• Germany is on track to register almost one million mini-PV balcony systems, up from 780,000 in Q3 2024 following Solarpaket 1 reforms.
• A 2025 VAT exemption and simplified 800 W cap rules have cut acquisition costs by 19% and eased homeowners’ administrative burdens.
• Battery storage has become a standard feature in plug-and-play kits, offering modular expansion and AI-driven management to boost self-use of solar power.
• Major retailers are promoting aggressive deals on kits, such as Solakon’s 900 W onLite system for under €200 with potential annual savings of €300 and Powerness’s Anker Solarbank 2 Pro sale at €679 using “Anker250off.”
• EcoFlow’s STREAM Ultra hybrid unit connects directly to appliances at up to 2,300 W, starts at €899 for 1.92 kWh capacity and scales to 12 kWh, sidestepping the 800 W grid-feed limit.
