Solar power in North Dakota has been a little-used resource. The state ranks last on installed solar power in the United States, with .47 MW of installed capacity.[1][2] Solar on rooftops can provide 24.6% of all electricity used in North Dakota from 3,300 MW of solar panels.[3] The most cost effective application for solar panels is for pumping water at remote wells where solar panels can be installed for $800 vs. running power lines for $15,000/mile.[4]
