Germany will continue to dominate the European home battery market – no matter who is in government – pv magazine International

Industry association SolarPower Europe expects little change in the lineup of Europe’s largest residential battery markets in four years, with a rush of renovations as turn-of-the-century solar power prices start to rise. expire, which should keep Germany far ahead of the pack.

While the photovoltaic trade body SolarPower Europe is optimistic about the prospects for home energy storage, the second edition of its Outlook for the European Residential Battery Storage Market The market is hardly expected to diversify far beyond the current five big countries, dominated by Germany.

With Germany accounting for 70% of domestic batteries installed in Europe last year and the five largest markets – also including Italy, UK, Austria and Switzerland – capturing 93%, SolarPower Europe is expects France to supplant the latter in an otherwise identical line. -until 2025.

Net metering programs that encourage home solar power owners to export excess electricity to the grid, rather than storing it in a residential battery, will continue to hamper growth in the Netherlands and Belgium, although both EU Member States are slowly moving away from such systems. The picture is even bleaker in Eastern Europe, according to the report – released yesterday – with cheap electricity, often powered by fossil fuels, coupled with a lack of political support.

Get the latest edition of pv magazine to discover the many software solutions serving the energy transition. From big data and artificial intelligence removing the hard work of operations and surveillance, to moving towards international standards and consensus to ensure that power grids are protected from cyber attacks and other digital threats; the bits and bytes of software solutions play a complex and central role in the energy system.

The important role that policymakers can play in driving sales was spelled out by a blunt statement in the report that referred to the ongoing negotiations in Germany to form a new coalition government. The study posing low, medium and high scenarios through 2025, the authors wrote: “A new German coalition government without conservatives is likely to push developments towards [our] high scenario. The same would also be true if the Green Party were part of the new cabinet, the report added later.

Describing Germany as “the European powerhouse in both residential solar PV systems and residential battery storage systems,” the document says the country added 749 MWh of household batteries last year, to represent the lion’s share of the 1,072 MWh installed on the European domestic battery market. passed the gigawatt mark of annual installations for the first time.

This is perhaps not surprising given that the highest quality solar and home storage systems in Germany can offer a discounted energy cost of just € 0.122 / kWh, or about a third of the price. typical retail electricity in what is expensive energy. Marlet. This saving ensures that around 60% of new residential solar systems installed in Germany today are accompanied by batteries.


SolarPower Europe plans an increase in modernized batteries to strengthen the market from this year, as the first solar panel to benefit from the 20-year feed-in tariffs introduced by the Erneuerbare-Energien-Gesetz (EEG) Renewable Energy Act in 2000 begin to expire.

The report’s average expectation (neither Greens nor Tories in government, perhaps?) Estimates that Germany will add 1,181 MWh of household batteries next year, followed by annual yields of 1,402 MWh, 1,577 MWh and 1 793 MWh for 5.95 GWh of battery capacity installed between this year and 2025.

The approximately 90,000 battery systems added in Italy last year have enabled Europe’s second-largest home storage market to add 94 MWh of capacity, far behind Germany, but reinforced by the extension, until 2023, of the “super bonus” incentive to recover Covid which offers a tax reduction of 110% of the value of residential solar and storage systems provided they are suitable for more substantial renovations of the energy efficiency of buildings. Italy is expected to add 625 MWh of new battery capacity between this year and 2025, according to the study’s authors.

While SolarPower Europe is ready to offer advice to politicians who are trafficking for Bundestag influence right now, it was also ready to offer thoughts on the UK – Europe’s third largest home storage market – with the professional organization lamenting that “political uncertainty remains high in the UK these days”, thanks to Brexit.

Around 11,000 residential batteries were installed in the UK last year, according to the report, despite the lack of feed-in tariffs for solar power, but the ability of energy users to maximize battery yields is crippled through the poor deployment of smart meters. The ongoing devastation among new energy companies in the country, thanks to soaring gas prices right now, could be another hurdle and the section of the SolarPower Europe report praising the ‘high level of liberalization’ in the UK market. energy already looks stale as fears grow that only the ‘Big Six’ will survive, after Bulb – the country’s seventh largest energy company – disappears this week.

Still, the document predicts the UK will install 500 MWh of batteries from 2021 to 25.


Austria, which could introduce a new solar and storage subsidy by the end of the year, added around 6,000 residential batteries last year, for a total storage capacity of around 41 MWh, and is expected to add 304 MWh for the 2021-25 period.

The only change in the top five European markets expected by SolarPower Europe in 2025 is France’s overhaul in Switzerland, with homeowners warming up to technology despite low electricity prices in the former country which are largely due to its large nuclear fleet. A supportive policy will see France add 178 MWh of domestic storage capacity over the 2021-25 period but, SolarPower Europe added, Switzerland will remain a promising market and there is also potential in Spain, Ireland and the Czech Republic. .


With the trading body predicting that the EU will need 1.6 TWh of small-scale ‘distributed’ energy storage by mid-century to achieve a net zero economy, SolarPower Europe has called on lawmakers working on a current European regulations on batteries to take into account the carbon of the device. footprints and recycled content, as well as “due diligence,” which may relate to the rights of workers in the supply chain.

In an interesting aside for the solar industry in the report – which will be updated annually – the trade body said it expects the current rise in prices for solar panels and batteries to be a hit. temporary on a long-term downward trend in prices “as supply chains adapt” to post-Covid shocks. The situation will improve from the second half of next year, according to SolarPower Europe.
