“…The main object in designing a PV pumping system (PVPS) is that the required pumping power should be generated by a minimum number of PV panels in order to improve the cost effectiveness [13,14]. The DC-PVPS considered here has been previously optimized for the design site by using the long-term measured weather data [9].…”

“…According to the majority of the authors (Firatoglu and Yesilata 2004;Purohit 2007;Short and Oldach 2003), the financial viability of solar PV energy with respect to the other conventional options, electric or DG, for the pumping of water is the principal barrier which slows down its broad adoption.…”

For estimating the performance of a photovoltaic (PV) water pumping system without battery storage, a simple algorithm has been developed. This simulation program uses the hourly global solar radiation, the hourly ambient temperature and the hourly wind speed as the input, moreover the characteristics of region (latitude, longitude, ground albedo) and characteristics of PV water pumping system (orientation, inclination, nominal PV module efficiency, NOCT, PV array area, PV temperature coefficient, miscellaneous power conditioning losses, miscellaneous PV array losses, temperature of reference, moto-pump efficiency and inverter efficiency). This work allows evaluating the economic interest of a remote PV water pumping systems in the desert of Southern Tunisia, which will have to satisfy an average daily volume of 45 m 3 throughout the year compared to another very widespread energy system in the area, the diesel genset (DG), by using the method of the life-cycle cost (LCC). The cost per m 3 of water was calculated for this system. It is found that the LCC for PV system is 0.500 TND/m 3 and the LCC DG is 0.837 TND/m 3 . The present study indicates economic viability of PV water pumping systems in the desert of Tunisia.

“…Photovoltaic pumping systems (pvps) have been employed in some projects, and under the right conditions can provide a reliable and cost-effective means of lifting water. At present, the pvps in use tend to consist of relatively highly engineered components for both the power conditioning electronics, which interface the solar array with the rest of the system and the motor/pump unit [1,2]. Motors that are in use are typical rotating machines, smaller installations tend to use direct current (dc) and larger installations use alternating current (ac).…”

A new positive displacement pump operating with a simple linear actuator as the prime mover has been designed, built, and evaluated. The aim is to develop a pump that uses a photovoltaic (pv) power source and is suited to supplying water in rural areas of low-income countries. Previous schemes to raise water from boreholes with a pv power source have used sophisticated technology, which can be a significant step beyond the previous experience of the communities being served. A configuration of linear actuator and pump has been chosen by seeking the simplest mechanism from the point of view of both operation and manufacture. Finite-element analysis of the electromagnetic properties of the actuator is shown to be the best way to proceed in the design process. A very simple design with an actuator operating in a normal force configuration is shown to function effectively.
