This study focuses on the design and performance optimization of a grid-connected solar photovoltaic (PV) system intended to meet the energy demands of the Computer Center at Al-Zaytoonah University in Jordan. The PV system simulation was conducted using PVsyst software, with parameters tailored to the geographical location of the site (Latitude: 31.96°N, Longitude: 35.93°E) and local meteorological data. The selected configuration includes 90 JinkoSolar JKM 370M-72 PV modules paired with a SUN2000-33KTL-US inverter, providing a total system capacity of 33.3 kWp. By evaluating different orientations, the optimal setup was determined to be a fixed tilt angle of 27° and an azimuth angle of 0°, resulting in an annual energy output of 59.727 MWh, a performance ratio of 84.3%, and a specific energy yield of 1794 kWh/kWp/year. In addition to energy performance, the study assesses the economic and environmental impacts of the system. Simulation results estimate that the system will prevent approximately 837.732 tons of CO₂ emissions over a 30-year period. Financial analysis indicates a payback period of approximately 1.86 years, with expected cumulative savings exceeding 816,000 Jordanian Dinars over 20 years—largely due to rising electricity tariffs. These findings confirm the feasibility and sustainability of solar PV installations for institutional use in Jordan and similar regions. The study presents a replicable design approach, supported by real-world performance simulations, which can serve as a valuable reference for integrating renewable energy solutions into educational facilities.
