ROLLER SHUTTERS GO OFF THE GRID THANKS TO SOLAR ENERGY
Bubendorff, based in France’s Alsace region, launched a revolutionary new roller shutter, the ID2 Autonome, in 2012. The 100%-solar-powered shutter runs off a small PV solar panel and requires no backup power source.
Technology
All of the shutter’s components were designed for optimal energy consumption and lifespan—backed by the manufacturer’s seven-year guarantee. Leti worked with CEA renewable energy lab Liten on the following product development issues:
- Selecting a high-performance battery
- Managing battery charging and discharging
- Improving the energy efficiency of shutter opening/closing
- Reducing standby energy consumption
- Improving the energy efficiency of the radio control system
Energy consumption for the radio control system was slashed by a factor of 100 as compared to previous-generation radio communication systems. The overall product is so energy-efficient that it can operate with no backup power even when installed on the north side of a building.
