A roof mounted solar array easily adds $20,000 - 25,000 to reroofing a house just in labor (assuming two electricians for one week on either side of the reroofing with labor priced at $150/hr)
If I was buying a house with a solar array on the roof I would consider it to be a liability that is going to add to the TCO of the home and ask for a discount to cover the future costs of removal. The labor to remove and replace the solar array when reroofing is never going to be paid for by the solar array, it’s just an added expense to the TCO of a home.
There are plenty of people who are not aware of the added costs of a roof mounted solar array, I just happen to be aware since I sell and run electrical work for a living.
Why do you need two electricians for a week? My rooftop solar array went up in an afternoon. They had three labourers. The (singular) electrician came in separately and worked for under and hour.

Since all of the scaffolding or whatever is already up for the roof work, if anything the solar ought to be cheaper, in that scenario.
I'm not even talking about the fact that panels MAY act like a pool for resale. Some people DO want them--again depending on your locale--most, at this point, do NOT where I live.
I was looking primarily for cost reduction and a very small percentage of saving the environment or whatever you want to call it. But; depending on your locale, home structure, etc, solar may not at all be that. If you're leaning more on the side of energy independence and eco-friendliness, maybe it's a better fit for you.
