A solar system lowers your monthly power bill. But there is a growing body of evidence that a home solar system increases the resale value of a home more than the initial investment in the system. Follow the links below for some of that evidence. Berkeley found home solar increases the value 1 of a home by $3.00 per system watt. Zillow2 says home solar increases resale value by an average of 4.1%. The Appraisal Institute found that homes increase $20 in value for every $1.00 in annual energy savings3 that solar can provide. In addition, some lenders include in their calculation the cost of living in a home to determine a customer's ability to keep with mortgage payments. Those lenders will naturally be willing to lend more to solar homeowners since living costs in those homes are lower. This makes solar homes easier to sell and so possible to sell for more.
