For this guide, agricultural engineer Brian Vick and colleagues drew on the ARS Conservation and Production Research Laboratory’s 31 years of testing stand-alone water pumps.

With current technology and costs, wind power or a hybrid wind/solar pump is usually best for power needs of 1,500 watts or more.
