You will continue to get a monthly bill from PG&E. However, once you go solar you will be on the Net Energy Metering (NEM) program. Once on NEM, you are only required to pay the minimum monthly fee for your electric bill (typically $5 to $12/month). You pay your gas bill as before. You will also have a statement that shows the running total of debits and credits resulting from your solar system generation and your usage each month. At the end of 12 months, PG&E will issue a true-up bill. If your debits exceed your credits, you will owe the balance.
