I have been looking into adding solar panels to my house. I would like to for the environmental benefits, but I know that my wife is concerned about what this will do to the property value of our house. Do you know if there is anywhere that shows concrete evidence as to how solar panels affect the resale value of your home? I am sure that if there is solid evidence that solar panels increase a home's value that this would be a great selling point, not only to my wife, but for anyone. Kyle G - Vancouver, WA
