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.
