This paper presents a design and performance analysis of a 5 kVA hybrid solar photovoltaic (PV) system tailored for residential applications in Port Harcourt, Nigeria. The purpose of this research is to design an optimal solar PV system configuration and rigorously evaluate its technical performance and economic viability through a detailed load assessment of a typical Port Harcourt residence. The PV Syst software was used for the simulation, suitable PV modules (mono 550 Wp), inverters (5kVA), batteries (deep-cycle gel, 12V, 200Ah) and charge controllers (MPPT 150Ah, 48V) were selected for optimal operation. Simulations showed that the annual energy requirement for the Household is 18.56 kWh (6774.4 kWh/day) and the energy available through solar panel is 7675.5 kWh, where the energy supplied to the user is 6099.0 kWh (16.71 kWh/day) a slightly less than the required load, which may be due to some losses. The detailed load assessment revealed total daily energy consumption of 18.21 kWh, including a 20% safety margin, net usable daily energy yield of 18.56 kWh from the 5.5 kWp solar array, effectively meeting the 18.21 kWh daily energy demand, the system offers significant long-term economic advantages by displacing costly generator fuel consumption and maintenance. The system can meet power needs while minimizing energy waste and maximizing solar energy use.
