Solar Curtailment

What is solar curtailment?

There are times when the wholesale price will be negative due to an abundance of cheap renewable energy on the market. To limit the impact of negative Feed In tariffs for our customers, there's a number of steps we're taking. 

Solar curtailment is one of these options. It involves Amber limiting the solar energy you produce during periods when FiTs turn negative, to restrict the amount you export at these times.

Who is eligible for solar curtailment?

Amber's SmartShift Compatibility Checker should be your first stop when looking to check if an existing or intended battery or solar purchase is compatible with Amber. You can also head to this FAQ for solar compatibility information.

If you are already a customer and a compatible set up, please register your system from the device tab of our app. 

If you already have a battery optimised by us and your solar system is of a different brand to your battery, but still in the compatible list, you can add an additional system from the SmartShift settings page which you can access at the bottom of the device tab.

There are two types of curtailment, which one you get may depend on your system set up. Please see the links below for information on the different types of curtailment;

1. Load following curtailment
2. On-off curtailment
