Storage may not even be needed. Or be very small compared to what's used elsewhere. Eg. the boats mentioned in article: if their 'solar roof' is big enough, and they're only used during daylight hours, they might be run without any batteries. Simply PV panels -> converter -> motor. Likewise, some activities that use more power could be limited to those hours where solar power is plenty. On a large AC grid it's difficult to control the consumption side. But on a small/local grid (or single-building setups), much easier: short lines between producers & consumers - literally.
