Hi @Michelle.
Thanks for your post and welcome to the Community.
The easiest way to explain how your solar system works is:
- The solar panels produce DC (direct current) electricity
- The electricity is fed into your solar inverter, that converts the electricity into AC (Alternating Current) electricity
- The AC electricity is then used to power appliances in your home
- Any excess generated electricity is then fed into the electricity grid
- You would then receive any feed in tariff credits (FIT) on the excess electricity
- At all other times your electricity consumption is drawn from the grid
The best way to save money with your solar system is dependent on your families situation. To lessen your dependency on the electricity grid - you might find it best to use majority of your electricity consumption during the day. However if your family uses most of their electricity at night then you would best to turn off all unnecessary appliances during the day to boost excess electricity being fed into the grid.

If you want to send a private message to me with your AGL account details, I can investigate your account further and see if I am able to breakdown your current consumption versus generation. You can send a private message by this link.
Thanks!
