German manufacturer of facade systems Ehret has introduced SolarSlide, a sliding shutter with integrated PV modules designed for building facades. The system was developed with Fraunhofer ISE and has been available in France since January.
The device combines sun protection with on-site power generation. Each glass-on-glass module measures 1,000 mm by 1,000 mm and contains 25 monocrystalline cells with a power of approximately 141.7 W. The shutter, installed as a sliding panel for windows, filters direct sunlight to reduce heat gain in summer while retaining daylight.
Ehret offers two configurations. The SolarSlide version is designed for medium-sized installations and can be connected to external inverters and energy storage systems. SolarSlide Pro contains an integrated microinverter and can be connected directly to a standard 230 V socket, aimed at smaller residential or renovation projects.
The modules feature a colored glass-on-glass construction without visible cell structures, allowing architects to integrate them into new or renovated facades. The track-mounted sliding system is based on Ehret’s aluminum joinery designs and supports large window openings.
The product targets the building-integrated photovoltaic solar energy (BIPV) market, where facade elements such as sun blinds are increasingly used to generate electricity while improving the energy performance of buildings.
