I was going to recommend a generator for backup, but a car does work great for that too. The marine or hybrid battery is quite possibly getting a little old as well. If you has a few usb chargeable flashlights, they can be handy for charging during the day for using at night. The want-to-do list is always growing, so figuring out what on the list needs to be done first becomes the time organizer for me - of course the little one is alowed to cut in line to the top of the list :) Unless you're purchasing a multi-thousand dollar turbine, i'd focus on solar until i had enough for my needs. Turbine's also need a battery setup more than solar panels do.
