Switch to a solar hot water system and you could reduce your energy bill

21% of the energy used in your household goes towards hot water, according to the Australian Government (Your Home)

A simple way you could start saving on your electricity bills is to switch to a solar hot water system. Switching to a solar hot water system will, on average meet 50-90% of household requirements (Energy Rating, 2020). A solar hot water system is separate to a solar panel system and they can work independently.

What size system should I choose?

The size of your system will be determined by how many people are in your household, the amount of water used, and when you use your water.
Typically, one person will use 80 litres per day (Energy Rating, 2020). Other factors (i.e. spas and shower times) will also impact this usage.

Do I choose flat plates or evacuated tubes?

The solar collector part of the hot water system is made up of flat plates or evacuated tubes. Each option has its pros and cons depending on your climate, roof orientation and system size one option will be better than the other. When choosing your solar collector, your installer will go through the options suited to your individual needs.

What is a booster?

A booster works as a back-up heater, heating your water when there is not enough energy available from the sun. There are two main options: electric or gas.

Where should the collectors be placed?

Ideally, in Australia, solar collectors like solar panels should be placed on a north-facing roof. If you do not have a north facing roof, you can place panels facing east or west, however, the energy provided by the sun may be lower (Energy Rating).

Your chosen installer will be able to provide further information subject to your roof availability.
