It is important to understand the requirements when expanding a solar small generation unit (SGU) into a power station. These requirements ensure you're eligible to claim renewable energy certificates.
A solar SGU must be 100 kW or less to qualify for small-scale technology certificates (STCs). Systems that are currently or expanding over 100 kW capacity must be registered as a power station to create large-scale generation certificates (LGCs).
There are risks when expanding a solar SGU before your STCs have successfully passed their compliance requirements and checks. You may not be eligible to re-create STCs if the initial claim is failed and the system no longer meets the definition of an SGU. You could be asked to surrender certificates if you claim STCs that you are not eligible for. Other compliance action may also be taken.
