Installing Solar - What Every Contractor Needs to Know

All Distributed Energy Resources (DER) including small-scale solar PV, battery storage and other small generators, must now be registered on the AEMO DER Register.
The DER Register has been designed to work in with existing network operator DER installation registration processes to minimise any impact on contractors.

Below are the 5 critical steps contractors need to know about DER installations:

Step 1 – Apply to the network operator for a connection and receive approval

Step 2 – Customer agrees and installation goes ahead

Step 3 (NEW STEP) – Electrical contractor to install the system and collect information about what is installed on-site. 

Step 4 (NEW STEP) - Electrical contractor to provide information to the network operator/AEMO DER Register portal.

Step 5 - Network operator approves data, and AEMO website generates a certificate which can be downloaded by the installer from AEMO’s DER Register portal.

Complying with the DER register is directly linked to the terms of the approval to connect, or the connection agreement, between the network and the customer. This is the contract that permits the customer to generate electricity while connected to the network.
If the required data is not provided to the network operator, the customer’s generation may be disallowed by the network.
