Comparative Analysis of Solar Charge Controller Performance Between MPPT and PWM on Solar Panels

Abstract

Solar power plants require other supporting equipment besides solar panels, including SCC (Solar Charger
Controller) for solar panel charger media to batteries. While the battery itself as a store of electrical energy generated
by solar panels. Therefore, other supporting equipment is very important in the application of solar power generation
systems.
In the charger system or battery charging on solar panels, an SCC solar charger controller is needed as the charger
media. In the solar charger controller there are two types between MPPT (Maximum Power Point Tracker) and PWM
(Pulse Width Modulation). This study aims to analyze the performance comparison between SCC which is good for
solar panels in battery charging. Apart from the comparison tool, the simulation tool used in this study is which one
is superior between MPPT and PWM. The way of comparison is to compare the current and voltage results obtained
from the SCC input and output between MPPT and PWM to find out which one is superior.
The results of the comparison with simulation produce current input from MPPT between 10, 15, 20, 25 A while PWM
input current is between 10, 15, 20, 15A. The results of the MPPT current output are between 12, 18, 21, 25A, while
the PWM output current is between 8, 18, 21, 25A. For the MPPT input voltage results are between 29, 25, 36, 41V,
while the PWM is between 26, 29, 36, 41V, while the output MPPT voltage is between 14, 14, 15, 15V, while the PWM
is in the range of 14, 14, 15, 15V.
