Overview
- Germany’s registered plug-in mini-PV systems have surged to nearly 870,000 units in early 2025, with expectations to surpass 1 million by mid-year.
- The 2024 SolarPaket 1 reform, which raised inverter and module capacity limits, continues to facilitate widespread adoption of balcony solar systems.
- Retailers like Netto, Solarway, and Solakon are offering steep discounts on storage-integrated systems, with entry-level kits starting under €240.
- Battery storage options range from basic 2 kWh units to expandable systems up to 16 kWh, with prices as low as €197 per kWh for some models.
- Despite advances in storage, mini-PV systems typically meet 25–90% of household electricity needs, with full energy independence requiring costly seasonal storage solutions.
