Solar energy can be utilised to power cooling and air-conditioning systems by two methods: electrically and thermally. In the electrical form, photovoltaic (PV) panels convert the sunlight directly into electricity to run conventional cooling systems.
It runs on solar power to generate power for cooling. The solar cooler works by converting the radiant energy from the sun into cold air that is pushed through moist cooling pads. This process results in evaporation and a drop in temperature.
In the electrical form, photovoltaic (PV) panels convert the sunlight directly into electricity to run conventional cooling systems. These systems are typically referred to as solar electric/vapour compression refrigeration (SE-VCR) systems and are sometimes called solar PV assisted cooling systems. Fig. 3 shows the main parts of SE-VCR.
Solar Cooling: Solar-powered air conditioners use the sun's energy to create cooling, thereby using less energy and emitting fewer greenhouse gasses. Absorption and diffusion systems are the two different categories of sun cooling systems.
Additionally, solar cooler provides economic benefits as it saves on the cost of operating an AC cooling system. A solar cooler works by converting the radiant energy from the sun into electricity, which is then stored in a battery.

Compressed Air Energy Storage (CAES) and Liquid Air Energy Storage (LAES) are innovative technologies that utilize air for efficient energy storage. CAES stores energy by compressing air, whereas LAES technology stores energy in the form of liquid air.

Compression of air creates heat; the air is warmer after compression. Expansion removes heat. If no extra heat is added, the air will be much colder after expansion. If the heat generated during compression can be stored and used during expansion, then the efficiency of the storage improves considerably. There are several ways in which a CAES system can deal with heat. Air storage can be, diabatic,, or near-isothermal.
