Technical FAQs 4

Why do people store solar power in Germany?

To date, most battery storage systems in the German electricity system have been used exclusively to optimize self-consumption. Consequently, an exponentially growing number of homeowners and companies store solar power for times when solar generation is low.

How many battery storage systems were installed in Germany in 2024?

Almost 600,000 new stationary battery storage systems were installed across Germany in 2024, increasing the country’s storage capacity by 50 percent year-on-year, according to preliminary data from the German Solar Industry Association (BSW Solar).

What is the future of solar power in Germany?

Sustained growth is forecasted in the market for new PV capacity for years to come. Concurrently, battery systems are expected to reach a capacity of at least 100 GWh by 2030, reflecting a transformative shift within the German energy system towards renewable energy integration.

What if a battery storage project was approved in Germany?

If only half of these projects were approved, they would store enough energy to power 30 million German households for one day. Battery storage is needed to supplement the country’s rapid rollout of renewable energy installations, which reached a new record share in electricity production of 55 percent in 2024.
