ABSTRACT

The national solar power potential is equivalent to 207,898 MW, but only 0.05% or 100 MW has been utilized.Energy sources from the sun are one of the alternative choices because of their abundant availability and lower levels of pollution than fossil fuel power plant. This is what makes photovoltaic system technology one of the most popular renewable energy technologies in the world In this study, electric energy needs for PT X was determined to be 2162 watt-hour, with 2 units of AC ? pk, 2 units of LED television, 2 units of refrigerator, 2 units of washing machine, 1 unit of rice cooker, 8 units of lamp, and 5 units of computer. So, the total estimated electricity need for PT X is 13,000Wh/day. For solar panel plan requirement, the results of the analysis with the capability of 200 wp/panel showed a total need of 16 pieces with the arrangement of 3 on the x and y axes being 6, with a total voltage obtained being 105 volts and the total output current being 30 amperes with a total power of 3133 WP. The demand charge controller needed is 3 amperes and the inverter capacity is 3937 watts. For power storage, the required battery capacity is 4025 Ah, so it takes 4 batteries with a capacity of 2 volts 1000 ampere hours. Based on the simulation results that have been carried out, the estimated total electrical energy that can be generated for one year by off-grid Solar Power System is 13 KWh/day. This Design is able to meet the needs of the branch office electricity load of 95.85%.
