Abstract
The efficiency of energy productivity produced by solar panels is influenced by temperature. For example, on a solar panel PV-AD175MF5 with 175 Watt power, this has a temperature coefficient of -0.45% / ºC. When the temperature increase exceeds the Standard Test Condition (STC) of 25 ºC, it causes a decrease in the energy productivity of the solar panels. The research aims to analyze the effect of temperature reduction on the productivity of thermoelectric-based photovoltaic. Thermoelectric is used as the main component in research to reduce the temperature of this solar panel. Measurements were made in 3 conditions and 3 voltage variations for condition 3, namely (i) without turning on the thermoelectric and fan, (ii) with turning on the thermoelectric and without turning on the fan, and (iii) turning on the thermoelectric and turning on the fan. Changing the voltage and condition variables in thermoelectric is used to find the best performance results from solar panels. From the experimental results obtained, thermoelectric has succeeded in reducing the temperature of the solar panel. The voltage drop has an impact on increasing the temperature reduction. In addition, energy production has increased by 9.1 Watt, but efficiency is difficult to achieve because the thermoelectric cooling system requires minimum power consumption of 23.5 Watt. The potential advantages of thermoelectric cooling systems arise in the increase in lifespan or duration of the solar panel life. A decrease in temperature will reduce the risk of overheating in the solar panel.
