In brief: Ein Solar-Rollladenmotor ist ein Rohrmotor mit eingebautem Akku, den ein kleines Solarpanel am Fenster lädt. Es muss kein Kabel verlegt werden – ideal für die Nachrüstung im Bestand und für Fenster ohne Steckdose in der Nähe. Gesteuert wird per Funk.
How it works
- The solar panel is mounted outside, e.g. on the shutter box, and charges the battery.
- The motor runs on 12 V from the battery.
- Operation via radio hand transmitter; the Zigbee version also via app and voice control.

When is solar worth it?
Solar is worth it if there is no power connection at the window and laying one would be expensive or unsightly – e.g. in old buildings, rented flats or with roof window shutters. If there is power at the window anyway, a 230 V motor such as the AM45 mechanical (from €65) or the AM45 radio (from €100) is cheaper.
Limits
- The panel needs daylight; on the north side it charges more slowly.
- 20 Nm is not enough for very heavy roller shutters or roller doors – a 230 V motor is then required.
Frequently asked questions
Does an electrician need to connect the solar motor?
No, there is no mains connection. Motor and panel are only installed mechanically and connected to each other.
What happens when the battery is empty?
The roller shutter stops until the panel has recharged the battery.
