Analyzing the Performance of a 2.72kWp Rooftop Grid-tied Photovoltaic System in Tarlac City, Philippines

Residential and industrial areas are using rooftop grid-tied Photovoltaic (PV) systems, which are becoming increasingly popular. This is because solar energy reduces electrical consumption and provides free energy, while also lowering carbon emissions to create a more sustainable environment. This paper aims to analyze the 2.72kW p rooftop grid-tied PV system performance between 2020 and 2023 in Tarlac City, Philippines. The PV generated yearly is measured by Array Yield (YA), Reference Yield (YR), and Final Yield (YF), which were found to be valued at 3.12, 3.9, and 3.01 kWh/kWp, respectively. The efficiency can decrease due to System Loss (LS) and Capture Loss (LC), which were 0.78 and 0.12 kWh/kWp, respectively. This results in a Capacity Utilization Factor (CUF) of 15.52% and a Performance Ratio (PR) of 77.10%. The productivity of PV resulted in an array efficiency was 12.89%, an inverter efficiency was 94.3%, and a system efficiency was 12.16%. PV energy generation was 3,699 kWh, with 2380 kWh fed into the grid annually. The system's annual revenue is $690.59. The payback period is 6 years with a 238.2% Return On Investment (ROI). Carbon emissions are reduced by 0.379 tCO2/kWp/yr.
