Energy Yield Of Photovoltaic (PV) Systems Supporting Hybrid Power Generation In Bontang City, Indonesia

Energy consumption increases as population grows. Selection of the hybrid system architecture is a prerequisite of success to obtain greater energy production. In rural areas, these problems can be overcome by using automation integration of two or three Local Energy Sources (LES) through the model renewable energy hybrid power plant. Mostly, the hybrid combination in rural area is photovoltaic systems supported by diesel generator in case of insufficient energy production. The energy production photovoltaic systems are influenced by environmental parameters, such as irradiation, temperature and these electrical outputs determine the efficiency of other components when making energy estimation. The proposed design of hybrid power generation consists of photovoltaic array (WP100), charge controllers of Phocos 5A and 10 A, diesel generator of 1.3 kW, inverter DC/AC 1.0, the storage system with 3 pieces of 50Ah battery bank, programmable logic controller (PLC) with I/O 16. The results of this study show that in average solar radiation of 6.43 kWh/m2, the photovoltaic systems produce energy of 34.43 kWh and energy supply to load system is about 33.60 kWh. The average efficiency performance of proposed system is 40% with the promising system operation of 2.34 hours/day and potential sunlight irradiation of 5.74-6.43 hours/day
