The integration of Variable Frequency Drives (VFDs) into solar-powered water pumps (SWPs) offers a potential leap towards eco-friendliness and cost-efficiency, particularly in the agricultural sector. Despite the known benefits of VFDs in enhancing traditional pump efficiency, their impact on SWPs remains underexplored. This systematic review meticulously investigates the role of VFDs within SWPs, focusing on their reliability, performance enhancements, and economic impact. Utilizing the PRISMA method, the review distilled insights from 898 records, ultimately scrutinizing 29 studies that discuss the effectiveness and overall evaluation of VFDs in SWPs, with a subset of 8 studies endorsing their high efficacy. The findings aim to consolidate current knowledge, support stakeholder decisions, and carve a path for subsequent research endeavors. This evaluation sheds light on the tangible advantages of VFDs in solar-powered setups, marking a significant step in sustainable energy application and reducing carbon footprints in agricultural practices. The evidence underscores the transformative potential of VFDs in SWPs and calls for increased attention to this synergy to harness the full spectrum of environmental and economic benefits.
