The Swiss market for battery storage is growing rapidly
In Switzerland, around 555 new battery storage systems were installed in 2025. This brings the total number of storage systems connected to the grid to 1,451. This is according to Swissolar’s Battery Monitor 2026. The association expects this figure to rise to 2,461 installed systems by 2026.
The roll-out of battery storage systems is accelerating. This is according to Swissolar’s Battery Monitor 2026. According to the report, 896 storage systems were installed in Switzerland by the end of 2024. The Swiss Solar Energy Association expects a further 555 storage systems to have been connected to the grid in 2025. This means that by the end of 2025, there are likely to have been 1,451 storage systems connected to the grid.
For the current year, Swissolar even expects the number of new installations to double to 1,010. This would bring the total number of installed storage systems to 2,461.
Currently, storage capacity is increasing particularly behind the grid connection point, i.e. in households and in agricultural and commercial enterprises. This is expected to rise to 2.5 gigawatt-hours by the end of 2026. At the end of 2025, the figure stood at just 1.5 gigawatt-hours.
The expansion of battery storage within the electricity grid is also increasing. Companies have already announced an expansion of over 4 gigawatt-hours by 2030.
Matthias Egli highlights the significance of this for the energy transition. “Battery storage makes an important contribution to an electricity system with a high proportion of renewable energy,” the Managing Director of Swissolar is quoted as saying in the press release on the Battery Monitor. “It helps to use solar power efficiently, relieve the strain on the electricity grids and reduce overall costs.”
