We already have those future neighbourhoods, but they are powered by 4,000 acre solar installations, operated by entities we call 'utilities'. Economies of scale greatly benefit them, for the same reason that economies of scale benefit industrial-scale smelters over the https://en.wikipedia.org/wiki/Backyard_furnace https://en.wikipedia.org/wiki/Backyard_furnace garbage that was pushed by 'great visionaries' of the last century. There's no universe where someone driving for an hour, then climbing onto your roof to install a solar panel is cheaper than doing it at scale. There is no universe where an HOA wasting 40 acres of expensive urban or suburban land is more economic than a utility deploying 40 acres of solar panels, 15 miles out of town.
