Developed a retractable photovoltaic roof that responds to weather changes
Two Swiss companies have jointly developed a smart solar roof that automatically folds in and out based on weather conditions.
According to engineers at Kronberg and SAK, their system reacts to light levels, so it expands when the sun comes out and starts to retreat when the sky is covered with clouds.

The partners installed a 4,000 m2 retractable roof in the spring over a parking lot for 150 cars near one of the local cable car stops. During the year, the array of 1,320 panels produces about 350 MW of power, powering 2 charging stations for electric vehicles.
The developers argue that automation increases the cost-effectiveness of photocells through proper control of the folding canopy.
Recall that recently a group of researchers have invented photocells that independently adapt to different levels of illumination.
