Significant challenges
Possible, but water will be hard. Only about 17 inches of rain falls a year, so you will rely on a well (near 220 feet here) or hauled water. The sun is strong, about 6.2 hours of full sun a day, so a smaller solar array covers a household. The nearest roads are often dirt tracks, so plan to build or maintain your own access.
