You will find the different meters and usage data on the second page of your bill. Please be aware that we only have visibility over the solar you feed back into the grid, so if you are looking for the total amount of solar you generate, you need to refer to your inverter.
On your bill you have one or two or three (maybe more) items on your bill.
the item that states "Feed-in Tariff" is the income from your solar panels.
