Even though I have a huge solar PV, and a 99.9% large electric house, IMPOSSIBLE in the winter . But my net for the year is nuts. My usage last month was -3100kwh.
This person is asking the wrong question. As others have stated, the goal should be for 12 months, net zero. So you put it in the PGE bank during the summer, and you take it out of the PGE bank during the winter, that is what I do. I just put in too much during the summer.Time to get a couple Tesla Powerpacks man. 2x 232 kWh storage = no more NEM.
Errrr maybe you need 5x Powerpacks.
Well the Oracle guy is specifically NOT connected to the grid, as it was going to be expensive to run underground lines to his property. So can't be the one who's energy independent but still grid-tied.funny, I posted that same article about the Oracle guy already in the other forum
From what I have read, he does not have electric heat. This makes such a HUGE differenceWell the Oracle guy is specifically NOT connected to the grid, as it was going to be expensive to run underground lines to his property. So can't be the one who's energy independent but still grid-tied.
What is your monthly winter usage for heating?Even though I have a huge solar PV, and a 99.9% large electric house, IMPOSSIBLE in the winter . But my net for the year is nuts. My usage last month was -3100kwh.
maybe 60 to 80kwh per dayWhat is your monthly winter usage for heating?
I totally agree. A properly sized system returns a Zero NEM payment at True Up. Anything more is not going to get any ROI unless someone is planning adding EV or some other big usage in the future.
I'll be totally transparent here. Someone on another forum said that they are 100% independent from PG&E (although they are still connected to the grid. I challenged them as I said it would have to be a very big, very expensive solar/battery system to achieve that. They insist they are, but refuse to give specifics, although he did mention Enphase.
Here's his post:
"I got 100% Independant from PG&E and it’s costing way less per month. Don’t have to deal with power outages either. Costs nothing to do it. Message me if you’d like help."
This is not necessarily true for some people, especially when one's summer use is many times more than that of their winter use, such as in my case. Sizing the system to meet our summer AC and pool pump with the excess summer sun means that the much less sun winter sun will not have as much affect because the two things (pool and AC) that when combined use can sometimes use over 3x's the energy as the rest of the house and are not used in the winter (pool just ran for a couple of hours on really low RPM.)I totally agree.

In general, the answer for this is going to be "almost no one, unless they specced their install specifically for off grid operation".
You've got to have batteries to make solar work. I've got 66 solar panels (7 kwh), but only 3 power walls. Wish I had 3 more, because 3 power walls only give me 20 kwh or less of power storage., not nearly enough to charge one car, much less two. Of course, I have to realize that charging one car uses more electricity than my house uses in a week but charging the car a tiny bit each night is a pain.
