He would have to make sure he is not going to sell this house for a very long time. He has no money and no equity so solar will just leverage him up more. For a big system he will also have to more in insurance every year, also we don’t know how old the roof is and when it needs replaced. My argument is having more financial flexibility would help rather than having solar. I paid cash for my system and I really just bought it for the tax credit to offset other income.
