Overview

• Germany has installed approximately 107.5 GW of photovoltaic capacity, hitting half of its 2030 expansion goal.
• Over one million balkonkraftwerke now feed about 13.8% of national electricity consumption.
• Solar oversupply resulted in nearly 390 hours of negative wholesale prices in the first half of 2025.
• With only around 20 GWh of battery storage online versus a 100–150 GWh need, the Stiftung für Klimaneutralität ten-point plan aims to reorient subsidies and lower the direct-marketing obligation to 2 kW by 2030.
• Market providers like Solarway and Enpal are cutting PV-and-storage bundle prices to help absorb surpluses and support self-consumption.
