Overview
- The BSW reported in August 2026 that installed photovoltaic capacity in Germany has topped about 128 gigawatt‑peak, meeting the legally set 2026 expansion target.
- The association warned that draft laws for the Renewable Energy Act and the grid‑connection package would reduce support for small PV, tighten direct‑marketing rules, and lower curtailment compensation, which it says could deter investors and cause an 'Ausbauknick'.
- Germany still needs roughly 87 GWp more to reach the 215 GWp 2030 goal, which implies average new installations of about 20 GWp per year compared with roughly 17.5 GWp added in 2024 and 2025.
- Consumer demand for plug‑and‑play 'Balkonkraftwerke' and bundled PV+storage sets is rising sharply, driven by falling prices, modular offers, and regional subsidies that can cut payback times to a few years in many cases.
- Independent field tests and reviews show wide variation in real‑world yields and amortisation: small 960 Wp systems produced about 637 kWh and pay back in roughly 4.8 years in one test, while 2 kW sets with storage returned higher annual yields and payback windows from about 2 to 7 years depending on price and configuration.
