Wind-driven technical forces Solar panel Dust remove without external electricity
Due to a joint effort with Dr. Wanchul Seung At the Global Technology Research Division of Samsung Electronics, Professor Juhyuck Lee and his team of the Department of Energy Science and Engineering at Dgist have developed a self -intended system for cleaning solar panels. The innovation combines wind energy with the technology for electrodynamic screen (EDS), which eliminates the need for external power sources.
Dust structure on solar panels can drastically reduce their efficiency. EDS Technology, which uses electric fields to release dust, has proven to be valuable at external locations such as deserts and mountainous areas where manual cleaning is impractical. However, traditional EDS systems require high voltage and external energy, which increases maintenance costs.
In 2024, DGIST researchers proposed a wind-driven, one-phase EDS solution, but suffering from limited performance. Its effectiveness was highly dependent on the increasing angle of the panel, because dust removal was dependent on gravity-based, side-side movement.
To overcome these shortcomings, the DGIST team introduced a three-phase EDS system powered by a wind-driven rotation triboelectric nanogenenerator (Teng). This new setup uses specially designed three -phase electrodes to actively steer dust from the panel surface, functioning efficiently, regardless of orientation.
Tests showed the system that was generated up to 1,383 volts and achieved 83.48% efficiency of dust removal 1.6 times higher than previous designs. When wind is only driven, the technology restored the performance of solar panels to around 96% of their original power conversion -efficiency.
“The most important collection meal in this study is that three -phase high voltage generated by wind energy is used to move dust in the desired direction, and it does not require external power,” said Professor Lee. “This technology will reduce the maintenance costs of solar panels and can be used efficiently in a wide range of environments.”
The research was supported by the Korean Ministry of Science and ICT and the National Research Foundation, with findings published in Nano Energy. First authors were Dgist -grader students Cheoljae Lee and Junyoung Yang.
