Abstract

The planning of an On-Grid Solar Power System (PLTS) at PT. HIT Polyfoam Production Building aims to improve energy efficiency and reduce carbon emissions. The system is designed using Jinko 545 Wp solar panels, Huawei 50 kW inverters, and a monitoring system to inject energy into the MDP/SDP busbar with a PLN power capacity of 690 kVA. Economic analysis shows a life cycle cost of IDR 3.57 billion, energy cost of IDR 531.61/kWh, a positive Net Present Value (NPV) of IDR 119.63 million, a Profitability Index (PI) of 1.04, and a Discounted Payback Period (DPP) of approximately 28 years, indicating the investment is feasible. Additionally, the system can reduce carbon emissions by around 403 tons CO₂ per year, supporting industrial decarbonization.
