Abstract
World energy consumption increases with time, so that occur an energy imbalance. Many breakthroughs have developed to utilize renewable energy. The photovoltaic system is one of the easy-to-use renewable energies. The power conversion from PV fixed is still low, so the PV system is designed using the active dual-axis solar tracker. The PV tracker position can be adjusted to change the sun position to get maximum efficiency. The active dual-axis solar tracker system is integrated with the maximum power point tracking (MPPT) algorithm to keep PV operating at a maximum power point even though input variations change. The active dual-axis solar tracker system integrated with the maximum power point tracking (MPPT) algorithm to keep PV operating at a maximum power point even though input variations change. Tracking test simulation had done by comparing the output power of a fixed PV system with the active dual-axis solar tracker. Type-2 fuzzy logic based MPPT successfully increased the average output power by 10.48 % with the highest increase of 17.48 % obtained at 15:00 West Indonesia Time (GMT+7). The difference in power from a fixed PV system with the active dual-axis solar tracker of 36.08 W is from the output power worth 206.3 to 242.4 W.
Highlights
Review statistics that record the consumption of energy in the world showed there are increased significantly since the year 2006 until 2016
3.1 Simulation test of maximum power point tracking (MPPT) tracking based on fuzzy logic type-2
Tracking simulation is carried out to know the comparison of MPPT controller output power based on fuzzy logic type 2 that previously design with variations in climatic conditions
Summary
Review statistics that record the consumption of energy in the world showed there are increased significantly since the year 2006 until 2016. The use of renewable energy in Indonesia is still very limited. Indonesia has the potential renewable energy more than 441 GW newly realize 8.89 GW. Semiconductors material in solar cells absorb rays of the sun and broke the electron from the atom, which becomes energy electricity [3], but the conversion efficiency of PV normal still low [5]. Module PV can collect a lot of energy and an increase in efficiency when combined with the solar tracker system. The use of total solar tracker dual axes on PV able to enhance the efficiency of energy amounted to 40 % yr–1 [6]
