6 FAQs about [Water guide trough in front of photovoltaic panel]

Should PV panels be cooled by water?

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.

How to control the operating temperature of photovoltaic cells?

This work, has been reviewed the studies and research conducted in recent years on cooling techniques and controlling the operating temperature of photovoltaic cells and analyzed the results. These methods include natural air cooling, forced air cooling, passive water cooling, active water cooling, and pcm cooling.

What temperature should a PV panel be before and after cooling?

The temperature of the PV panel before and after cooling is 45 °C and 35 °C, respectively. It is assumed that the maximum allowable temperature of the PV panel is 45 °C, beyond which cooling of the PV panel should start by water spraying of the panels till its temperature goes down to 35 °C.

What is the cooling rate of PV panels?

If the pump is operated such that it sprays water over the PV panels at a flow rate of 29 l/min, this will result in cooling of the PV panels from the MAT of 45 °C to 35 °C in 4.7 min. In this case, it can be concluded that the cooling rate of the PV panels is ∼2.0 °C/min, and the water spraying should be stopped after 4.7 min. Figure 3.

When do PV panels produce the highest output energy?

Based on the heating and cooling rate models, it is found that the PV panels yield the highest output energy if cooling of the panels starts when the temperature of the PV panels reaches a maximum allowable temperature (MAT) of 45 °C. The MAT is a compromise temperature between the output energy from the PV panels and the energy needed for cooling.

Does cooling by water affect the performance of photovoltaic panels?

An experimental setup has been developed to study the effect of cooling by water on the performance of photovoltaic (PV) panels of a PV power plant. The PV power plant is installed in the German University in Cairo (GUC) in Egypt. The total peak power of the plant is 14 kW.
