Melbourne households may be able to reduce the upfront cost of an eligible solar system through federal Small-scale Technology Certificates (STCs), with the value depending on factors such as system size, location, installation date and certificate prices. Victoria’s Solar Homes program may also offer rebates or loans for eligible households, subject to current funding, property and applicant requirements. The relevant government program decides eligibility, not SolarWise or your installer. Check solar.vic.gov.au and energy.gov.au, and ask an accredited installer to show any incentives separately on your quote.
