6 FAQs about [Spray water on the surface of photovoltaic panels to cool down]

Can a water spray cooling technique be used simultaneously on a PV panel?

The objective of this paper was to develop an experimental setup and to investigate a water spray cooling technique, implemented simultaneously on the front and back side of a PV panel as well as other different water spray cooling circumstances to ensure gained result comparison and to offer an optimal cooling solution (regime).

Does water spray cooling affect photovoltaic panel performance?

An experimental study was conducted on a monocrystalline photovoltaic panel (PV). A water spray cooling technique was implemented to determine PV panel response. The experimental results showed favorable cooling effect on the panel performance. A feasibility aspect of the water spray cooling technique was also proven.

Can water spray cooling be used on a monocrystalline photovoltaic panel?

Conclusions In this paper, a water spray cooling technique was proposed and experimentally tested on a monocrystalline photovoltaic panel for different cooling circumstances (regimes). The best cooling option turned out to be simultaneous cooling of front and backside PV panel surfaces.

Does water spray cooling technique affect PV panel temperature reduction?

Water spray cooling technique effect on PV panel temperature reduction As it was expected, the operating panel temperature was decreased in general due to the total cooling effect (evaporation contribution), but specific temperature reduction in the mean PV panel temperature was different, depending from the cooling circumstances (regime).

When to start cooling of PV panels based on water spraying?

A cooling system has been developed based on water spraying of PV panels. A mathematical model has been used to determine when to start cooling of the PV panels as the temperature of the panels reaches the maximum allowable temperature (MAT).

How to cool a PV panel?

Jakhar et al. used the water as the coolant in the PV panel. They set the water channels at the rear of a PV panel. Their results showed that this system can increase the efficiency of the PV panel. Chandrasekar and Senthilkumar cooled down the PV panels by the heat spreaders in conjunction with the cotton wick structures.
