Germany may install 150,000 residential batteries this year

With the introduction of the reform of Germany's renewable energy law, or EEG 2021, the size limit that exempt owners of residential PV systems from paying the EEG levy, which finances all of Germany’s renewable energy incentives programs, was raised from 10 to 30 kW.

According to an analysis by German market research company EUPD Research, this is driving strong growth in the residential segment. In the first quarter of 2021, the addition of photovoltaic systems with an output of up to 10 kW increased by 39% compared to the same quarter of the previous year, with the newly installed capacity rising from 154 to 215 MW. As for the systems with an output between 10 and 30 kW, the growth was even steeper year-on-year at 142%, and the newly installed capacity increased from 27 to 66 MW:

EUPD Research expects this trend to continue in the further course of the year and assumes 1.5 GW of newly installed capacity for systems up to 10 kW. In 2020, a record total of 1.1 GW was recorded in this segment. For the photovoltaic systems with an output of between 10 and 30 kW, the analysts forecast a newly installed output of 600 MW this year.

This strong increase in rooftop PV systems up to 30 kW is also accompanied by growth in home storage systems. After an increase of 106,000 home storage systems in the past year, the analysts assume that 150,000 new battery storage systems will be installed this year. This is a growth of 42%. EUPD Research also expects a slight increase in the retrofitting of existing photovoltaic systems with home storage. They would make up around 15% of the total demand.

The increasing demand for PV home storage systems means, among other things, that battery providers are further expanding their capacities. In 2020, Sonnen and BYD were the leading suppliers with a market share of 20% and 18%, respectively, as EUPD Research determined through extensive inquiries from manufacturers, installers, and end customers. E3/DC and Senec are in third place with 17% each. Overall, the leading manufacturers supplied 72% of all newly installed photovoltaic home storage systems.
