Abstract

In industry, an inverter is a tool/component for adjusting the speed of an electric motor. By using an inverter for electric motor purposes, it becomes a variable speed, whereas the speed can be changed or adjusted as needed. The method used in this study is an experimental research method, namely designing and measuring the system under study. Measurements are made for non-electrical quantities, namely the inverter of the solar module which is generated by the intensity of sunlight hitting the surface of the solar cell. Measurements are also made for electrical parameters such as current, voltage, power factor, and power. Based on the data obtained from all the tests that have been carried out, the system output voltage cannot reach the expected 220 Volts. Because changes in load affect the output voltage of the system were occurred, as the load of 60 W/220V is added, the output voltage drops to 740.5 Volts. As the load is reduced by 60W/220 V, the output voltage increases by 786.9 Volts, within the average inverter efficiency of 77%.

Abstract

Electric energy is essential in modern life, with solar power emerging as a leading renewable energy source. Photovoltaic (PV) systems convert sunlight into electricity, but their output is highly sensitive to environmental changes such as solar irradiance. A reliable Maximum Power Point Tracking (MPPT) method is needed to maximize efficiency, This study investigates the performance of a Buck-Boost DC-DC converter integrated with the Incremental Conductance (InCo) algorithm for MPPT in PV systems. A comparative analysis is conducted between systems with and without MPPT under variable irradiance conditions, replicating real-world scenarios like partially cloudy weather. Simulations were performed in MATLAB Simulink using a PV module model based on actual datasheet parameters. A digital lux meter was used to simulate light intensity fluctuations. Results show that the MPPT-enabled system effectively tracks the Maximum Power Point (MPP) even during rapid irradiance changes. On average, the system achieved improvements of 65.53% in output voltage, 65.48% in current, and 86.47% in power compared to the non-MPPT configuration. These findings demonstrate that combining the InCo algorithm with a Buck-Boost converter offers an efficient and adaptive solution for improving energy conversion in PV systems in environments with unstable solar exposure.
