The use of this photo-irrigation system will be able to contribute to the socioeconomic development. It is the proposed solution for the energy crisis for the Indian farmers. This system conserves electricity by reducing the usage of grid power and easy to implement and environment friendly solution for irrigating fields.

Optimal Solar Water Pumping System for Small Scale Irrigation : A Case Study on Economical Sizing for Dangila Area of Ethiopia

2017

There is a great impact of diesel driven water pumping systems on irrigation, in remote areas around the world. However the gradual increase of fuel price worldwide has a serious effect on this system, that discourages the utilization of such technology. As an alternate, it is expected to deal with the economical solar water pumping system for small scale irrigation applications. This paper deals with the design of this PV water pumping, which provides the theoretical studies of photovoltaic and the analysis of electric power requirement for powering pumps for irrigation. The analysis employs determining the optimum tilt angle of solar panel which can collect the maximum solar energy, when irrigation demand could be higher based on seasonal variation. The irrigation requirement has been determined and the maximum power has been minimized so as to select the power which can satisfy all irrigation periods with reduced cost of PV system.

Design and Simulation of Solar Powered Water Pumping System for Irrigation Purpose in Kaduna, Nigeria

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.

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.

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.

Solar-based groundwater pumping for irrigation: Sustainability, policies, and limitations ARTICLE INFO

Energy Policy, 2017

The increasing demand for solar-powered irrigation systems in agriculture has spurred a race for projects as it potentially offers a cost-effective and sustainable energy solution to off-grid farmers while helping food production and sustaining livelihoods. As a result, countries such as Morocco and Yemen have been promoting this technology for farmers and national plans with variable finance and subsidy schemes like in India have been put forward. By focusing on the application of solar photovoltaic (PV) pumping systems in groundwater-fed agriculture , this paper highlights the need to further study the impacts, opportunities and limitations of this technology within the Water-Energy-Food (WEF) nexus. It shows how most policies and projects promoting solar-based groundwater pumping for irrigation through subsidies and other incentives overlook the real financial and economic costs of this solution as well as the availability of water resources and the potential negative impacts on the environment caused by groundwater over-abstraction. There is a need to monitor groundwater abstraction, targeting subsidies and improving the knowledge and monitoring of resource use. Failing to address these issues could lead to further groundwater depletion, which could threaten the sustainability of this technology and dependent livelihoods in the future.
