The use of beef tallow as a thermal energy storage material in photovoltaic systems

Research has been carried out on the use of weak cows as a heat energy storage material in a photovoiltaic system. In this study, beef fat is placed at the bottom of the PV panel which functions to absorb heat on the PV surface.
The data displayed is the result of testing the temperature changes on the top surface of the photovoltaic (PV) and the bottom of the PV. In this study, two PVs were used. One is standard PV, and the other uses beef fat as heat energy storage. Testing starts in the morning at 08.00 to 18.00 in the afternoon. The temperature sensor uses a thermocouple, which is connected to a data acquisition system. Data is recorded every 5 seconds.
