A solar system is designed to help offset your electricity bills each quarter by reducing the amount of energy drawn from the electricity grid by each home. There will be times when more electricity is being produced by your solar system than is being used by your household appliances. This surplus electricity will be counted by your electricity meter as an exportbefore being exported back to the main electricity grid network and earning you electricity credits from your electricity provider.
Depending on your electricity provider's import and export tariff rates and supply charges, installing a solar system will reduce your electricity bill with the possibility of gaining credits on your bill.
Depending on the size of your solar system, electricity price rises may impact how much reduction you will get in your electricity bills. A solar system that covers the dollar cost of your bill now may not do so later when electricity rates increase.
