Egyptian researchers have created innovative solar panels that clean themselves. The design is inspired by nature, specifically how tree leaves shed dust. In regions with a lot of dust, traditional solar panels often lose efficiency due to dirt buildup. The self-cleaning technology uses mechanical vibrations to shake off dust.
The system operates twice a day, significantly reducing the cost and frequency of manual cleaning. This approach allows solar energy systems to maintain their efficiency with less maintenance. While trials show that these panels are performing well, the overall economic viability compared to regular cleaning is still being assessed.
Additionally, researchers have developed a wind-driven version. This uses air movement to clean the panels naturally, offering further promise for sustainable energy solutions in desert conditions.
