Solar PV systems generate electricity from sunlight. The solar panels are made up of many photovoltaic (PV) cells which collect the light from the sun and convert this into DC current. This is fed through an inverter and converted to 240V AC to power your home. The amount of electricity you can produce depends on the number of panels and their efficiency, the size of the inverter, the orientation of your roof and the amount of sunlight in your location. Your home remains connected to the power grid so that when you generate more electricity than you need, you can feed it back into the grid.
What's right for me?
If you are looking to reduce your energy use and power charges with solar power, then there are a few things worth considering.
Your Daily Power Usage Patterns
It is important that we install the PV system that best suits your needs. By looking at your recent power bills, your National Solar Expert will understand your daily power usage patterns and size the system that maximises savings.
Your Roof Space and Orientation
Our smallest PV system needs just 10m² of roof space to generate around 30% of the average Australian household’s energy use. Larger systems will require over 30m² of roof space. Both systems have the potential to significantly reduce your reliance on the grid. In Australia, PV systems are most efficient when installed on a North facing roof.
