Start with the battery and inverter first. If there is a power outages, you will have power for the fridge and TV. I am fond of Nissan Leaf modules.

Then, plan out the purchase of a dual-fuel generator as a back up.

The last phase is adding the solar panels and charge controller...if you wait on the panels, you can get the newest type, with the best cloudy-day performance.

You can get a sunburn on a cloudy day, so some frequencies of energy are making it through...

Just a few thoughts and suggestions. Best of luck.
