Analisis Tekno Ekonomi Sistem Fotovoltaik Pada Gedung Edutorium KH. Ahmad Dahlan Universitas Muhammadiyah Surakarta Menggunakan System Advisor Model (SAM)

The increasing demand for electrical energy requires alternative energy sources that are environmentally friendly and sustainable. One promising solution is the Photovoltaic (PV) Solar Power Plant (PLTS), which converts solar radiation into electrical energy directly. This study aims to analyze the technical and economic feasibility of implementing a photovoltaic system on the roof of the Edutorium KH. Ahmad Dahlan Building at Universitas Muhammadiyah Surakarta using the System Advisor Model (SAM) software. The research methodology includes solar radiation data collection, PV system design, performance simulation using SAM, and economic analysis through parameters such as Life Cycle Cost (LCC), Cost of Energy (COE), Net Present Value (NPV), Internal Rate of Return (IRR), and Discounted Payback Period (DPP). The simulation results indicate that the PV system with 1,032 monocrystalline modules rated at 480 Wp, 17 inverters, and 306 VRLA AGM batteries produces an annual energy output of 605,004 kWh with a performance ratio of 0.76. The total estimated investment cost is Rp 12,066,200,000, with a Cost of Energy of Rp 1,232/kWh. The economic analysis shows a positive NPV, an IRR higher than the discount rate, and a DPP shorter than the 20-year project lifetime, confirming that the PV system implementation at the Edutorium KH. Ahmad Dahlan UMS is technically and economically feasible.
