Rooftop solar doesn't require additional land to be purchased, reduces the need for more transmission lines, and reduces transmission losses. I don't know how big these all are but it seems plausible they make it a better deal than industrial solar.
Batteries on the other hand feel like they take less space and thus could be colocated near consumption without having to be on consumer property. Warehouse size within the city. Transmission costs would be minimal.
It doesn't do any of these things.
I can't put PV on my neighbours house, I have to buy land to put it on. My home still needs a grid connection so all that infrastructure still needs to exist. Except now it's even more complex.
PV and energy generation in general benefits massively from economies of scale. Home generation doesn't have that.
