Last year California was generating so much green power that they had to pay Arizona to buy the excess, because they had no way to regulate the production state wide. It was very expensive to sell. Arizona had some the cheapest power in the country as a result.But most of the "buying" is in the form of credits.
My system the other day around 3:00 was producing 5 times the amount of power I was using, and that excess went back to the grid.
Conversely, at night, the panels generated 0 and I was using power from the grid.
My net for the day was I sent more power to the grid than I used, building on my "credit" for when I need some.
On a cloudy day I will be using that credit.
It seems like a fair exchange to me.
Don’t get me started on when the told their residents to not charge their electric cars due to shortages. I can’t wait for this to spread nation wide. Significant laughter will ensue.
