Researchers at Ben-Gurion University of the Negev have explored an unconventional method to enhance solar panel efficiency: submerging them in shallow water. The study, conducted by master's students under the academic supervision of Dr. Vitaly Gitis and Meirav Pins Summer, found that this cooling technique could potentially increase electricity generation by approximately 15%. Solar panels' efficiency decreases as they heat up from sunlight, a challenge particularly acute in hot climates like Israel's. For every degree Celsius above 25°C, panel output can drop by about 0.5%, primarily affecting the electrical voltage produced. This cooling method leverages water's high specific heat capacity to absorb heat and maintain a lower operating temperature for the solar cells. The inspiration for this project came from a visit to the startup Carrar, which developed a liquid immersion cooling system for electric vehicle batteries. While the water submersion method is still in the research phase and faces questions regarding economic feasibility and water consumption, it represents a promising avenue for active cooling. Students Ron Bleila and Or Avixis, who led the project, believe future advancements will likely involve a combination of technologies, including advanced optical coatings and AI-driven thermal management systems, to optimize panel performance in varying weather conditions. Pins Summer noted that Israel possesses both the need and the technological capabilities for such innovations.
