Customer ServiceHe has been reporting on solar and renewable energy since 2009. Scientists in Egypt have investigated the effectiveness of using water and a mixture of aluminum oxide and calcium chloride hexahydrate to cool PV modules. Optimal performance was observed with a solution of 75% water, according to the research findings.
The water-based cooling system was found to increase the solar cells performance higher than the air based cooling system. Dubey and Tiwari designed an integrated combined system of a photovoltaic (PV) panel with a thermal (T) solar water heater. The hybrid PV/T solar system has been designed and tested in outdoor condition of New Delhi.
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.
Water cooling of PV panels is also studied by Irwan et al. where the performance of PV panels was compared with panels cooled by water flow on the front surface. The study was conducted under laboratory conditions. Water was sprayed on the front face of the panels. A water pump was responsible for spraying water in the cooling system.
The amount of water flowing through the cooling system depends on the intensity of solar radiation reaching the system. This radiation is also responsible for increasing the volume of gas in the expansion device. The proposed solution increased the electrical efficiency of the PV panels by 8.3%.
A water spray technique was constructed by Moharram et al. to cool solar panels. The device comprises of P.V. modules, a storage tank, a pump, spray nozzles and recycling system. With the use of water spray, the solar panel temperature reduces to 35 °C. 3.5. Phase change material (conductive)
