Overview
- Multiple vendors offered deep discounts on Monday, July 27, pushing 900–1,000 W starter kits into roughly €189–€319 and Solakon’s 1,000 W onBasic down to €239.99.
- German rules draw a clear line for plug‑and‑play 'balkonkraftwerk' status: up to 2,000 Wp total module capacity and a maximum of 800 W inverter feed‑in require only registration in the Marktstammdatenregister.
- Systems that exceed those thresholds remain legal but are reclassified as regular PV installations and typically need network‑operator notification, electrician installation or a bidirectional modern meter.
- Vendors are bundling modular batteries and smart meters—storage units from about 2 kWh up to 12+ kWh raise self‑consumption, shorten payback in many cases and enable evening or backup use.
- Analysts warn a policy shift in China from April 2026 plus rising commodity costs could push module prices up by as much as about 20 percent, which would narrow the current low‑price window and may lengthen battery delivery times.
