PV-Based Water Pumping System-A Comprehensive Review

摘要

Pumping system based on photovoltaic energy is a proven alternative for farmers, who are still not connected with the main grid. In literature, over the past two decades, a considerable, great deal of research has been carried out in this area. Energy efficient solutions have been developed and proposed in the literature, addressing many practical issues of such systems, like mismatching/shading, variations in irradiance level, load mismatch, motor-pump efficiency, pumping system maintenance, maintenance and initial cost of installation. This paper gives a comprehensive review on the water pumping system solely based on the PV technology which is easy to understand the present scenario, the purpose and understand the gaps in research that are limiting the wide applications or implementations of such PV-based irrigation systems. During the literature survey, it was realized that many critical and practical real-field problems like diminishing water levels, low PV power availability during early morning and late evening hours, low ROI, high maintenance cost, optimized system sizing, selection of particular configuration/topology and high installation cost still need attention. It was found that either these problems are not addressed or solutions to these problems are not available in implementable form or their feasibility analysis is still required. This paper would be helpful to understand the status of developments in water pumping system solely based on the technology of PV and will give a clear vision to readers for future work.
