Groundwater abstraction to meet irrigation demand is becoming a costly affair due to significant energy poverty in terms of electricity deficits and substantial increase in the cost of fossil fuel. Under this scenario, solar energy could be the most viable and sustainable option given its potential over India's geographical location. The dominance of small farms, policy frameworks, and financing schemes to increase solar energy use; many Indian states are offering heavy subsidies, even up to 90%, on small-capacity solar pumps to benefit smallholders. One of the popular and subsidized systems is a 3.0 horsepower solar water pumping system among the system categories. This paper presents the status of smallholders' irrigation, photovoltaic technology, and its possible application, and performance of a 3.0 horsepower solar pumping system evaluated under the incidence solar radiation of 3.4-6.4 kWh/m 2 /day and the prevailing groundwater depth regime in Eastern region of India. This could help the smallholders to plan for crops and cropping sequences under the command area of this pump for more benefits.

India′s smallholder agriculture boomed with supplemental irrigation made possible by diesel and electric pumps. Nevertheless, the smallholders' irrigation is under siege from an energy squeeze with deteriorating farm power supply and manifold increase in diesel prices. This energy squeeze undermines the adoption of broad range precision irrigation technologies and profitable productivity of small holdings. However, the use of solar energy particularly in groundwater pumping and use of pressured irrigation could improve energy access, reduce fossil fuels 2 consumptions, as average incident solar radiation over India's geographical area is of 4-7 kWh/m / day with 250-300 clear sunshine days/year. To promote solar energy use under the prevailing solar radiation conditions and depth to water level scenario of groundwater a suitable groundwater pumping system model is required to fulfil the irrigation needs. This paper describes a solar photovoltaic groundwater pumping model suitable for small farm irrigation ether by traditional methods of irrigations or by pressured method, as it generates pressure heads of 98-147kPa when 2 incident solar radiation ranged from 400-800W/m , the solar radiation condition which prevails over its geographical area between 9.00-14.00 hrs round the year.

Technical and Economic Feasibility of Solar Irrigation Pumping System: A Review
Knowledge-Based Engineering and Sciences, 2020
Climate change has become a major constraint to the development of rain-fed agriculture due to the decline of rainfall. Therefore, irrigated agriculture is an alternative allowing farmers to have more access to water in order to meet crop water requirements. However, irrigated agriculture faces a major constraint related to the accessibility of energy sources used in pumping water. In general, the most common energy sources used in pumping water for irrigation are fuel and electricity. Nevertheless, they are very expensive, are not always accessible particularly in rural areas in Africa and have a negative impact on the environment; hence the need to find alternatives to solve this problem. This review focuses on the technical and economic feasibility of solar irrigation pumps and the impact of their use on the environment. Several aspects related to solar pumping have been discussed, namely the components of the solar pumping system, the energy source used, the principle of operati...
Optimal Sizing of Solar Water Pumping System for Small Scale Irrigation: Case Study of Dangila
International Journal of Sustainable and Green Energy, 2014
The diesel driven water pumping systems have a great impact on irrigation in remote areas around the world. However the gradual increase of fuel prices worldwide and high maintenance cost discourages the utilization of the technology. Therefore, it is important to think of an alternative energy source for such application. The optimal sizing of this PV water pumping provides theoretical studies of photovoltaics and modelling of electric power requirement for powering pump to irrigate crops as an alternative to diesel technology. The analysis employs determining the optimum tilt angle of solar panel which can collect the maximum solar energy when irrigation water demand could be higher based on seasonal Variation. The irrigation requirement has been determined by combining climate inputs, hydrology, crop type and developing stage, soil type, moisture and irrigation method etc. at each time stage of irrigation period. The power requirement has been analysed using dynamic programming by relating hydraulic load with the solar radiation energy from the solar panel for each decadal irrigation period. The maximum power has been minimized so as to select the power which can satisfy all irrigation periods with reduced cost of PV system. Furthermore Pumps (Centrifugal surfaces) with high discharge and low heads are selected to minimize water cost for such application as surface water sources from rivers and ponds are mostly applicable for irrigation in Ethiopia.

Water is an essential part for all living creatures. There is no water in other planets so there is no life. But irony is when someone lives in that area which is surrounded by worlds one of the biggest water system but has to walk up and down in hills for fetching water. In this study, a water pumping system is introduced for combating this situation. Deployment of solar PV based water pumping is used because it is pollutant free and the price of clean energy sources are decreasing day be day. Solar system is best alternative to age old conventional systems which were costly and they emits greenhouse gases.

Technical and Economic Feasibility of Solar Pump Irrigations for Eco-friendly Environment
Procedia Engineering, 2015
This paper presents the technical and economic suitability of solar pump irrigations of rice and no-rice crops. Four submersible solar pumps (1050 W p) were installed in different locations of Bangladesh for irrigating rice, wheat and vegetables. The solar pump was used for drip irrigation and furrow irrigation for cultivation of brinjal and tomato during 2010-13. Water savings by drip irrigation over furrow irrigation for brinjal and tomato were 53.25% and 56.16%, respectively. For cultivation of wheat about 430 mm water was required and the yield was 3.00 t/ha. Water required for boro rice cultivation in Magura was 1024 mm and in Barisal it was 1481 mm. Cultivations of solar irrigated wheat (BCR 2.31), tomato (BCR 2.22) and brinjal (BCR 2.34) were economically profitable but boro rice was not economically profitable (BCR 0.31). Diesel engine operated irrigation pump emits carbon dioxide but solar pump is an environment friendly irrigation technology.

Adequate irrigation of farm plants irrespective of the amount of rainfall due to seasonal variations is essential for a successful large scale farming system. In addition, the challenges of erratic electricity supply has made alternative power source for effective irrigation important. Consequently, this study designed and simulated a solar powered water pumping system for irrigation purposes. A hectare of pepper plantation was adopted as a case study in Kaduna, Nigeria. The study was carried out using a software package called PVSYST version 5.5. The result of the study predicted a pumping efficiency of 65.8%. Except for the months of April, May, June, July and August which usually fall within the rainy season and water is expected to be sufficient, the system predicted adequate water supply for pepper irrigation in other months where dearth of water is always experienced. It was concluded that: irrigation farming using solar powered water pumping system is feasible in Kaduna.
