1. Basics of Liquid Cooling. Liquid cooling is a technique that involves circulating a coolant, usually a mixture of water and glycol, through a system to dissipate heat generated during the operation of batteries.

The average temperature of the modified panel was reduced by 14.61 °C which enhanced the electrical efficiency by 6.8 %. The average power of the reference PV panel was found to be 10.87 W while for the modified panel this value reached 12.23 W. Wang et al. , utilized a solar desalination unit as a heat sink for the solar PV system.
Therefore, our design does utilize a method for storing energy for cooling as needed. The combined air conditioning and thermal storage system is intended as a technology to increase the effectiveness of solar photovoltaic energy use.
The back surface of the PV panel was cooled by capillary action through a cotton wick mesh installed on it. The mesh received water from a perforated pipe that was strategically installed on the upper side of the PV panel. Due to this placement water from the pipe holes also flowed on the front surface of the PV panel.
