Small-scale Technology Certificates are created to provide a financial incentive to install solar water heaters, heat pumps or solar panels in your residence or business. The certificates are part of a federal government program called the Small-scale Renewable Energy Scheme, the details of which vary from state-to-state.

A device that helps you estimate solar system size and cost, based on your energy usage needs and lifestyle, ensuring that you have the appropriate system for your home.

This is the angle or tilt that the panels are facing towards the sky. On a flat roof, the tilt is 0°. If facing a wall, the tilt is 90°. Flat or 90° is not ideal, the recommended angle is 20-35°.

A form of electrical current, in which the direction of the flow of electrons changes back and forth at regular intervals. The electricity grid and most everyday household appliances use Alternating Current (AC).

The Australian Renewable Energy Agency is a commercially oriented agency, which was established with an objective to make renewable energy solutions more affordable and increase the amount of renewable energy used in Australia.

A rechargeable battery, connecting a solar cell with battery power storage. It rations excess power so that it can be used to offset peak or night time use. Battery storage capacity is measured in KWh.

The capacity of a solar power system is commonly its output in optimal circumstances. Capacity is measured in Watts (W) or kilowatts (kW). 1kW = 1000W.  Capacity can be referred to as the size of a system, e.g. 3 kW.

One or more conductors which electricity flows through.

A kind of electrical current flowing consistently in the same direction. The current that flows in a flashlight or similar appliances, which runs on batteries, is Direct Current.

The ratio of output energy to input energy. Expressed as a percentage.
