What is the expected life of the batteries compared with the payback period
?

Iowa is a buyback state. Batteries are optional, unless you want total
disconnect from the world. From a house sale perspective, it's better to
avoid disconnecting from the utilities. Even so, having some form of storage
(TESLA WALL?) is good, but the payback is horrid on storage. Generally
speaking, the payback period doubles. Also, when you combine time-of-day
billing with solar production, it can really make things work in your favor,
but the rules on that vary by state.

That said, I am investigating a couple of new/old tech solutions for energy
storage and recovery. One is through the use of compressed air.
Excess electricity is used to compress air in a large tank and then is
converted back to electricity on demand. The upfront cost similar, but the
10-year cost factor is a fraction of batteries. There is maintenance costs
on the air pumps, but otherwise, the system is essentially passive.

But I will probably have a minimal battery system to take a few peaks and
dips out.
