Yes, so long as you are staying at the same location, not making any prohibited modifications to the solar system and your Sorted account is set up in the same name as your previous account.
Solar credits are applied to your electricity account and offset your usage from the grid. If you generate more than you use in a particular billing period then that credit will be transferred to your Sorted Wallet. You can use this credit on future expenses.
The solar rebate is applied to your account when the billing period is complete and we have received confirmation from the distributor about how much you have fed in to the grid. If you have a smart meter this will be monthly. If you have a basic meter then this will usually be quarterly.
We have a very competitive feed-in tariff that is higher than the government recommended amount. You can also keep track of what you are feeding back into the grid (and how much you are saving!) with the Sorted App.
