I'm not sure what "more pv" means here, apologies.
I see your point, in your situation that's great, but I live in an Nth floor apartment in a London borough, I don't have an option for solar, nor for a wall socket to power an EV, nor do any of my neighbours. We're entirely at the mercy of Freeholders to consider putting EV charging in and _only_ charging us the price of a small motor vehicle for the privilege, if they'll do it at all.
I suspect a significant percentage of the population, who like myself live in large cities or suburbs are in a similar position.
Someone told me recently that a mandate is now in place for new-build to at least build infrastructure to support EV chargers in bays, even if they're not built ahead of time. Of course given the racket that is property development, they'll not put them in and charge you a pretty penny to add it after the fact.
