The use of cow fats as energy storage materials in photovoltaic systems
These data are data of temperature change test results on the top surface of photovoltaic (PV), bottom of PV, on cow fat, and PV output voltage. In this research used two PV. One standard PV, and one using cow fat as heat energy storage. Testing begins in the morning at 8:00 to 18:00 afternoon. Temperature sensors are used thermocouples, which are connected to the data acquisition system. Data is recorded every 5 seconds.
