However, cooling by spraying water using a fan is not an efficient method, since the water will not be sprayed over the whole panel, and therefore, some parts of the PV panels will not be cooled, as well as this method results in a very high water loss. Tang et al. designed a novel micro-heat pipe array for solar panels cooling.
The cooling component in the design is an atmospheric water harvester (AWH). The AWH collects atmospheric water vapour by a sorption-based approach in the evening and at night, and then the sorbed water is vaporized and released during the day by using the waste heat from the PV panel as energy source 27, 28, 29, 30.
The results of the photovoltaic panel with the pulsed-spray water cooling system are compared with the steady-spray water cooling system and the uncooled photovoltaic panel. A cost analysis is also conducted to determine the financial benefits of employing the new cooling systems for the photovoltaic panels.
Cooling the PV panels by water every 1 °C rise in temperature will lead to the fact that the energy produced from the PV panels will be consumed by the continuous operation of the water pump.
The objective of the research is to minimize the amount of water and electrical energy needed for cooling of the solar panels, especially in hot arid regions, e.g., desert areas in Egypt. A cooling system has been developed based on water spraying of PV panels.
In most cases, the cooling system with the steady-flow design was used to cool down and control the temperature of the PV panels in the previous studies. However, these systems consume considerable amount of water, which can be a major problem for large scale PV power stations.
