In brief: A roller shutter motor draws a few hundred watts while running but only runs for seconds a day. Consumption for the runs is therefore usually below 1 kWh per year. Radio motors add the standby consumption of the receiver.
Calculation example
| Item | Assumption |
|---|---|
| Performance | 150 W (use the value from the rating plate) |
| Running time | 20 seconds per run, 2 runs per day |
| Runs per year | 150 W × 40 s × 365 ≈ 0.6 kWh |
| Standby radio motor | Assumption 0.5 W × 8760 h ≈ 4.4 kWh |
The values are examples. The exact power is on the rating plate or in the data sheet; the standby value depends on the receiver.
Without mains power: battery-solar
A A-OK AM45 battery-solar charges its battery via a small solar panel and needs no mains connection. More: Solar roller shutter motor.
Does an electric roller shutter save energy?
Closed roller shutters reduce heat loss at the window at night and keep heat out in summer. With timer control this happens regularly – even when nobody is home, see Automatic roller shutter control.
Frequently asked questions
Does a mechanical motor use electricity when idle?
A cable motor without electronics draws no current when idle, as long as the switch is not pressed.
How high are the electricity costs?
With a few kWh per year, usually only one or two euros per motor – depending on the electricity price.
