For homes in Newcastle, the main solar incentive is usually the federal Small-scale Renewable Energy Scheme, where eligible systems may receive Small-scale Technology Certificates (STCs) that an accredited installer can apply as an upfront discount. The value depends on factors such as system size, location, installation date and the applicable deeming period, so it is not a guaranteed fixed amount. NSW government battery or energy programs may also open and close or have specific eligibility rules. Check current details through energy.gov.au and NSW Government energy programs, then confirm the estimate with an accredited solar installer.
