Home improvements typically add value to your home. Some improvements, such as minor kitchen remodeling, can add as much value as 80% of the cost to your home. Thus if you were to spend $20,000 on minor kitchen remodeling, you would likely add about $16,000 to the value of your home.
Solar electric systems go above and beyond the typical home improvement when you consider the value they add to your home. A study in the Appraisal Journal has shown that for every dollar a solar system saves per year, up to $20 in value is added to the home. This means that a solar system that saves a home $1,000 per year would add up to $20,000 in value to the home. However, in Arizona this value will not increase your property taxes.
