in. However I would very much doubt you would get a $1 to $1 increase for the solar panels. More likely it would be a small fraction, maybe 25% of the panel purchase price. A mistake many people make is assuming they can get upgrade value back out of the house when they sell it. Many upgrades are this way and solar panels would not appeal to everyone since you have to pay for the value up front (including if you purchase a home with one) pricing the home higher than others of similar situation and they are so rare that there will be no comparable houses with them.
