Experimental Method for Improving Efficiency on Photovoltaic Cell Using Passive Cooling and Floating Method

Electrical energy is the key to the development of human civilization, it causes an increase in electricity production using fossil fuels. This causes the emergence of the need for electricity generation with renewable energy sources. This research discusses the improvement of efficiency in photovoltaic cells (PV) by using the floating method and also the cooling method, especially, passive heatsink cooling. Tests carried out measures the performance of PV panels by measuring the influence of floating and cooling methods. The data shows that the increase in power is 30.54% with floating method while using passive heatsink cooling only increase power output by 14.31%. The temperature in the PV panel tends to increase with increasing intensity of solar radiation. In addition, both methods resulted in increase of the PV panel temperature by 6.42% and 0.60% for floating method and passive heatsink cooling respectively.
