Overview of Recent Solar Photovoltaic Cooling System Approach
Today, one of the primary challenges for photovoltaic (PV) systems is overheating caused by intense solar radiation and elevated ambient temperatures [1,2,3,4].To prevent immediate declines in efficiency and long-term harm, it is essential to utilize efficient cooling techniques [].Each degree of cooling of a silicon solar cell can increase its power
New solar panels suck water from air to cool themselves down
In a desert environment with 35% humidity, a 1-square-meter solar panel required 1 kilogram of gel to cool it, whereas a muggy area with 80% humidity required only 0.3 kilograms of gel per square meter of panel. The upshot in either case: The temperature of the water-cooled solar panel dropped by as much as 10°C.

Enhancing Solar Photovoltaic System Efficiency: Recent Progress
There is a paradox involved in the operation of photovoltaic (PV) systems; although sunlight is critical for PV systems to produce electricity, it also elevates the operating temperature of the panels. This excess heat reduces both the lifespan and efficiency of the system. The temperature rise of the PV system can be curbed by the implementation of
A review on solar-powered cooling and air-conditioning systems
The PV panel generates direct current (DC), which requires an inverter to run the traditional AC compressor (DC compressors also can be used to eliminate the inverter).
