Germany: 2019 a record year for residential energy storage installations

According to a study by market research firm EUPD Research, by the end of 2019, there were about 206,000 energy storage systems in homes throughout Germany.

About 65,000 new residential battery solutions were installed in 2019 an increase of 44% over the previous year. On the solar side, about 78,500 new residential solar systems, ranging in size from 3 to 10-kW, were installed in 2019, an increase of 41% over 2018.

Dr Martin Ammon, COO of EUPD Research explained that the average size of a residential energy storage system in Germany is about 4kW, so the country installed about 260MW of total capacity in 2019. Further, the total installed capacity of residential energy storage in the country is about 700MW.

For comparison, the Energy Storage Association in the U.S. said in its annual report that the residential energy storage market experienced at 66% growth rate in 2019 with total installed energy storage capacity around 272 MW of behind-the-meter (BTM) installations. That number, however, includes all BTM deployments, which means businesses and residential energy storage.

EUPD research said that falling costs for both PV and battery storage alongside rising electricity prices in Germany are driving that trend to self consumption on PV plus storage. Further, the increasing number of electric vehicles may also be driving the uptick in PV installations, according to EUPD Research.

The study shows that the cumulated energy storage market volume doubled within the last two years with currently about 206,000 residential storage systems installed in Germany.

“The photovoltaic success story appears to repeat itself for residential energy storage in Germany. Besides challenges presented against the background of the coronavirus pandemic, the residential energy storage market in 2020 is confronted with market limitations caused by a 52GW solar cap,” said Markus A.W. Hoehner, CEO EUPD Research. 

Battery manufacturers sonnen and BYD are top suppliers

Despite a growing number of suppliers in the market, the top positions have been dominated by the same providers over the last few years, said EUPD Research. Front runner sonnen from Bavaria is followed by Chinese manufacturer BYD. E3/DC, based in Osnabrück, and manufacturer SENEC from Leipzig, Saxony, are in third place with a market share of 14 percent respectively. The Korean manufacturer LG Chem completes the top 5.

Market share calculations for residential storage in Germany are based on a number of comprehensive surveys of manufacturers, solar PV installers and residential end consumers, complemented by further in-house research data. It is assumed that suppliers with a primarily two-step distribution have about 10% of their products either stored in warehouses or still in the sales process, while suppliers with a more three-step distribution are assumed to have 15% of storage products that have not been installed yet.
