If you are installing an energy efficient hot water system, you may be eligible for a rebate  of up to $600 under the REES scheme. The rebate will be higher if you are installing a solar system, but is not limited to solar.

If you are upgrading to a solar system, in addition to the REES rebate, you may be eligible for a Small-Scale Technology Certificate rebate (see Renewable Energy Target).
