Overview
- Retailers rolled out weekend deals Saturday, with four‑panel 2,000 W sets plus 2.68 kWh batteries priced around €1,217–€1,399 and entry plug‑and‑play kits advertised under €200.
- Add‑on batteries raise self‑consumption and can keep small loads like phones, routers and lights running for hours, though typical 1–4 kWh units are not sized for ovens or electric heating.
- By rule and design, micro‑inverters shut down in a power cut because they need the grid’s 50 Hz signal for reference, so only storage units with certified UPS emergency power keep devices on.
- Local data underscores real savings, with Stadtwerke Pirmasens reporting about €231 a year from its demo system and 99 kWh produced in January–March 2026 worth roughly €31 at retail rates.
- Vendors push bifacial and TopCon panels, LFP batteries and AI energy tools, and current practice pairs up to 2,000 Wp of modules with an ~800 W feed‑in cap plus smart meters to enable zero export to the grid.
