The lack of electricity; high diesel prices affect Community water supply and irrigation pumping requirements and recent environmental issues coupled with diesel engines demand for a feasible alternative power source for irrigation water pumping. Solar power for water pumping is a good option and attractive choice for conventional diesel-based pumping systems. These systems have been introduced for various applications in many remote areas, ranging from grid extension and community water management to irrigation for agriculture and water supplies for livestock. The aim of this study is to evaluate technical, economic and environmental analysis of solar water pumping systems performance and compare them with convention diesel pumping systems to meet water requirements in irrigation, livestock watering, and neighborhood water supply fields. Recognition system design and selecting suitable design parameters is essential in order to achieve consistent and economical performance of any system. In order to design a solar water pumping system, it is necessary to collect information about the system components and local location climate data. Here , the maximum pumping power required of the solar PV water pumping system, which was determined for 121 m3/hr supply is 443 kW peak (8477 kWh/day) of inhabits residential, live stock and crops irrigation of agriculture remote site without grid power located in El Gharaq, Etsa Region, Fayoum City, Egypt. In parallel, a battery bank has been used as a backup during days of autonomy to increase the system stability. The system design investigates: diesel system, off-grid PV/battery system and compares with PV/Grid system extension power grid. The system model approach defines optimum system configurations with minimal cost of the photovoltaic modules, optimum battery bank size, and volume of storage tank. The optimization model takes into account the average monthly solar radiation, the fulfilling of the water required and the amount of autonomous days needed. The proposed sizing methodology is then performed to check the reliability of this proposed optimization method using commercial optimization software of HOMER 3.13.8, with the key parameters of minimum NPC and COE that shows better results using the system method proposed. It also estimates the pumping power capacity using calculations and equations. The results illustrated that the optimal configurations of this proposed system are 2.57 kW of PV and 2.11 kW converter of on-grid system while 3.83 kW PV and 1.71 kW converter and 10 units of 12 V batteries for PV/battery off-grid system and 3.10 kW PV for diesel system. Also, it was found that the net present cost of solar water pumping system for on-grid mode is equal 3 times of the PV-battery off-grid system and 4 times of convention diesel system net present costs. The cost of energy of solar water pumping system is 0.07 $/kWh for on-grid system while 0.332 $/kWh for PV-battery off-grid system and 0.434 $/kWh for diesel system. With a unit of 0.05 cent/m3, the system with the specified design pumps an average hourly water volume of about 121.4 m3 over one year. The return on investment is found to be 4–6 years for solar water pumping systems. Moreover, from an environmental point of view, the results showed that CO2 output for the on-grid solar water pumping system during the project's lifetime is 6 times lower than that for the standard diesel system. Through sensitivity analysis; energy costs increase by increasing the water storage tank's maximum capacity. Also, when discount rate is increasing; the NPC and COE are also increasing. The Pumping Power capacity is also estimated for this water pumping system and it is found around 10 HP. The results indicate that extension PV on-grid pumping system is the optimum solution for the selected site. Latest Egyptian Photovoltaic Pumping Incentives and policy proposals to encourage solar water pumping in developing countries are also mentioned. It also defines possible areas for investigative follow-up.

This study investigates the current status of photovoltaic water pumping systems (PVWPSs) in Iran, a country endowed with significant solar irradiation potential, notably in its southern and central regions. Despite this potential, there is a scarcity of comprehensive studies on solar water pumping systems within the country. This purpose of this study is to conduct a thorough review of the existing literature to assess the state of solar water pumping in Iran. The adoption of PVWPS across various provinces demonstrates the system's versatility, proving effective in both highly sunny and less irradiated regions. Iran's widespread utilization of PVWPS is attributed to its ample irradiations, even in its northern areas, which possess lower solar irradiance levels. There are limited comprehensive studies encompassing technical, economic, environmental, and social aspects of solar PV water pumping projects in Iran. Most of the research has been conducted during the last few years, indicating an increased recognition of the possible advantages of this technology. Finally, this review provides valuable insights for researchers and farmers, showcasing the benefits of solar PVWPS. It sets the stage for further innovation and implementation in the country's agricultural landscape, emphasizing the need for continued exploration and adoption of this sustainable approach.

“…A study of the PV pumping system Sontake et al [3] (considering a 10 feddan irrigation system of nominal power of 7 KW p and a life time cycle of 20 years for the pv solar system and 10 years for the diesel pumping system) proves that PV pumping system saves more than 30% cost less than diesel generator pumping system cost. Parvaresh Rizi et al [4,5] presented financial comparative study of solar and regular irrigation pumps which shows the carbon dioxide emission reduction and cost effectiveness of solar pumping systems., On grid systems is another example of solar energy utilization importance.

Accurate PV system simulators are implemented with expensive software platforms using paid irradiance data. The main purpose of this paper is to develop and validate a PV system simulator, beginning with a solar cell parameter extraction model, then test and validate long-term Irradiance data using free online source (Typical Meteorological Year TMY in (PVGIS) European website), and finally building full solar generator simulator to run in working real conditions. Comparing results with Accurate Paid PV simulators (which use the Muneer model) showed good accuracy of the proposed simulator. Work flow starts with the Irradiance model's data processing, then solar cell 5 parameters model data processing (to extract cell parameters), and finally full system simulator. MATLAB coding programs in real working conditions are used for simulation. Results of solar cell parameter extraction show 99.6% to 99.99% matching with data sheet and cell performance under standard test conditions. System model simulation output shows 8% less yearly generated energy compared to the PVGIS 2022 long-term simulation (hourly basis (one-year time)). This is due to incident energy variations (between the years 2016 and 2022) of 4.02%. The novelty of the algorithm is the methodology, as it tests irradiance data on an hourly basis and validates results for a whole continuous year. Also, the 5-parameter solar cell model is used to be validated in long term analysis, not only STC conditions and could be applied on any PV solar cell. The algorithm and block diagram used are scalable, modular, and interchangeable with similar models to be tested. This simulator could test several methods and models in solar pv technology.
