About Principle of Photovoltaic Panel Spray Cooling System
The electrical efficiency of the PV panel, I–V characteristic curves, temperature of cells, and the amount of water consumed during the cooling process are investigated for two cooling systems. The results of the PV panel with the pulsed-flow spray cooling system are compared with the steady-spray water cooling system and the uncooled PV panel.
The electrical efficiency of the PV panel, I–V characteristic curves, temperature of cells, and the amount of water consumed during the cooling process are investigated for two cooling systems. The results of the PV panel with the pulsed-flow spray cooling system are compared with the steady-spray water cooling system and the uncooled PV panel.
The operating principle of this cooling type is based on water use. Water cooling includes free convection, water spray, heat pipes or immersion techniques. The flowing or sprayed water removes heat from the PV panel, lowering its temperature. A schematic water cooling system is shown in Figure 5.
Cooling solar panels with water shows potential for boosting their efficiency. Methods like water spraying, immersion, circulating liquids through tubes or microchannels, water jet impingements, and evaporative cooling demonstrate efficiency gains of 13 % to 66 % compared to other approaches (Fig. 28).
This study investigates the impact of cooling methods on the electrical efficiency of photovoltaic panels (PVs). The efficiency of four cooling techniques is experimentally analyzed. The most effective approach is identified as water-spray cooling on the front surface of PVs, which increases efficiency by 3.9% compared to the case without cooling.
Achieves hot water production as a part of the cooling system. In this study, the authors introduce a pioneering method involving water spraying on PV panels' front surface, with controlled water flow (2–3 L/min), meticulously assessing system performance, exergy and energy aspects, and the impact of dust.
