Solar irradiation is clean, readily available, abundant and is famous as a renewable energy source. Solar Photovoltaic (PV) system power plant with hybrid system is introduced as a potential solution to fulfil electricity demand for off-grid areas, such as Jifak Village, Asmat Regency, Papua. In 2018, the electricity network coverage area was only 57.03% in Papua Province, Indonesia. On the other side, this region consistently receives high solar radiation intensity for an average 4.68 kWh/m2 per year. The research objective is designing suitable solar Photovoltaic (PV) system module, which will be utilized further in Jifak Village, Asmat Regency. This developed hybrid PV System model is featuring PV module, a boost converter, Maximum Power Point Tracker (MPPT) method with applied Incremental Conductance Algorithm for tracking maximum power point, storage battery model, a single-phase inverter model, generator set (Genset) and communal load model. Hybrid PV system is developed using MATLAB/SIMULINK program, and result verification are conducted using HOMER Pro program. MATLAB/SIMULINK program chosen due to its customization capability for hourly data input. Meanwhile, HOMER Pro program is only accommodating average monthly data input. MATLAB/SIMULINK customization ability is the driving system for incorporating more comprehensive PV performance. In this research, the proposed model showed that maximum power point was always located at the expected position, readily tracked, and maintained by increasing and decreasing irradiation profile variable. The research also showed that energy output, equal to at least 40 kWh was able to supply electricity as the communal load for 100 households in Jifak Village, Asmat Regency, Papua province.
