The market for home storage is growing at a record pace across Europe. For example, in its latest market study for residential energy storage, SolarPower Europe calculates an increase in storage capacity of 71% (3.9 GWh) in the most likely scenario for the past year.
This corresponds to more than 420,000 new storage batteries and a total installed capacity of 9.3 GWh. By the end of 2026, the European industry association even expects total storage capacity to increase by 300% to 32.2 GWh, equivalent to 3.9 million European households optimizing the self-sufficiency of their power supply and limiting their electricity costs.
In the European country ranking of residential storage markets, Germany once again held the undisputed top position in 2021 with a market share of 59%. In a forecast up to 2026, SolarPower Europe expects Germany to remain the undisputed market leader in home storage during this period.
The top position of the German storage market essentially results from the fact that the demand for systems for domestic and commercial solar power generation is driven by the exploding electricity costs and, at the same time, 70 % of newly installed photovoltaic systems are built in combination with a storage battery.
Thanks to the extremely successful "Superbonus 110" subsidy program, Italy was able to secure second place among European storage nations in 2021 with a market share of 14 %. Austria is in third place with 6%. The UK has dropped one place to 4th place, also with 6%. Switzerland is in fifth place with 3%.
Together, these five countries cover 88% of the European residential storage market. However, all the other markets considered also grew by an impressive 137 % on average. The strongest growth in this group is shown by Poland and Sweden, which could take 3rd and 4th place in Europe by 2026.
