I don't have that much unshaded roof either, but it is still worth having the PV.
I have a useful PV array at my home but I need a good bit more to power automobiles. However, I don't care if the utilities start using major PV and putting it on the grid. To me the grid is a good thing. I am not flush enough to build the power generation and storage to cover all my needs. Part of me wants to be childishly pissed at Duke Progress and tell them to stick it somewhere dark, but my inner parent knows I need what they offer. A far more useful scenario is for me to not commute so dang far. Then I can run a light EV even with my smallish system. Back to the point that many homes are unsuitable for PV (a truism). Each home need not support PV for this to work. I think it is reasonable to consider solar micro grids for communities - where the individual homes are shaded or too small. There is a whole lot of sunlight out there, that is why it makes some much sense to start using more of it. There is an enormous amount of abandoned or unused acreage in Raleigh near where I live. As for storage, there are other options than batteries. I hate to mention here, the dreaded hydrogen storage cell - but it is just a tank. There is a good case that can be made for using hydrogen as an analog to pump storage for renewably sourced energy - energy that is inconsistent in production (wind and sun). As inefficient as electrolysis and fuel cells may be for transportation use, the numbers look much better for large scale storage compared to batteries. I think the grid is our friend and this is one way it pays off.
