Overview

• Germany's plug-in balcony solar installations have surpassed 870,000 units by April 2025, reflecting continued growth driven by regulatory support and consumer demand.
• The SolarPaket 1 reform, which raised feed-in limits to 800 watts, has facilitated the integration of battery storage systems into balcony solar setups.
• New battery storage products, such as the Growatt NEXA 2000 with four MPPT inputs and the APSystems EZHI expandable to 40 kWh, are enhancing energy efficiency and self-consumption.
• Retailers are offering aggressive discounts on storage systems, with entry-level prices starting below €500, making them more accessible to households.
• Battery storage adoption is supported by falling prices, payback periods of three to ten years, and incentives like rising electricity costs and local subsidies.
