The DEF Solar self-contained flat roof window is powered by solar energy using a special photovoltaic panel. The product therefore does not need to be connected to the building's electrical system.
The photovoltaic panel integrated into the battery allows it to operate even in cloudy weather. The proven construction guarantees excellent performance and impeccable aesthetics. Convenient use with the Z-Wave wireless system using the remote control.
The frame of windows for flat roofs is made of multi-chamber PVC profiles. They are filled with a heat-insulating material. The upper part of the window is an innovative flat glazing.
