Overview

• Germany has registered nearly one million plug-and-play PV systems under the 800 W inverter and 2 000 W module limits as of July 2025.
• Under VDE standards, each inverter must connect to a separate circuit but installations within the 800 W cap can be self-installed without a certified electrician.
• Bundesnetzagentur’s MaStR filings remain straightforward and ongoing VAT exemptions through 2025 boost affordability for urban households.
• Vendors are rolling out ultralight flexible modules and AI-driven battery banks with capacities up to 16 kWh, backed by aggressive Prime Day and summer discounts.
• Independent trials report self-consumption rates above 80% and average savings of around €160 per year, with full cost recovery often in three to seven years.
