On grid-scale this very much has an influence. Obviously not on individual scale. Is the influence big enough to warrant needing permits? Not sure, but I certainly see the problem.
In many areas solar panels get turned of by grid operators remotely for many hours on sunny days. In an area in the south I worked in around 50-70% of the produced power of larger installations (>30kwp) is essentially thrown away because the grid simply doesn't have enough capacity.
If many houses install off-grid solar, it's still not going to have a negative effect on the grid because the change is spread out over time.
It does mean that less generating capacity is needed over the long term, but decision makers can just get that data directly from the grid. I don't see what extra information the permit is adding.
