Optimal PV System Design for a Residential in Cambodia

This project is to design and study three systems to select the best and most economical system for housing: The Hybrid Photovoltaic system use 16 solar panels with a power of 4480 W and 24 batteries with a capacity of 910Ah and 43.68 kW. Economics study of this system is costs $ 13,340 and earns $ 895 per year from the system. Using this system is not economically profitable for housing up to -511%, equivalent to $ 68,235 according to an 18-year study. The On-Grid Photovoltaic System no battery backup studies two conditions: The average of charge conditions, using two solar panels at a cost of $ 478 and earning $ 101 per year, this system can benefit consumers 161%, equivalent to $ 770. The maximum of conditions, there are 3 solar panels, cost $ 582 and earn $ 140 per year, for this system there is a fast payment, which can save users up to 235%. equivalent to $ 1368.The On-Grid Photovoltaic System with battery backup is the same as the On-Grid Photovoltaic System no battery in terms of maximum load study, with the exception of the remaining power storage system, Economics study of this system is costs $ 750 and earning $153 per year, this system can benefit consumers 88%, equivalent to $ 659 according to an 18-year study.
