Abstract <p>This study assessed the feasibility of performing a technical and economic analysis of solar-powered irrigation systems (SPIS), electric-powered irrigation systems (EPIS), and diesel-powered irrigation systems (DPIS) for irrigating crops in different locations in Bangladesh. Twenty-two samples (twelve for the SPIS, two for the SPIS with household electrical-grid supply, four for the EPIS, and four for the DPIS) were randomly selected to assess and compare the performance of the different irrigation systems. The capacity of the solar panel varied from 4.2 to 14 kW. The study also identified the constraints of using a SPIS. Compared with SPIS and DPIS, the gross margin of various crops was greater for EPIS. On the other hand, a lower gross margin from the DPIS was obtained because there was less gross irrigated area for the production of crops. Among the case studies, the benefit-cost ratios (BCR) were 0.10 and 0.05 for SPIS and SPIS with household electrical-grid supply systems, respectively, whereas the internal rate of return (IRR) and net present value (NPV) were negative, which indicates that these irrigation systems were not economically profitable at this time. The power sources of DPIS were not found to be profitable. The DPIS induces equivalent CO₂ emissions of approximately 6% of the total agricultural land, which the SPIS can substitute. The BCR, IRR, and NPV were approximately 1.39, 44%, and USD 2369, and NPV were approximately 1.39, 44%, and USD2369 in EPIS compared with other power sources. This indicates that an EPIS with a centrifugal pump is economically viable and profitable compared with solar and diesel-powered irrigation systems for the sustainability of crop production in the current era of a changing climate.</p>
