Overview
- Major online sellers and discounters ran overlapping clearance-style deals this week, and on Wednesday several outlets listed complete 2.0–4.0 kWp PV plus battery kits for about €1,199–€1,369.
- Anker’s launch of the SOLIX 4 — a roughly 5 kWh base LiFePO4 storage unit with up to 5,000 W PV input and four MPPTs — has pushed prices of the smaller SOLIX 3 (≈2.7 kWh, expandable) sharply down and sparked bundle discounts.
- Technical trade-offs matter: larger module arrays (4 kWp or eight 500 W panels) substantially raise annual yield, improve morning and evening generation, and shorten payback compared with 2 kWp sets charged to the same small battery.
- Retailers and reviews commonly model amortisation in roughly three to six years, but actual payback depends on local irradiation, household evening consumption, chosen storage size, and whether installation or qualified electrical work is included.
- Buyers should note regulatory and installation limits because systems over 2,000 Wp or non‑plug configurations can require registration, notification to the grid operator, or qualified installation, and some advertised prices exclude mounting or electrician costs.
