Canberra households may be able to reduce the upfront cost of an eligible solar system through the federal Small-scale Renewable Energy Scheme, usually applied as an upfront discount by an accredited installer. The ACT Government may also offer energy-efficiency or battery incentives, loans or rebates from time to time, but availability, funding and eligibility can change. Check current details through the ACT Government and energy.gov.au websites, and ask an accredited installer to explain the certificates, system requirements and total installed price before signing. Any final approval depends on the relevant government program and your circumstances.
