The bill amount must be your main tariff total exclusive of any other charges such as meter reading. If you enter the figure exclusive of GST then be sure to enter the tariff as exclusive of GST also.
If you have a swimming pool or electric hot water system then it is best if these items are put onto the solar PV so you can add them into the amount. These items will use roughly 6-8kWhr per day each which roughly equates to a 1.5-2kW solar system per item.
