Solar power – renewable energy

Renewable energy can be defined as the energy that comes from an inexhaustible source such as the sun, wind, hydro etc. (unlike fossil fuels such as coal, gas and oil).

The energy of the sun, or solar energy, is a form of renewable energy that can be used in two different ways:

To heat water directly in a solar hot water heater, or
To generate electricity using Photovoltaic (PV) technology.

PV or solar cells are composed mainly of silicon. Energy, in the form of solar radiation striking those silicon atoms (under certain conditions), can release free electrons, which can move and form an electric current.

PV panels have been traditionally used in remote areas where there is no access to grid electricity. However, a growing number of customers, despite having access to grid electricity, are making use of this technology. This is largely based on environmental reasons and a desire to generate a proportion of their own energy use.

Most of Aurora's electricity is supplied from renewable hydro electricity and Aurora Energy is keen to encourage the use of new renewable technologies. Net metering enables customers to use Aurora's grid like a large battery, exporting energy during the day and importing electricity over night. Customers are billed only for net energy import plus standing charges.

Whilst the initial capital costs are still high (relative to grid connection in areas served by Aurora's distribution network), there are little or no running costs for PV systems. Combining a PV system with stringent energy efficiency measures could reduce your electricity bill considerably (you can save money through energy efficiency without necessarily installing a PV system).

Net Metering Buyback Scheme

To facilitate grid connection, Aurora introduced its Net Metering Buyback Scheme in July 2000. Since then, more than 100 residential customers have installed grid interactive PV systems ranging between 0.45 kW to 3 kW average capacities.

The Australian Government's PV Rebate Program, was introduced to encourage the long-term use of photovoltaic technology. The rebate is based on the peak PV output of the new PV component of the system.

The minimum system size is 450-Watt peak output. There is no maximum size, although the present rebate of $8.00/W for new systems is capped at $8 000 for each installation. Extensions to existing PV systems can receive rebates of $5.00/W capped at $5 000.

You can obtain the latest information about the rebate conditions, and copies of an application form for Photovoltaic Rebate Program from the Australian Greenhouse Office (external link) or by calling 1300 138 122.

You can also consult a Renewable Energy Systems supplier (external link) in your area regarding costs and estimated annual electricity generation of PV systems.
