Overview
- Coverage Friday and Saturday showed discounters and specialist retailers offering turnkey 2,000 W Quattro packages with integrated batteries for about €1,300–€1,400 and standalone storage units deeply discounted to under €600.
- Those Quattro packages pair four 500 W bifacial panels with multi‑MPPT inputs and a smart meter to maximize self‑consumption and to keep the grid feed‑in below the legal 800 W inverter limit.
- Experts and buyer guides say systems with storage materially raise evening use of self‑generated power, shortening amortisation to roughly 2–5 years and saving households a few hundred euros a year depending on size and use.
- Some vendors are selling 4,000 W module bundles at similar promo prices but regulators and testers warn such larger arrays can trigger full rooftop‑PV rules, extra registration and installation obligations.
- The market surge builds on the May 2024 Solarpaket 1 changes and broad vendor competition this summer, though analysts caution prices could rise later in 2026 if export incentives and raw‑material costs change.
