Hi Folks,rookie question : how do I find out how much Solar power I am using from my system? background: AGL switched my meter to a Digital meter in Feb, the new bill I just recieved shows how much of my solar went to them, but not how much of my solar I used. was told after Digital meter install, my home will use my solar and surplus will go to grid, not seeing if I am using any. is there a way to find out ? otherwise these digital meters bit useless in my view. kind regards
