Su arıtma ve pompalama sistemi için güneş enerji kullanımının teknik ve ekonomik analizi

this study presents a technical and economical analysis of an independent pumping and treating water simulated system that has been arranged by using PVsyst software. This system which depends upon the combination of the well's water and the solar panel's energy, is used to activate a purification system that uses the Reverse Osmosis system. The study tries to solve the problem of demand for usable water for daily usage in the facility, which is about 9 cubic meters per day in the place, which is located in Basra city in the southern region of Iraq but away from the city center. This thesis consists of two sections, circuit A (solar pumping section) and Circuit B (reverse osmosis section). Circuit A; with the electric energy obtained from solar panels, water is obtained directly from the well and sent to the tank without the need for energy storage, however circuit B, the energy obtained from PV panels is stored by batteries and operated at certain times of the day. The tests were on three different wells with different static levels( 10, 20, 30 m) with different tilt angles of PV panels (15, 30, 45˚). After making the simulation processes for each well it shows that 10 m static level and 45 deg system efficiency and return of investment is 75.2% and 523.5% in a row well, However, 20 m static level well and 45 deg system efficiency is 65.9 % and return of investment is 496.9 %, at the same time 30 m static level with 45 deg system efficiency 79 % but the return of investment 470 %.
