Our daily average over the year to cover the line rentals we need to make around 13kw a day. That's just so we don't get a bill so of we make anything over 13kw we should make credits towards our next bill. If you can get a 5kw system for $6500 interest free why wouldn't you. I might even get a 5kw system for the shed that would take us from 30 panels to over 50 lmfao.
Here we average over 1yr 15kw per day from the unit (18) panels
