International demand for EVs is only exceeded by the need for reliable and sustainable charging infrastructure. Oman may cut carbon emissions and fossil fuel use with this adjustment, but it strains the power infrastructure and requires solar-based EV charging facilities. A Muscat, Oman, solar-powered EV charging station using HOMER Grid software is examined technically and economically. System-level factors, including solar radiation, load demand dynamics, grid access, and project features, define an autonomous solar-powered EV charging station's optimal design and location. HOMER Grid simulates and optimizes processes. The assessment covers energy production, renewable percentage, and COE for several system designs. Thus, solar-only and grid-connected hybrid systems were evaluated on NPC, ROI, and LCOE. The study indicated that solar PV-based charging and battery storage minimize grid power demand and operational costs. The optimized system covers Muscat's EV charging needs with 97.9% renewable energy and 12543731kWh of annual energy production, saving $593,578/yr in bills and energy charges. Optimized solar-dependent systems base system COE $0.0362/kWh to -$0.0236/kWh suggested model, opposing grid-based charging stations. In addition to grid-connected EV charging, CO2 and greenhouse emissions may be reduced. As Oman's EV infrastructure needs expand, implementing solar EV charging stations in Muscat is technically and economically viable. If properly built, solar-charged EV stations may reduce CO2 emissions, increase energy security, and assist Oman in reaching its renewable energy targets.
