Overview
- Retailers push season-low pricing: Solarway lists 2,000 W sets with either Anker SOLIX 3 (2.7 kWh) or EcoFlow STREAM Ultra X (3.84 kWh) at €1,499, PluginEnergy offers a JA Solar + SOLIX 3 bundle at €1,439, Solakon advertises €899.99 with a 2.11 kWh storage option or €399.99 without, and Kleines Kraftwerk promotes a 1,000 W kit for €299.
- Most bundles pair four 500 W bifacial modules with modular LiFePO4 storage; tested units include Anker SOLIX 3 (95/100 in April 2025, expandable to ~16 kWh) and EcoFlow STREAM Ultra X (93/100 in August 2025, expandable to ~23 kWh).
- Savings estimates cited range from roughly €430–500 per year for a 2 kWp + 2.7 kWh setup and about €500–580 for 3.84 kWh, with reported payback periods of around 2.5–3.5 years depending on configuration and usage.
- German rules highlighted in coverage note 2,000 Wp module power with current 600 W feed-in limits, a prospective move to 800 W pending standardization, and ongoing obligations to register in the Marktstammdatenregister and notify the grid operator.
- Experts caution that very cheap sets may cut corners on inverters or mounts and advise checking CE/norm compliance, warranties and specialist support; local subsidies, such as Berlin’s €250 grant, can further reduce net cost.
