Technical Analysis on Household-Scale Rooftop Solar Power Plant Design with On-Grid System in Semarang City

Indonesia has 442 GW total of potential renewable energy equivalence which can be used for electricity generation. However, the energy utilization in 2018 is only 8.8 GW or 0.019% of total potential renewable energy, while the biggest renewable energy potential is at 207.8 GWp. By also considering the growing number of household customers, utilizing the rooftop as the base of solar power plant generators can be an effective and efficient solution. The purposes of this research are to technically design and analyze the household-scale rooftop solar power plant potential with an on-grid system. Through the utilization of PVSyst 6.43 software and a variety of main components, this household-scale rooftop solar power plant potential performance planning is expected to generate 4.23 kWh / kWp per day.
