Can you see daily usage and production on the electric company's web site? Typically I've only been negative Dec-Feb.
I have 2 Tesla Powerwalls and the app shows real time production and where it is going. I'll have to to watch it and see how much power the heat pumps are sucking. I suspect we will go negative given how much power DW's Leaf uses driving 70 miles 7 days a week. I could put in another set of panels but DW can retire in just over 3 years and then we would be SO over generating I don't know that the extra panels now would be worth it.
