Having solar panels does not eliminate your electric bill. You remain connected to the electric grid and obtain a monthly bill from your electric company. With most utilities, you have to pay a fixed monthly amount regardless of how you use the electricity. You will also be charged for any extra power being taken from the grid when your system is not producing enough power.
If your solar system was recently installed, you might need to wait a few months to see the impact on your utility bills because these are billed retroactively.
