water is an essential resource for agriculture and the majority of land is irrigated through borewells or wells.The power requirement for an irrigation pump motor is fed by the on-grid power supply but the availability of electricity in rural areas is still questionable.With rising concerns about global warming and the rise in carbon footprints,it is necessary to choose clean and green energy,thereby attaining self-sustainable life.India receives yearly a mean solar irradiation of 6.5 kWh/m^(2)day.Hence,a solar photovoltaic-water-pumping system(SPV-WPS)is a suitable alternative to grid energy;thereby,the farmers would generate electricity through the solar photovoltaic system and become self-sufficient in their energy needs.In this paper,two different agricultural fields in Tamil Nadu,India that deploy flood irrigation and drip irrigation are taken as a case study.The paper discusses the concerns on the use of grid power and their carbon footprint,design and simulation of 4-and 5.5-kW SPV-WPSs using PVsyst 7.1.1,and the advantages of using SPV-WPSs and life-cycle cost analysis on different use cases.The Government of India has introduced a special scheme to promote the installation of SPV-WPSs by offering attractive incentives through PM-Kisan Urja Suraksha evam Utthaan Mahabhiyan(KUSUM)yojana.The results of the case study show that with the use of SPV-WPSs,either with or without subsidy,the farmer could gain a minimum of 250%on the investment with a project lifetime of 25 years.

Utilization of solar Energy in Irrigation Systems in Bangladesh

The demand for water pumping in urban water supply and irrigation in Bangladesh is significantly influenced by electricity deficits and high diesel costs. To address these challenges, the adoption of solar power for water pumping emerges as a viable alternative to traditional systems reliant on grid power and diesel. In recent years, there has been a growing emphasis on clean and renewable energies, aligning with the environmental and economic priorities of Bangladesh. The agricultural sector, serving as the backbone of the country’s economy, witnesses an escalating demand for water as the population increases. The extraction and transfer of water for agricultural and drinking purposes translate to high-energy consumption. Leveraging the abundant and essentially free solar energy, particularly during the crop growth periods when irrigation is crucial, presents an optimal solution. This study underscores the underutilization of this vital resource in Bangladesh and advocates for the widespread implementation of solar energy conversion programs, specifically in photovoltaic pumping systems. By comparing these systems with conventional diesel pumps, this paper aims to inspire policymakers, statesmen, and industry professionals to integrate green energy into the water sector. The envisioned outcome is a strategic shift towards sustainable development, with a focus on harnessing solar power to pump water for villages and agriculture, thus contributing to economic and environmental sustainability.
