consumption, reduces peak loads or makes better use of variable tariffs. However, subsidy programmes depend on the location and project. For commercial systems, economic viability should be calculated using actual load profile data.

The subsidy should be checked based on the address. The canton, municipality, local energy supplier and current subsidy databases such as Energiefranken are relevant. It is also worth taking a look at the conditions of the cantonal energy subsidy programme.

Economic viability is more important. A subsidy can improve the investment, but a poorly sized battery storage often remains unattractive even with a grant. What matters is that the battery size, consumption, photovoltaic system, inverter, tariff model and desired features all fit together.
