Australian Solar Hot Water Rebates

solar hot water rebates

According to YourHome, hot water systems are one of the biggest energy users in the home, using 21% of all energy consumption on average. This can greatly impact household energy bills, but installing an effective hot water system, like a heat pump or solar hot water system, can help keep costs down.

In addition to long-term water heating cost benefits, solar hot water can significantly reduce your initial investment thanks to generous government rebates. Visit our Solar hot water – How it works page to learn more about solar hot water.

Avoid confusion and maximise your rebates

The situation with solar hot water rebates in Australia has been confusing, with chopping and changing state and federal government incentives. There are currently valuable rebates available Australia-wide, as well as in many states. There are three primary sources of solar rebates or incentives available to Australians.

Federal Government financial incentives

Small-scale Technology Certificates (STCs)

The Australian federal government has administired the Small-Scale Renewable Energy Scheme (SRES) since 2001, whereby households and small businesses benefit from point-of-sale subsidies for small-scale renewable energy systems, such as solar hot water. This is achieved through creating Small-scale Technology Certificates (STCs). Each STC has a monetary value which can be either credited to your installer in exchange for a point-of-sale solar rebate. 

The SRES has seen millions of Australians save thousands on the cost of their small-scale solar PV systems, heat pumps, wind, hydro, and solar hot water systems.

Victorian Energy Upgrade (VEU) Scheme

All Victorian households and businesses that have an inefficient electric or gas hot water system are eligible to participate in this scheme.  To receive a discount or rebate on an upgrade to your hot water system, you must engage with an accredited provider. The accredited providers can use their tradesperson (if they have any available) to install the hot water system and work with a tradesperson of your choice to install the hot water system.

To be eligible to upgrade your hot water system and get a discount/rebate, you must:

  • be a Victorian household or business
  • have an inefficient electric or gas hot water system.

Discounts or rebates are based on a certificate price and the average efficiency of products improved under the program.  Its factors include

  • certificate price
  • type of LED
  • the number of products replaced
  • location,
  • installation costs and administrative costs by accredited providers.

Retailer Energy Productivity Scheme (REPS)

The Retailer Energy Efficiency Scheme (REES), which ran from 1 January 2009 to 31 December 2020, has been replaced by the Retailer Energy Productivity Scheme (REPS).

The South Australian government’s REPS energy productivity scheme commenced on 1 January 2021 and creates incentives for households and businesses to save more energy. 

You can contact any REPS obliged retailers or third-party contractors, not just the retailer currently supplying your energy services, to find out what energy savings activities may be available for your home or business. There are 31 eligible productivity activities under the REPS that retailers may choose to provide. Typical activities include installing energy-efficient lighting, or installing water-efficient shower heads, and helping save water heating costs.
