With an older home replacing the windows and making sure your home is airtight, sealed and well insulated is going to be more beneficial than trying to go with solar energy. Your heat/cooling system is still going to leak/waste energy if you don’t fix the core issues of the home.

You'll never get a payback on replacing windows. You absolutely will with solar. I do agree with your other points though and they should be done first.

Order of importance: air sealing, insulation, window replacement. Least expensive to most expensive: air sealing, insulation, window replacement.
