Comparative Analysis of Applications Off-Grid PV System and On-Grid PV System for Households in Indonesia

In Indonesia, about 89.75% of all power stations use fossil fuels, and only 10.25% generation uses renewable energy, i.e., hydropower generation, geothermal power, solar power and wind power. The use of fossil fuels such as coal, oil, and gas will cause environmental degradation. To help reduce environmental degradation requires the use of renewable energy such as solar energy through power plants in large quantities. In this paper will discuss solar power technically and economically, in this case, the cost of generation per $\mathrm {k}\mathrm {W}\mathrm {h}$ for each solar generating scheme is rooftop Off-grid photovoltaic (PV) system and on- grid PV system. Two schemes were created to calculate the generation cost per $\mathrm {k}\mathrm {W}\mathrm {h}$ for off-grid and grid-connected PV systems based on component prices for several cities in Indonesia. Electricity generation cost per $\mathrm {k}\mathrm {W}\mathrm {h}$ for off-grid PV systems and grid-connected PV system are respectively 4,644 IDR/kWh and 1,244 IDR/kWh compared to PLN electricity tariff is 1,467.28 IDR/kWh.
