Grid Connected Solar PV System for Green House Desalination Plant

This study looks into the design, performance analysis, and optimization of a solar PV system to power a reverse osmosis desalination plant (RODP). The main goal is to compare the proposed grid connected solar PV to the conventional utility grid in terms of technical (balance supply and demand – meet the desalination plant's daily, monthly, and yearly electrical load), economic (cost of electricity COE), and environmental (CO

emission reductions) performance. This study employed modeling and simulation analyses to develop and assess the performance of a grid connected solar PV system for the RODP in Sharjah. The RODP's daily electricity load is 125.2 kWh/day (high pressure, feed, and dosing pumps). The results demonstrate that 82.7 percent of the energy produced by the grid-connected solar PV system is produced by the solar PV system, while 17.3 percent is acquired from the grid. All of the RODP's electrical load was met on a daily, monthly, and annual basis (no capacity shortfall), and 11.3 percent of the total electricity generated by the solar PV system was sold back to the grid. The price of power fell from ＄0.12 per kWh (grid purchase price) to ＄0.0856 per kWh (renewable power system). With the grid connected solar PV system, the renewables fractions for power generation grew from 0 to 81.2 percent. The grid connected solar PV system resulted in net emissions reductions of 78.8%, 89.6%, and 56.6 percent for CO
