I dont think solar pannels on ones home are a good indicator of ones financial solvency. Being as She mentioned how much She is projected to save, I would think she is making a financially prudent move with the purchase (or are they leased? Out here they can only be leased). Now.....If She was to state, "I keep my house at 42* all year so I can wear my new fur coats all the time!!"......THEN, I would consider her in the more wealthy class of Americans, AKA "Rich". Or..... I would think She was insane. Regardless, in many cases the two go hand in hand.
