Planning Of Hybrid Rooftop Plts (Pv-Pln) As A Source Of New Renewable Electrical Energy In Class II B Prison In Banjar City Using Homer Software

Abstract

The Problem of increasing demand for electrical energy and dependence on fossil energy sources encourages the need for the utilization of new renewable energy, one of which is solar energy. This research aims to plan a Hybrid Rooftop Solar Power System (PV-PLN) at the Banjar City Class II B Penitentiary using HOMER software as a simulation and optimization tool. Simulation results using HOMER show that with a generating capacity of 160 kW produces an average power output of 567 kWh/day with a total production of 206,779 kWh/year, the plant shows that the grid system produces a Net Present Cost (NPC) of Rp 5.13B with an operating cost of Rp 397M while the Hybrid System produces an NPC of Rp 4.24B with an operating cost of Rp 186M and requires an initial investment of Rp 1.84B, but the investment results obtained are more favorable to the hybrid system with a present worth of Rp 886,756,000, an annual worth of Rp 68,594,460 per year, a Cost of Energy (COE) of (908/kWh), a Return on Investment (ROI) of 7.4%, an Internal Rate of Return (IRR) of 10.8%, a Payback Period of 7.5 years, and a discounted Payback Period of 11.84 years.
