Sorry for this simple question, but my searches have been fruitless.
My system is installed on a cabin that sees typical seasonal use. High, on-peak summer usage that requires significant grid energy. Many days unoccupied during the rest of the year, with very low energy consumption.
Just got my first NEM bill from PG&E, with a section titled "monthly NEM charges"... which made me worry that I have misunderstood the manner in which this program calculates the net balance due at true-up. Which of the below is true?
1) The full year kWh generated is subtracted from full year kWh consumed. Any positive remainder in kWh is charged to me (at x rate?) at true-up. Any negative result (over-production) is credited at a much lower rate.
2) A monthly NEM balance is generated, and charged according to on- and off-peak rates. These monthly NEM charges are then combined at true-up to determine the yearly settlement.
I was expecting that our yearly total production would easily offset the high summertime draws from the grid. So scenario #2 would hurt: If our energy imbalance is instead being calculated and charged to us on a monthly basis, the true-up cost to me will be much higher.
Thanks in advance for any help explaining this to me...
