Energy alternatives for water pumping in rural areas: Using a case study approach

This paper reviews energy alternatives for groundwater pumping in remote, rural areas which are not grid connected or where grid extension costs are prohibitively high. The applicability of photovoltaic (PV) pumping under certain conditions is discussed, using examples of in-service fieldwork results, and experimental results of a laboratory PV pumping rig with remote monitoring capabilities using telemetry. The outcome of the survey and analysis shows that PV pumping can be competitive with other technologies under specific head and flow conditions, although the socio‐institutional implementation strategies are crucial to the techno‐economic success of actual pumping schemes.
