Overview
- Retailers rolled out steep Black Month price cuts that bundle high‑efficiency bifacial modules with Anker SOLIX batteries, for example Solago's 2,000 W kit with a 5 kWh SOLIX 4 Pro for €1,849 and other vendors offering deeply discounted 900–2,000 W sets.
- Sellers are simultaneously marketing much larger multi‑module offers, including a 6,000 Wp Solarhandel24 package, which exceeds Steckersolargerät limits and therefore must be treated as a regular PV installation with electrician work and registration.
- Expandable LiFePO4 storages, notably Anker's SOLIX family, are central to current offers because tests rate them highly and field data show storage doubles usable self‑consumption; home&smart gave the SOLIX 4 Pro top scores and a six‑month 1.6 kW + ~4 kWh field test recorded 635 kWh with 89% used on site.
- Economics remain strong for buyers: multiple analyses and tests point to typical payback in roughly three to five years when systems include storage, but real yields depend on orientation, seasonality, storage efficiency and the 800 VA AC limit that distinguishes plug‑in devices from full installations.
- The German model is driving rules abroad as registries show a large domestic market—1.53 million devices totaling 1.67 GW reported to the Bundesnetzagentur—and jurisdictions from the UK to several U.S. states and Western Australia are adopting or adapting German product norms.
