Optimization of Solar Panel Efficiency: Control the Maximum Power with the Fuzzy Logic Method

Introduction

Solar panels have become a popular renewable energy solution, converting sunlight into electrical energy. However, the efficiency of converting solar energy into electricity is still an obstacle. The installation of static solar panels, as well as changes in the intensity of sunlight throughout the day, causes fluctuations in the power output produced. To overcome this problem, this research carries out the design of the MPPT type solar charger controller with the Fuzzy Logic method based on Microcontroller ATmega328. This system is designed to maximize the utilization of the energy produced by the solar panel, by maintaining the output voltage stable at 14V, despite environmental conditions and loads.

The MPPT Fuzzy Logic System: A Control System for Solar Panels

The MPPT Fuzzy Logic system works by utilizing the Fuzzy Logic Controller (FLC) method. FLC is a control system that can overcome uncertainty or diversity in input data, such as voltage fluctuations and currents produced by solar panels. FLC acts as a "brain" in this MPPT system.

Input: Measuring Solar Panel Data

FLC receives data input in the form of voltage and current from the solar panel measured by the sensor. The data is then processed to determine the condition of the solar panel.

Fuzzy Logic: Programming Fuzzy Rules

FLC uses Fuzzy rules that have been programmed to determine the value of the duty cycle on the PWM (Pulse Width Modulation) module. The duty cycle determines the width of the pulse fed to the Switch DC-DC converter, which in turn regulates the output of the solar panel voltage.

Output: Controlling the DC-DC Converter

FLC produces output in the form of PWM control signals that control the Switch DC-DC converter to reach the maximum power point from solar panels.

The MPPT Fuzzy Logic system has several advantages, including:

Maximum Efficiency: This system adjusts the output of solar panel voltage to environmental conditions, so that it can reach the maximum power point in various conditions of light and temperature intensity.
Output Stability: This system is able to maintain the output voltage at a stable 14V, regardless of voltage fluctuations and input current.
High Reliability: The use of Microcontroller ATmega328 provides reliability and flexibility systems in programming and implementation.
Ease of Monitoring: The results of the voltage measurement and solar panel current are displayed on the LCD, making it easier to monitor and evaluate system performance.

Application and Positive Impact

Design of the MPPT type solar charger controller with the Fuzzy Logic method based on Microcontroller ATmega328 has great potential to be applied in various fields, such as:

Distributed Power Plant System: Optimizing solar panel efficiency for household, office or community needs.
Battery Charging System: Ensuring battery charging with maximum efficiency, increasing battery life, and reducing charging time.
System of Monitoring and Controlling Solar Panels: Facilitate monitoring and control of solar panel systems, so as to increase the efficiency and reliability of the system as a whole.
