How can solar energy be used to power cooling and air-conditioning systems?

Overview of SCACSs 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.

Do solar energy systems generate heat?

In recent years, research communities have shown significant interest in solar energy systems and their cooling. While using cells to generate power, cooling systems are often used for solar cells (SCs) to enhance their efficiency and lifespan. However, during this conversion process, they can generate heat.

Can solar energy be used as a cooling system?

Utilising renewable energy sources for cooling systems, predominantly powered by solar energy, has become one of the forefront technologies that attracted engineers and responsible authorities as such systems associated with the shining sun period.

How do solar cooling systems work?

Solar cooling systems use solar thermal energy to generate cooling for a building. The most common method is an absorption chiller that uses captured solar heat to produce chilled water, which is then circulated through the building for space cooling, reducing the need for traditional air conditioning.

How can solar cells be cooled?

Various cooling techniques can be employed to cool solar cells, including passive cooling methods, such as natural convection and radiation, and active cooling methods, involving the use of a water-spray cooling technique (Figure 4) . Figure 5 shows the immersion of polycrystalline solar cells in water .

Can photovoltaic systems be compared with cooling systems?

The comparison of cooling systems in photovoltaic (PV) systems is a critical aspect in undertaking research to enhance the overall efficiency and performance of solar energy conversion.
