SOLAR PANELS THAT FOLD THEMSELVES BEFORE THE STORM Researchers at Graz University of Technology have developed FLAPTrack, a dual-axis photovoltaic system that follows the sun while automatically folding into a protected position when hail, strong winds or snow threaten. A patented linear actuator performs two functions: adjusting the panels’ vertical angle and folding their front surfaces together. A belt-driven circular guide rotates the system horizontally. When severe weather approaches, the array closes face-to-face and lies near the ground, reducing wind exposure while shielding the photovoltaic surfaces. An inexpensive hail net can protect the exposed rear sides. A 1.8-kilowatt-peak prototype operating on TU Graz’s Inffeldgasse campus produced nearly 40% more electricity on average than fixed panels, with individual days reaching 56%. During mornings and evenings, it generated more than twice the conventional output because it remained aligned with the low sun. That timing could be commercially important. Electricity demand frequently rises during those periods, while conventional solar output declines. The system may offer additional advantages in winter and at higher latitudes by shedding snow and reducing dust accumulation. Key Takeaways: FLAPTrack combines energy optimization and weather protection within the same mechanical system. The university’s prototype results are promising, but they do not yet establish lifetime economics or performance across different climates. Implications: Commercial success will depend on whether additional electricity and avoided storm damage outweigh installation, maintenance, motor power and component-replacement costs. Long-term testing of wear, wind forces and autonomous forecasting will determine whether this becomes a resilient infrastructure solution or remains a specialized tracker.
