How does solar power work?
Australia has an abundant natural source of solar power, one of the cleanest energy sources and capable of meeting Australia's growing energy needs.
- Solar photovoltaic (PV) panels harness the sun’s energy to generate zero emission electricity.
- Light energy is converted directly into electricity by transforming photon energy into electrical energy.
- Having solar panels is like having a mini power station on your roof.
- PV electricity is generated at the point of demand, which means there is no need to transfer the energy long distances across expensive infrastructure.
- One megawatt hour (MWh) of solar-derived electricity avoids approximately one ton of CO2.
HOW SOLAR POWER WORKS
Enjoy a clean, safe energy system that powers your home for many years to come.
Solar power can be used in your home or business with any surplus exported to the electricity grid. It emits no fumes, pollution or carbon dioxide.
Did you know that a solar power system can help you:
• Save money on your energy bill
• Generate your own electricity
• Get paid for any excess power you export back to the grid (if eligible)
• Add value to your home or increase rental value for investment properties.
• Reduce your greenhouse gas emissions
While the technology driving solar power is complex, the process of converting sunlight to electricity is simple. Here's how it works.
THE SUN'S ENERGY
The sun's energy is available to everyone. Solar power is still generated on cloudy or overcast days, just at a reduced output. At night, when solar panels typically can’t produce enough electricity to meet your household needs, power is automatically drawn from the electricity grid in this time.
Solar power generally does not help decrease costs on your power bill from night usage. However, if you find that you have usage at night time that you would like to reduce, we have a huge range of options to help ease the pain of those constantly rising energy costs.
These roof-mounted panels contain photovoltaic cells, also known as solar cells (made from pure silicon). When sunlight (UV Light) falls on the silicon cells, they convert the sun’s energy into DC (direct current) power. Solar panels harvest and collect all of this energy and typically produce energy for at least 25 years above 80% (depending on the brand of panels you purchase).
Connected by a cable to the solar panels, the inverter converts the DC power to 240V AC (alternating current), this is the type of electricity used in your home. On some inverters, the digital display provides statistics on how much power is being generated throughout the day.
Measures in half-hour blocks both the power you use and the power sent back to the grid. The power you don’t use can be sold back to the grid if you’re eligible. This is called the feed-in tariff, a rebate which depends on your electricity retailer and state.
THE ELECTRICITY GRID
Any surplus energy your home generates is fed back into the grid for others to use. When you need additional power, the grid provides this.
