Australian Federal Government Small-scale Technology Certificates (STCs) apply to eligible heat pump and solar hot water systems, acting like an upfront discount that cuts the solar hot water price / cost or heat pump hot water price / cost at the point of sale. On top of this, NT homeowners may be able to access state-based hot water rebate NT style support for certain upgrades, including a heat pump hot water rebate, solar hot water rebate or electric hot water system rebate, depending on the program in place at the time.
When you add these rebates to already lower running costs, the effective hot water system price / cost can drop sharply, sometimes by a substantial percentage.
