This project is about the cooling of solar panels with hydrogel in the Sahara desert. It is already known that solar panels lose a significant fraction of their efficiency when they are exposed to high temperatures. This project did research in the effectiveness of cooling solar panels with two types of hydrogel, Potassium Polyacrylate and with Sodium Polyacrylate. This project contains results of self performed experiments with these hydrogels on the top and on the bottom of a monocrystalline solar panel. Besides the practical testing with hydrogel, this project also theoretically covered some hydrogels, for example PAM-CNT-CaCl2. The overall aim of this project was to find a new, safe and economically profitable way to cool solar panels.
