In recent years, there has been a significant increase in the installation of solar photovoltaic (PV) systems worldwide. This paper presents a comprehensive analysis of the cost-effectiveness of this renewable energy source based on tilt and azimuth angles. An economic study is conducted to analyze the net present value (NPV) in relation to the tilt angle. In a smart grid power system, reliability performance is crucial and requires additional attention. Furthermore, the integration of Battery Energy Storage (BES) schemes, solar photovoltaic (SPV), and wind systems in the smart grid system offers significant efficiency and reliability to utilities. However, grid coordination with PV and other resources can lead to issues such as power interruptions or outages. The objective is to demonstrate how the tilt angle, along with other PV factors can optimize the overall net present value of the system. The findings from this study will contribute to a better understanding, management, planning, forecasting, and stabilization of solar power generation.
