Feasibility Study and Economic Consideration of Rooftop PV System for Replacing of Diesel Generators in Erbil City

This study compares a diesel generator and a rooftop photovoltaic system for energy sustainability. The comparison is based on economics, maintenance costs, life cycle cost analysis, and environmental impact. The PV system is sized and enhanced using hourly solar radiation and load data per hour, considering the minimum energy production cost and environmental impact. The article generally discussed solar systems to replace private generators in Erbil city, in terms of cost, and comparisons were made between PV solar systems and other sources of electricity, especially local diesel generators. According to the research, the PV system is a more economical and ecologically responsible option for grid electricity generation. Because of their minimal emissions, solar hybrid systems are an affordable and environmentally friendly choice for producing power. The results of this study are useful for areas with equivalent climates and energy supplies. However, investors and policymakers may find the sensitivity analysis of economic factors useful in determining the viability of renewable hybrid systems. A trend towards renewable energy sources, especially photovoltaic technology, an emerging technology, has resulted from the growing demand for power and the depletion of natural resources.
