Solar-Powered Livestock Watering Systems
Because of falling prices, long life, and low maintenance requirements, solar is rapidly becoming the first choice for pumping water in remote locations. This publication gives an introduction to solar-powered livestock-watering systems, including discussions of cost, components, and terminology, as well as some suggestions for designing and installing these systems. The strengths and weaknesses of solar pumping are compared to the main options for pumping in remote locations: mechanical windmills, wind turbines, and portable generators powered by gas, propane, or diesel fuel. Design considerations for freeze protection in water-pumping systems are also discussed. Descriptions of four successful projects and a brief resource list are included.
