Abstract
The use of solar energy has begun to be developed in PLTS, but the photovoltaic module electricity produced is not at maximum output power. To increase the efficiency of the photovoltaic module, Maximum PowerPoint Tracking (MPPT) technology is used. Differences in the level of solar energy irradiation can cause the output power of the solar panels to vary and will not be maximized. Changing temperature and irradiation can be maintained with a maximum voltage of 40Volt and according to what is desired. In this study, MPPT consists of a Boost Converter whose function is to regulate the output voltage, while the algorithm used is the fuzzy logic which works based on Error (E) and Change Error (CE) from changes in the voltage and current of the photovoltaic module. The results showed that after using MPPT when input was given a change in load resistance with irradiation of 1000 W/m2 and a temperature of 25 ℃ resulted in a difference in power under different conditions compared to a system without MPPT. The power generated without the use of MPPT has a significant change with the results of 227.7W, 114.4W, 76.5W, 57W, and 45.5W. Testing the system after installing the MPPT when given an input change in irradiation with a load resistance of 20 Ω and a temperature of 25°C, a more stable power is produced with a value of 0.008W. Then when the input changes to irradiation with a load resistance of 20 Ω and a temperature of 25 ℃, the maximum power produced for each of the highest irrigation is 746.9 W/m2, 779.4 W/m2, and 839.4 W/m2 of 38.88 W, 42.07 W, and 47.8 W and compared to the system without MPPT only 21.76W, 21.96W and 22.28W.
