This paper discusses methods and techniques for transporting and desalting groundwater supplies using the renewable energy derived from solar photovoltaic systems. The reliability of this type of equipment is emphasized, which operates in remote areas far from other power supplies and maintenance facilities. Until relatively recently, the cost of photovoltaic arrays in remote areas, compared with thermal methods of desalination, precluded their use. But recent development in photovoltaic technology have changed this. The use of brushless dc motors directly coupled to the PV array eliminates the cost of inverter power conditioning required for ac induction motors. The PV/brushless dc motor configuration yields a particularly good technical fit for pumping and desalting groundwater in the Australian Outback.
