Yes, to sell your excess solar energy, you must register your XOLTA battery system with a production electricity supplier as soon as possible. A production electricity supplier is an electricity company that purchases power from solar panels and wind turbines. It is also a legal requirement.
When should I register?
As soon as you have received your GSRN number from your electricity grid company, either by mail or email. If you have not yet received a GSRN number, you can call your grid company and request it.
