Looking to reduce your electricity bills? Then Solar might just be the answer!

With electricity prices on the rise and millions of Australians now living in homes with solar photovoltaic (PV) systems on their rooftops, there has never been a better time to consider going solar. Here at Weather Wizard we offer two types of solar systems:


This is the most common form of solar system installed in Australia. The inverter converts the electricity generated by the solar system – which is direct current (DC) – into AC electricity so that the power generated is compatible with the grid. Most houses with grid-connect solar systems use solar power first before sourcing electricity from the grid. When the panels are not producing electricity at night, electricity is supplied from the electricity grid.


Grid-connect PV systems with battery back-up (sometimes referred to as uninterrupted power supply or hybrid solar PV systems) are becoming increasingly popular. With solar customers in many states now receiving a low price for electricity sold back to the grid, battery back-up systems can be a viable alternative as they use the electricity stored during the day to run your house at night. They also have the advantage of being able to supply power during power outages.

How solar saves you money

When you’re producing your own power, you’re buying less from your retailer and selling your excess to them. Consider the following examples. If you have 3kW of devices running and you’re producing 2kW, after one hour you would have consumed only 1kWh instead of 3kWh, saving between 45c to 60c in that hour. If you’re producing 3kW and only using 2kW, after one hour you would have sent 1kWh back to the grid and not purchased 2kWh, saving even more!

Choosing the right system

Firstly, you need to check your power bill, as it will state your average daily consumption in kWh. Then you need to consider when you use your power, as you want to cover your daytime consumption as a minimum. Each kW of solar power will produce on average approx. 4.6kWh per day, but this will vary based on your location, roof orientation, shading, etc. So if your average daytime consumption was 12kWh, you’d need at least a 3kW system. If it was 20kWh, then a 5kW system would be more suitable.
