UAE Scientists Cool Solar Panels With Mist
19 Oct
Summary
- Mist-cooled panels produced 26.05% more energy than standard panels.
- Heat significantly reduces solar panel efficiency and power output.
- New design tackles water and scaling challenges for wider adoption.
Solar panels lose efficiency as they heat up, a significant issue in hot climates like the UAE. Researchers from United Arab Emirates University and the University of Sharjah have engineered a novel "mist-cooled sandwich bifacial panel." This design places two solar panels back-to-back with a fine water mist sprayed between them.
In outdoor tests conducted in July 2025, this innovative setup generated 26.05% more energy than conventional single-sided panels. The mist effectively cools the panels, mitigating the power loss typically associated with high temperatures. This advancement offers a promising solution for maximizing solar energy yield in regions facing intense heat.
While the system shows great potential, challenges remain. The significant water usage in arid environments requires further refinement. Researchers are working to reduce water and energy consumption and are exploring the use of second-life solar panels. The patented technique's commercial viability hinges on managing the costs associated with pumps, nozzles, and water against the projected energy gains.
