Citization needed. Actually we do not know and we are figuring this out.
Few examples:

Batteries would need to be safer, less toxic and less prone to be mined by children in Africa, also orders of magnitude more energy dense.

Which would be: there is not really a need for stationary batteries to be expensive.
It's a very common tactic by renewables maximalists, and I'm very familiar with it
"And what's the cost of building on a mountainside, and how much is maintenance?"
Why should I feel it as my duty to answer that specific question to you? Seriously curious.
So the conversation, in context, is literally this:
---
Someone: we should build panels on mountainsides
Me: how much more expensive will building and maintaining them will be?
You: Maintaining solar panels will be always way, way, waaay cheaper than maintaining nuclear. Also batteries will need to become cheaper
Me: Erm... That doesn't answer my question, and on top of that you're admitting batteries are not cheap either
---
But, again, this is on par with what I expect in such discussions
Batteries would need to be cheaper, that is all that is needed for italy. In the south, they have sun all year around.
