Abstract
Renewable energy sources that photovoltaic is promising CO2 free alternatives. Photovoltaic has the smallest efficiency value compared to electricity generation from other sources. The effort to increase the efficiency of photovoltaic can use the Maximum Power Point Tracking (MPPT). The purpose of the MPPT method is to find the maximum power point of the photovoltaic. In this research, optimize maximum power point photovoltaic using MPPT Incremental Conductance (MPPT IC) based PID controller. The DC-DC converter used is the SEPIC converter. The advantage of the SEPIC converter is that the efficiency produced is better than the Buck-Boost converter and Chuck converter. Another advantage of SEPIC Converter has non-inverting output voltage polarity with the input voltage. The results of this study found that using the MPPT IC based PID controller can increase efficiency power output photovoltaic than using MPPT IC conventional.
