Solar panel is used to harvest solar energy through the photovoltaic panels to generate electricity. Due to the different intensity of the sun, the panel may be getting overheated during the operation which affect the performance. The research was conducted to analyse the efficiency of liquid immersion cooling technique with water, measure the differences of water and nanofluids under the liquid immersion technique, and determine the efficiency increase of the cooling system with additional cooling. The apparatus was set up to test the cooling system performance throughout the most active part of the day with sunlight. The collected data has shown an increase in the power efficiency of 12.66% in favour of silver nanofluid compared to water when the cooling system is attached with additional cooling capabilities. However, without the additional cooling capabilities, the difference in power output between silver nanofluid and water shows around 2.42% in favour of silver nanofluid. The use of nanofluid in this experiment indicates a noticeable increase in power efficiency through the ability to keep the panel better cooled throughout the day. This allows nanofluids to be used as a cooling fluid to remove heat form the solar panel. � Published under licence by IOP Publishing Ltd.
