Excess charge means more positive charges than negative charges, or vice versa.

I thin that "there can be no net charge" is not a correct usage. It is an abuse of language that I have often hear, with the meaning that "there can be no net charge other than zero." The correct way to say it is that the net charge is zero, which is the same as "no excess charge."
