Experimental system cools PV panels while keeping them clean

Researchers had placed a cotton sheet on the back of a PV module, which was then made wet and cooled. On the front side, water was pumped water from a pipe in a way that kept the panel both cool and clean. Their experimental setup showed superior results compared to reference cooling technologies. A group led by scientists from Egypt's Al-Azhar University has proposed a novel dual-use system for solar PV (SPV) panels, cooling them from both sides while also cleaning bird-dropping from the front side. Developing an experimental setup of the system, the group has also tested it under the conditions ...
