1. How do solar systems work?

A solar system uses the suns energy as the primary means of heating water via direct sunlight or in the case of a Heat Pump extracting the warmth from the air.

2. Which type of solar system should I install?

There is little performance difference between roof mounted (save space on the ground), split system with tank on the ground (improved aesthetics), or Heat Pump (if lack of direct sunlight).

3. What is the backup booster?

On average solar energy produces 70% of your household's hot water, therefore 30% of your hot water must be boosted when sunlight is unavailable or insufficient, such as during the winter months. Gas and electric booster systems are available to suit your homes power connection.

4. What are the purchase/installation costs?

Solar hot water systems are more expensive to purchase and install due to the additional components required. However with increasing electricity and LPG running costs, combined with current State and Federal Government incentives, the initial extra cost is more than paid back over the life of the system with the $ savings gained from a reduction in power bills.

5. What are the running costs?

Using the suns energy solar hot water systems have the lowest running costs of any water heater. The amount of saving will depend if you use a gas or electric booster, and the size of the storage tank. This means the amount of solar heated water used versus booster heated water used - the greater the booster heated water used the greater the energy consumption.

6. What size should I select?

It is important to understand that the greater the tank storage capacity the greater amount of solar heated water can be stored. Therefore the smaller the tank storage capacity the greater the reliance on either a gas or electric booster to top up your hot water needs - this will also top up your energy bills! You need to consider the available space for installation and your available budget for both initial purchase and ongoing running costs.

7. What is the impact on the environment?

Solar hot water heaters and heat pumps are powered by renewable energy therefore reducing electricity consumption and reducing greenhouse gas emissions that result from its production.

8. What are RECs?

RECs are Renewable Energy Certificates awarded by the Federal Government to appliances that use renewable energy to produce hot water. The number of RECs your installation is eligible for depends on the system's capacity, efficiency and installation location within Australia. One REC is created for each megawatt hour per year (MWh/yr) of electricity displaced by an eligible installation - the higher the RECs the greater the efficiency.

9. What are Rebates?

In addition to RECs the Federal and NSW State Governments are currently offering rebates for converting to solar water heaters and heat pumps.
