Clean electricity generation paired with the first grid-level sodium battery energy storage system can bring costs down to just $0.028 per kWh. The 10 MWh storage capacity is executed with sodium-ion cells that can be charged in just 12 minutes.
Yep. But also you need to run lead acid in a smaller charge window so you need more of them and when running out of space more panels might not be feasible - many variables in the whole thing, I don’t think there’s a universal answer, one can’t really get around setting up a small spreadsheet.
The question is then whether it’s cheaper to buy LiFePos instead of lead acid or to install more solar panels.

Agreed - it’s not that there are no space constraints at all.
