The current study investigates the effect of water spray cooling on the performance of a photovoltaic panel (PV). The advantage of this method compared to other methods is it provides surface cleaning besides the cooling effects which affects the long-term performance of the panel.
The literature review indicated that the efficiency of PV systems can improve considerably by using an efficient cooling technique. The previous studies conducted on the water spray cooling systems showed that the cooling of PV panel from the front is significantly better as compared with other cases [19, 20].
en the photovoltaic cell temperature is above the working temperature, thus requiring a cooling method. This research examines the cooling effect of photovoltaic panels using water spray with various types and diameters to reduce the temperature and performance of p
In this method, water is sprayed on the front or back of the panel surface, or both at the same time. Parameters such as water flow rate, number of nozzles, spraying height, and formation of water film are important. By spraying the water onto a photovoltaic panel, the operating temperature can effectively regulate through cooling.
The experimental tests are conducted to obtain the solar panel performance, namely output voltage, output current, output power, and panel efficiency under clean and dusty conditions.
The power output from the PV system before and after spraying water is shown in Figure 20. A maximum of 34W increase in power is found at 12.30 pm after spraying water.
In this section the effect of the cooling system on the output power and electrical efficiency of the panel is investigated and the results of the cooling system with 9 nozzles
