Solar Hot Water Rebates


Solar hot water systems use solar collectors (tubes or panels) to absorb energy from the sun to heat water for your home. The heated water is then stored in an insulated tank for when you need it.

With a solar hot water system, you could get between 50 and 90 per cent of your hot water for free.

If you replace an inefficient hot water service with solar, you can usually recover the upfront cost of the new system in 5 to 10 years - you will use the sun as a free source of energy and save the cost of heating water with electricity.

Benefits of Solar Hot Water

The benefits of solar hot water far outweigh the upfront cost:

  • The difference in cost will be paid back quickly, as you'll spend less on heating water.
  • A solar hot water system can increase the value of your home.
  • You will reduce the amount of greenhouse gases your home produces.

Getting the most out of a Solar Hot Water System

  • In cold and temperate climates solar hot water systems are likely to need protection from frost.
  • Positioning your system to face north or to avoid shade will help it to operate at peak performance.
  • Shade from trees and buildings can reduce the efficiency of some hot water systems.
  • If you can find ways to save water, you could save money by buying a smaller system than you would have otherwise needed.
