Best of luck,
If it saves you money and you recieve a credit from APS then it may be a value. That would be an asset to share with buyers and give them option to keep. When power prices shoot through the roof buyers would be all over it.
It is all about what type of panels you have too. I know a solar company that leases and the clients still have a credit after lease payment.
Best of luck! Solar is the direction our community needs to move. If you would like other resources feel free to contact me direct.
I completely understand if you make the personal choice to install solar, but at his time they are not very common in the resale market. It will likely be years before much value will be actually derived from the system. Many buyers may think its nice and feel good but I doubt many are looking specifically for it at this time.
My advice, find a home you really think you want to live in for years and then install the system of choice for your benefit.
Glad to answer your question.
