$40 a month is a deal compared to going off grid.

In a nut shell to go off grid you need to first save as much electric power as possible.
Then you need to convert most if not all your heating needs to natural gas or propane or solar thermal.
After that figure out how much power you use per day. Then install 2 to 4 times that in panels and size the battery bank for about 4x what you use in a day. Get an inverter and not the cheap ebay ones to power your largest demands.
After all that you will still need to buy a backup generator.
Typically start up costs are usually starting well over $20,000.
Then once you think the setup just might break even the inverter or charge controller will suddenly quit. And you have to replace the batteries at some point, between 5 and 10 years if you are lucky and 2 to 3 years if you are unlikely.
