Is the grid prepared for this working at scale? And it seems to me that
all solar would "sell" at the same time, driving down the price to zero
or even creating an excess, while all the ones in this system would need
energy at the same time (night) driving the price up, therefore again,
needing some kind of storage.

I did some research and calculation of how much it would cost with
hydrogen storage for a solar powered house in sweden, and 10 years ago, I
found a pilot project in northern sweden, and the cost was about 1 million
EUR (give or take).
 
A couple of months ago I had a look around, and the cost as far as I could
estimate, for storage, had dropped to about 500k EUR.
 
If the decrease in cost continues, it would become feasible with solar in
sweden in about 12-20 years time if you're doing it as a hobby.

And therein lies the problem.  Most of the "storage" systems are on an
exponential increase growth curve.  But total energy usage per
country/worldwide is so large, that it will take twenty plus years of
"doublings" each year before the storage tech is on par with today's
level of consumption.  Meanwhile, in twenty plus years, usage has
itself likely increased, so storage is still behind in total, just not
as far behind as it is today.

Yet, if the 'climate folk' are to be believed, we need to achieve zero
carbon input into the atmosphere yesterday, not twenty plus years into
the future.

So assuming the "no carbon" goal is required, we can't get /there/ from
/here/ without something like nuclear to handle what 'storage' claims
it will be able to do, in twenty plus years.
