Integrated thermal photovoltaic (PV / T) can improve the performance of solar panels by maintaining the temperature of
the panels and utilizing solar panel heat as a source of hot water. The research was conducted to evaluate thermal solar
panels using cooling pipes. The results showed that the average intensity of solar radiation was 976W / m2
, the temperature
of the solar panels continued to increase all the time at an initial temperature of 32.5oC to a maximum temperature of
70.2oC and an average temperature of 56.7oC. The high value of solar radiation intensity throughout the day caused the
temperature of the solar panels to also The effect of heat from solar panels causes the voltage of the solar panels to also
change, the highest average voltage is 17.2V for panels using serpentine cooling pipes, while the voltage of solar panels
without serpentine cooling pipes is 15.6V.
