This study examines the techno-economic feasibility of replacing diesel-based power generation with optimized hybrid solar photovoltaic systems at Red Sea University in Port Sudan, Sudan. Using the College of Engineering as a representative technical model, the study conducted an appliance-level load audit and applied a diversity factor to distinguish between theoretical peak demand and realistic daily energy consumption. The analysis reduced the estimated maximum daily load from 622 kWh\/day to a calibrated operational baseline of 84.3 kWh\/day per functional unit. Based on this profile, the proposed system for each unit consists of a 20 kWp photovoltaic array, a 15-kW hybrid inverter, and a 45 kWh LiFePO\u2084 battery bank. The financial analysis demonstrates strong economic viability, with an estimated capital cost of 25.9 million SDG per unit and a university-wide investment of 466.4 million SDG for 18 units. At the current local fuel price of 6,880 SDG per liter, the project is projected to achieve a simple payback period of approximately 2.5 months and a first-year return on investment of about 378%. Sensitivity analysis confirms that the model remains financially feasible even under a 50% reduction in fuel prices, maintaining a payback period of about five months. Environmentally, full implementation would eliminate the consumption of more than 328,000 liters of diesel annually and reduce carbon emissions by approximately 820 tons of CO\u2082 per year. The study concludes that an empirically calibrated hybrid solar transition offers a technically reliable, financially self-recovering, and environmentally sustainable model for university energy infrastructure in resource-constrained contexts.<\/p><p style='text-align:left; direction:ltr;'><strong>Keywords: <\/strong> : Solar Energy Transition, Techno-Economic Feasibility, Hybrid PV System,
