<br/><br/> This study evaluates a 3.115 kW grid-tied solar PV system installed in a  residential household in Brgy. 56-B Bacsil South, Laoag City. The main objectives  were to determine the total initial cost of the system, monitor solar energy production  and usage, project financial aspects over 25 years, compute the ROI and PBP, and  assess the system’s effectiveness. Through a year of monitoring and data collection,  including historical electricity profiles and solar generation records, the system's  effectiveness was assessed. Results showed an initial investment of Php. 118,540.00,  with the system producing 4432.19 kWh over the monitoring period. A 25-year  projection estimated a gross saving of Php. 962,714.22, with an overall saving of Php.  802,540.79 after subtracting operating and maintenance costs. The investment was  projected to be recovered in 5.0515 years, demonstrating a speedy payback period; and  has an average annual return on investment of 27.7919%. Thus, the PBP for the optimal  redesigned size of the solar PV system was projected to be 2 years, 2 months, and 15  hours and has an ROI of 62.2154%, which was faster and more effective than the actual  size of the system presently installed. Redesigning the solar PV system, a kilowatt-peak  value of 1533.65 kW, satisfies the optimal condition. The study recommends  homeowners consider investing in grid-tied solar PV systems for long-term savings and  future solar designers size systems according to load to maximize savings.  Additionally, future research should explore different solar system types, such as  hybrid and off-grid, using this study as a basis for comparison.
