Simulation of a 10 kW Photovoltaic System in Areas with High Solar Irradiation

Problem statement: This study investigates the design and the simulation of a 10 kW photovoltaic (PV) system in areas of high solar irradiation. The importance of this study is to explore the feasibility of connecting the PV system with a grid to generate electricity at campus of Hashemite University (Jordan) whose yearly global irradiation is 2000 kWh/m². Approach: In order to determine the size and the number of PV modules needed to achieve the energy needs of the campus, we apply both the METEONORM and the PV SOL simulation software. This study calculates the cost of one kWh generated by the PV system and then compares it with the public electricity tariff. The study also presents a comparison between the performances of different PV panel sizes with different inclination angles. Results: METEONORM software data proves to be accurate and reliable to be used in this study. The 300W-panel-size shows the maximum energy generation. The optimal inclination angle which gives the maximum power generation is 27°. Conclusion: The calculations show the cost for PV-generation is $0.18 kWh⁻¹ without public subsidy compared to $0.086 kWh⁻¹ from national electric power company. A total of 356 modules are calculated to meet the power needs of the campus.
