For hot water nsw homeowners, rebates and incentives make the decision even easier. Federal Small‑scale Technology Certificates (STCs) effectively act as an upfront discount on eligible solar hot water systems and heat pump units, reducing the solar hot water price / cost and heat pump hot water price / cost at the point of sale.
