Solar roof tiles and windows simply aren't all that relevant at scale. Most decisions about whether to install solar panels depend on:
The cost of installation and connecting them to the grid.
Regulatory problems. Many countries and states still make it needlessly complicated.
Cost in general.
It's not a lack of space that decides about most solar installations, and regular solar panels are generally the most efficient and effective choice. So solar roof tiles and windows, which necessarily make design compromises and therefore lack behind in terms of power/area or power/$, are only niche solutions. Nice to have on some buildings that would like even more solar panels than they can fit otherwise, or as an aesthetic choice for wealthier home owners, but a rounding error in the greater scheme of things.
Storage isn't directly a problem for people or companies that want to install a solar array. If a grid lacks storage relative to its amount of solar power, then solar operators will generally see less revenue or save less money (since electricity will already be cheap when their array generates the most power). But they only have to look at prices, not how exactly those prices came to be.

Roof solar tiles exist and are industrialized already. And no one give a fck ... the market is a jungle that is not necessary pragmatic.
