What? No. Economies of scale don't work that way. For example, rooftop residential solar is substantially more expensive than a big field of solar, or putting them on top of large industrial buildings. Labor costs hit residential solar much harder.

Depends on the grid. If the lines and transformers are already used close to their limit, more smaller buffer batteries and smaller solar installations, closer to the user, could be more efficient and not require grid adjustments. The closet to the user, the less grid adjustments are needed.

Industrial roof solar should be standard in any new building by now. Companies need the power in the day and it can be used without even needing to use the grid.
