Overview

• More than one million plug-and-play balkonkraftwerke are officially registered in Germany, with over 200,000 new systems added in the first half of 2025.
• The IEC-Norm 60364-7-751 draft would restrict connections to specially protected circuits and require certified electricians for installation.
• The Bundesverband Steckersolar e. V. and leading PV providers have mounted a coordinated push to preserve the existing Schuko-plug simplicity.
• Retailers and startups such as Solakon, solago, Kleines Kraftwerk, Powerness, Solarway and Maxxisun are rolling out discounted PV-and-storage bundles to meet rising homeowner demand.
• Households are increasingly equipping balkonkraftwerke with 1–3 kWh modular batteries or scalable solutions like Maxxicharge V2 to store excess solar power and boost self-consumption.
