Free QuoteA solar-based cooling system uses solar energy, in the form of heat or electricity, to provide cooling for air conditioning and/or refrigeration. The energy from the sun is captured using solar photovoltaic (PV) and transformed into electricity to drive vapor compression AC systems.
The cooling methods used are described under four broad categories: passive cooling techniques, active cooling techniques, PCM cooling, and PCM with additives. Many studies made a general review of the methods of cooling PV solar cells, especially the first three methods.
Natural cooling is preferable for small-scale solar PV-TE systems due to less input energy. Sky radiative cooling can produce the overall efficiency of PV-TE systems by about 35.7%. Using lower melting temperatures, PCM effectively cools the PV panels. Such PCM systems work passively without additional power input.
The indirect methods include parabolic troughs, linear Fresnel reflectors, solar power towers, panels, and dish systems [5, 6]. Researchers faced various challenges installing PV systems, such as high cost but lower efficiency. This persuaded them to work extensively on cooling the PV system [7, 8].
This review paper provides a thorough analysis of cooling techniques for photovoltaic panels. It encompasses both passive and active cooling methods, including water and air cooling, phase-change materials, and various diverse approaches.
Solar cooling is a technology for converting heat collected from the sun into useful cooling into refrigeration and air-conditioning applications. Solar thermal energy is collected and used by a thermally driven cooling process, which in turn is normally used to generate chilled water or conditioned air for use in the building.
