Abstract

A solar-PV powered helical pump was tested at three different pumping depths (50, 75, and 100 meters) and two different solar-PV array power ratings (480 and 640 Watts). This testing began in Feb, 2004 and has been performed continuously since that time at the USDA-ARS Laboratory near Bushland, TX. So far this solar-PV water pumping system has performed very well and reliably and it should be a good economical system for many livestock watering applications. For all pumping depth/PV power ratings tested, a relatively high total system efficiency of 5 to 7% was achieved and a low cut-in irradiance of 100 to 300 W/m2 was demonstrated. For Bushland, TX (annual average of 5.5 to 6 kWh/m2/day at latitude inclination) the amount of beef cattle that could be watered ranged from 60 cattle (100 m pumping depth/480 W PV array) to 150 cattle (50 m pumping depth/640 W PV array).
