Rain
Rain can supply much of a household's water with a large tank. A garden mostly waters itself in normal years.
About 45 inches a year (PRISM, 1991 to 2020 average)

The typical well here is about 140 feet deep; a well typically runs $8,000 to $17,000
Growing season
A full season for most vegetables.
About 182 frost-free days, USDA zone 6b; last frost about April 23, first about October 23
Sun
Good sun. Size the array and battery bank for winter.
