I've been trying to come to terms with the concept of sharing 'my' electrons with a real utility company. In our Arizona home, not here! Here, all my PV electricity gets dumped into my own 9-ton battery bank.
At any rate, can someone clue me into the reality of what I understand to be the case, as follows:
In most states, 'real' utility companies will - because laws so mandate - pay you on an avoided-cost basis for you solar (or hydro or wind or hamster cage) electricity. But they understandably place restrictions on how much you can sell to them. My question, then, is how do utilities create this limit? Is it on historical usage (last 12 mos., for example)? Is it on the size of your service - 100A / 200A / 400A / 800A ?
Is there one great big fudge factor going on here?
I would be very interested in your real-life examples. I do plan to emplace as many PV panels as my service permits in our Arizona house. Here, I'm limited by the size of my charge controllers, a limit that does not apply to those of you on-grid....which I'm guessing is, not counting me, d*mn close to 100% of this forum....
