Scenario of Solar Photovoltaic Water Pumping System
2024
The need for agricultural and community water sources to be pumped is impacted by the high cost of diesel and the absence of electricity, particularly in rural areas. Thus, one alternative to conventional electricity and diesel-based pumping systems might be the use of solar energy for water pumping. Solar energy could therefore be a viable water pumping alternative to traditional electricity and diesel-based pumping systems. This review gives a glimpse of information on solar water pumping technology, and the research gaps for its wider adoption. The matching of characteristics between solar photovoltaic modules, controller, motor and pump is the great task to obtain optimum overall efficiency or solar pump efficiency.
Design and Development of a Photovoltaic Water Pumping
2010
The aim of the paper is to present the influence of the solar radiation variation on the performances of a stand alone photovoltaic pumping system which consists of photovoltaic generator, dc–ac inverter, an immersed group motor-pump and control box. The system was installed at the faculty of Engineering and Technology, University of Gezira. The incorporation of photovoltaic systems in water pumping applications is thought to be one of the most popular and ideal uses of solar energy exploitation, especially under the common allegation of coincidence between solar insolation and water demand. From the obtained results, we will show that the decrease of the solar radiation degrades performance (solar generator voltage, inverter voltage and the flow rate) of the photovoltaic pumping system. The total performance of the pump is mainly dependent on the specification of the equipment used. Key words: solar radiation, photovoltaic pump, photovoltaic generator, solar insolation, dc-ac inverter
Research and current status of the solar photovoltaic water pumping system -A review
Water and energy are the key drivers of agricultural production while the world is facing severe energy and water crisis. Increasing crop production per unit area for the increasing population of the world is dire need of time. Thus, sustainable approaches are required to ensure food security and energy security. One of the sustainable development approach is solar photovoltaic water pumping system (SPVWPS). It is a promising alternative to the conventional pumping systems and a cost-effective application especially in remote off-grid areas of developing countries. In recent years, through continuous improvement, the photovoltaic pump system has been widely used in agricultural, industrial, and domestic sectors. Present paper intends to review and summarize the recent research and development performed in SPVWPS. The study focuses on components of the photovoltaic pump system, factors affecting system efficiency, performance assessment, optimization of the system, and possibility of combination with other green technologies. An update on the research and current situation of SPVWPS is presented. SPVWPS is found to be feasible in comparison to the conventional pumping systems. Application of PV pumping in different regions of the world are also discussed. This paper aims to provide a broad outlook on SPVWPS for the researchers, engineers, manufacturers, and policy makers.
Techno-economical study of solar water pumping system: optimum design, evaluation, and comparison
Solar water pumping systems are fundamental entities for water transmission and storage purposes whether it is has been used in irrigation or residential applications. The use of photovoltaic (PV) panels to support the electrical requirements of these pumping systems has been executed globally for a long time. However, introducing optimization sizing techniques to such systems can benefit the end-user by saving money, energy, and time. This paper proposed solar water pumping systems optimum design for Oman. The design, and evaluation have been carried out through intuitive, and numerical methods. Based on hourly meteorological data, the simulation used both HOMER software and numerical method using MATLAB code to find the optimum design. The selected location ambient temperature variance from 12.8°C to 44.5°C over the year and maximum insolation is 7.45 kWh/m 2 /day, respectively. The simulation results found the average energy generated, annual yield factor, and a capacity factor of the proposed system is 2.9 kWh, 2016.66 kWh/kWp, and 22.97%, respectively, for a 0.81 kW water pump, which is encouraging compared with similar studied systems. The capital cost of the system is worth it, and the cost of energy has compared with other systems in the literature. The comparison shows the cost of energy to be in favor of the MATLAB simulation results with around 0.24 USD/kWh. The results show successful operation and performance parameters, along with cost evaluation, which proves that PV water pumping systems are promising in Oman.
Solar photovoltaic water pumping system approach for electricity generation and irrigation: Review
Diagnostyka
Solar energy for water pumping is a possible alternative to conventional electricity and diesel-based pumping systems, particularly given the current electricity shortage and the high cost of diesel. The literature survey includes a comparison between previous studies of pumping systems using photovoltaic cells, and the extent of the influence of external factors such as radiation intensity and temperature on the efficiency of the system. Additionally, the use of water storage to generate electrical energy through potential energy by means of hydraulic generators and the effect of the amount of flow and height on the amount of energy generated, as well as the types of hydraulic generators are discussed in this paper. Nowadays, solar power is a major contributor to the world's electrical energy supply, either by generating electrical energy directly from solar cells or through water storage, which will be covered in this review. When compared to electricity or diesel-powered systems, solar water pumping is more cost-effective for irrigation and water supply in rural, urban, and remote areas. This paper also highlights the challenges that must be overcome to develop high-quality, long-lasting solar power technology for future use.
Review on Solar Photovoltaic Water Pumping System
— Agricultural technology is changing rapidly. Farm machinery, farm building and production facilities are constantly being improved. Agricultural applications suitable for photovoltaic (PV) solutions are numerous. These applications are a mix of individual installations and systems installed by utility companies when they have found that a PV solution is the best solution for remote agricultural need such as water pumping for crops or livestock. A solar powered water pumping system is made up of two basic components. These are PV panels and pumps. The smallest element of a PV panel is the solar cell. Each solar cell has two or more specially prepared layers of semiconductor material that produce direct current (DC) electricity when exposed to light. This DC current is collected by the wiring in the panel. It is then supplied either to a DC pump, which in turn pumps water whenever the sunshine's or stored in batteries for later use by the pump. Solar Photovoltaic water pumping system (SPVWPS) has been a promising area of research form more than 50 years. SPVWPS consists of different components and parts associated with different fields of engineering like mechanical, electrical, electronics, computer, control and civil engineering. The interdisciplinary nature of the system attracted there searchers, in the past, from all these fields of engineering and has been contributed by them to make the system more efficient and cost-effective to meet water-pumping needs of human, livestock and irrigation.

KIU Journal of Science, Engineering and Technology
This study examines the integration of grid and solar energy resources in remote water pumping systems to improve performance and reliability. The feasibility of a hybrid solar PV-grid system is investigated to assess its technical and financial performance compared to standalone solar PV or grid systems. A unique aspect of this hybrid system is the utilization of a water storage tank instead of energy storage for solar PV conversion. The system comprises a PV array, inverter, AC motor, submersible pump, storage tank, grid supply, and control systems. The paper presents a cost-effectiveness analysis using Net Present Value (NPV), Levelized Cost of Energy (LCOE), and Internal Rate of Return (IRR) to economically evaluate the power supply for pumping systems in community areas. The study focuses on two energy supply systems: solar photovoltaic systems and the grid network. A case study is conducted in the western region of Uganda, where the pumping systems are designed to provide wate...
Optimum Design and Evaluation of Solar Water Pumping System for Rural Areas
International Journal of Renewable Energy Research, 2017
Sultanate of Oman like the rest of GCC countries is a fossil-fuel-rich country that highly depends on the production of natural gas which exists in massive amounts of its land, which makes electricity generation through natural gas a cheap solution. However, power transmission to rural areas costs the government massive amounts of money. The need of electricity for rural areas, especially for water pumping systems, is crucial to farmers. One solution is to use diesel generators for water pumping; however this solution is costly over the long run and not environmentally friendly. This paper studies the use of PV-powered water pumping system instead and shows techno-economic and environmental studies comparing both PV and Diesel pumping solutions. The PVWPS showed to be more cost-effective for Oman than the diesel generator over the lifetime of the system and having 0 carbon emissions, making it the obvious choice for such issue. The optimum COE found for the PV-powered pumping system...

Energy is one of the key factors for development of the country, and it can gain from different sources, but some of these sources are not environmentally friend, expensive and difficult to transport; like fossil fuel. Using solar energy is the best option to solve this problem. The objective of this study is Simulation of Photovoltaic water pumping system for small scale irrigation and rural electrification by using PVsyst soft-wares. The people living in grid connected system use electric powered pumping or diesel generator for pumping water, but people living in rural off-grid area can't get electric powered pump. Therefore this problem would be solved when they use solar photovoltaic pumping. In this work Madhicho is study area of this study is done at 9.14° latitude and 40.75° longitude. In this study analysis of PV water pump by using PVsyst or RET Screen Expert. Most of the time the major problem of solar PV water pumping system technology has been the wastage of energy in idle manner without using energy which is only used for target of specific purpose and time but in this research when no need of irrigation, the systems require batteries to store the sun's energy for use during summer periods. Total quantity of water required for irrigation is 145125liter per day the Pump power that can able to pump water from well to storage tank is 20kw the number of PV module to satisfy pump power is 55 and total energy produced from solar panel 22kw. Solar PV water pumping system can be reliably used at where absence of continuous local grid available where as solar PV and battery storage need is critical
