Significant challenges
Possible, but water will be hard. Only about 16 inches of rain falls a year, so you will rely on a well or hauled water. The sun is strong, about 6.1 hours of full sun a day, so a smaller solar array covers a household. The growing season is only about 114 frost-free days, so plan on cold-hardy crops and a greenhouse.
