About the cost price of battery use in off-grid areas:

Let’s bypass hypotheticals for a moment, and look at off-grid living today: I have friends who live off-grid in Tehachapi, California, ground-zero for wind energy, with plenty of sunshine as well.
It’s well-understood by these off-gridders that their largest electricity expense, by far, is buying, then maintaining, batteries. They usually have a special room or storage shed for the batteries. The initial purchase price is huge, then they slowly go bad, losing capacity with their limited number of charging cycles. In ten years they need all new batteries.

Perhaps the use of renewable energy with the grid may be preferable to reduce the bill without having to bear the cost and maintenance of batteries. Below is an information from a renowned scientist, from one of his comments, among thousands of comments on https://www.researchgate.net/post/Does_nuclear_power_have_a_future_or_will_new_technologies_of_renewable_energy_be_developed_in_the_energy_sector#view=62cfb886905ea62122058ea9 :

"Solar and wind work well with a combined battery back up. Excess day energy charge the batteries and the batteries discharge at night.

The PV on my home in Puerto Rico paid itself in 7 years the solar water heater has over 34 years.

My electrical bill went from 144 USD per month and now is 5 to 7 USD per month and the system is more reliable than the centralized system which is quite sensitive to hurricane issues and outages."
