On page 1 of your bill, there are a few dollar amounts shown. The Current Electric Monthly Charges, shows the Electric Monthly Charges, which solar does not offset. The bottom amount allows you to track your YTD Estimated NEM Charges at True-Up.

The table found on the 3rd page of your NEM bill shows your energy usage by months and if you have charges or credits. If you produce more energy with your solar than you consume, you will see a - negative (credit) in the Net Usage column. This will be reflected as a credit in the Estimated Total NEM Charges.

If  you consume more than your system was designed to produce, you will see a positive (charge) in the Net Usage column.

To stay connected to the grid, the utility company charges a Minimum Delivery Charge each month. This charge is what you pay monthly and it will affect your annual True-Up bill.

This portion summarizes the NEM energy charges. At the bottom, you can see a snapshot of your total NEM charges year to date. If this is a positive number, you might owe this at your annual True-Up.
