I'm not sure that grid-tied solar systems actually provide any massive
reprieve on utility generation, because the hours that installations can
produce energy is when demand is at its lowest (fair point, working from
home this past year has probably skewed that, but...).
Demand tends to ramp up in the evenings, which is when solar cannot work
anymore. And considering that there are more grid-tied solar solutions
out there with no storage, the grid has to handle that ramp up for the
evening loads, likely more quickly than they would have if there was no
distributed solar generation.
I'm also not sure about the state restrictions on the % of customers
that can connect their solar systems to the grid, but I'd imagine it's
somewhere between 10% - 20%, last time I did a spot-check on various
U.S. states.
