There is no real course of action here as the power will just be cut. The problem is as the prices escalate more and more will turn to solar and those left on the grid will have to cover the lost revenue. The answer is to have a big installation that never requires you to return to the grid ever again. We are cutting ourselves off as they still want to charge R600 monthly even if you do not use their power. Forget the possibility of selling back to them which is just not worth the hassle as they will find a way to penalize you when you are actually helping.
