promisinglyhigh; reaching about 5.8 kW h/m2/day, which almost equals the best month radiation of wide areas in Europe and Asia. Accordingly, it can be concluded that using solar energy in the south of Jordan is very practically and theoretically applicable, and is even preferable to other conventional types of energy. A complete methodology for designing a PV solar system to operate underground water pumping for the selected well-34 was carried out. This includes the solar radiation calculations on tilted and horizontal surfaces, then sizing and selection of the PV system components which includes, the PV panels and their best orientation, the inverter, charge controllers, batteries and their ratings including cable sizing. Two methods were considered for the PV system design, these two methods were: Worst Month Method Analysis and the Peak Sun Hours Analysis (PSH). The design process was based on the worst month of the year which was December. Beyond the design conditions of the worst month, 38% of the total PV panels would not be used, as the other 62% of panels will be producing enough energy to power the submersible pump. Furthermore, the effect of dust accumulation on the PV panels was studied and analyzed. Beyond the design conditions of the worst month (December), extra energy can be produced by the PV during the rest of the year time, which can be used for many purposes. Dust accumulation problem on PV surfaces should be accounted for, either by cleaning process or as a 5% power loss factor. PV solar energy has a great economical viability over other conventional types of energy such as grid and gen set in respect of life cycle costing method LCC for the selected well-34.
