The University of Arizona is developing a <1kW sized solar thermal mechanical pumping system that appears to have great potential for meeting small pumping requirements (~4000 liters/day with 10 m lift) in locations with adequate solar resource. This solar pumping system is believed to be applicable to many remote domestic and irrigation applications without access to electricity, relying on diesel power and/or having insufficient wind for pumping and to be a cost competitive, locally manufacturable alternative to photovoltaics. The system consists of solar collector, single piston diaphragm engine, custom valving, condenser and return pump. The piston actuates a lever connected to a lift pump. Testing in Oman is scheduled for Spring, 2003.
