Solar Power Technology for Supplying Safe Drinking Water
Published in Joseph A. Cotruvo, Gunther F. Craun, Nancy Hearne, Providing Safe Drinking Water in Small Systems, 2019
PV-direct water pumping systems pump the water only when there is sufficient sunlight to start the pump. PV-direct systems are generally preferred over PV-battery systems. Tracking systems are used to face the PV modules toward the east in the morning and follow the sun during the day until the modules face west in the afternoon. With tracking, the water pump can start earlier in the morning and run later in the afternoon, thus pumping more water per day. The cost of the tracking system is balanced against the cost of additional PV modules that are fixed with respect to the sun. In some extremely windy locations, a fixed PV system may be preferred or a wind-powered system may be selected.

The other solution for water pumping and irrigation is the wind pumping system with electric energy storage (Fig. 13.6). This system is similar to the solar photovoltaic (PV) pump described in Volume 2 of this book series (Chapter 12). The electric energy produced by the wind generator is stored in batteries. The process of charging is regulated by a controller, which ensures the optimal operation conditions of the DC generator at different wind speeds.

The electrical energy need for pumping water (wh/day) depends on the ratings of the pump to be selected among the commercially available ones and must be well sized to match the local solar regime of the location. However, selection of pumps in a solar powered water pumping project depends on several factors including: availability of water supply, size of the available water storage system depending on the water needs, total dynamic head, diameter of well and the population size demand. In this paper, submersible pumps are used in order to have a properly sized pumping system and it is assumed that the pump will be in operation only during the peak sunshine hours. To determine the best efficient pump in the market, the system total dynamic head () must be determined and matched with the data sheets of the commercially available ones. The pump whose characteristics best matches the total system dynamic head will be selected. The system dynamic head can be evaluated as
