Recently, interest in solar energy has increased for many reasons, however, connecting solar power stations in distribution networks may cause many problems, so it was necessary to study the impact of connecting photovoltaic systems to distribution networks to provide solutions feasible in practice. This study includes analyzing the performance of a solar power plant with a capacity of 17.2 kWh connected to the low voltage network of the distribution networks according to Egyptian PV-LV code-2014, simulation using MATLAB/Simulink, and cost analysis for connecting SSPV 17.2 kW to LV distribution networks. The system model was built on MATLAB/Simulink and simulated under daily weather conditions to test the system's operational performance. Power quality parameters are measured using C.A. 8336 power quality analyzer at the inverter output side for the PV system at the Minya Electricity Distribution Sector in Minya Governorate, Egypt. The system produces a 29.314 MWh and reaches its initial cost in 7.2 years. The electrical energy produced by the system is directly injected into the low voltage network for loads of the Minya Electricity Distribution Sector building without batteries or storage devices (on-grid).
