If you only have a single - rate meter in your home, you need to request a change to a two-rate or interval smart meter. Grid-lite setup, what you want to do primarily is run off of solar during peak energy hours and utilize the grid during off-peak hours if you must. A three-person household with 4.5 kw of panels and 15 kWh of battery should do just fine most of the time. Avoiding grid usage is a money-saving measure and a reduction of your environmental impact, but if a couple of rainy days in a row happen, it isn’t the end of the world.ġ.5 kW of solar panels and 5 kWh of battery storage per person. You aren’t as concerned about staying absolutely topped up at all times. Using the grid as a backup, the home solar batteries you use can have a bit more flexibility. So a typical three-member household going entirely offgrid would want around 24 kWh of battery storage and 6 kW of panels to fill the energy supply to capacity in the winter. Off grid has the most extensive home solar battery setup, with the usage of each person needing to be considered for two entire days. Assume only 6 average peak hours in the winter months, and the possibility of an entire day without any solar generation at all.Ģ kW of solar panels and 8 kWh of battery storage per person. Consult your region’s meteorological data if you want to see probabilities of multiple days of bad weather in a row.

Off grid setup in an area that gets at least 8 peak sun hours on average, you want to budget your home solar batteries so that they get you through the lean times. The actual size depends on the equipment type of each user, the sunshine condition in the region, and the equipment quality of the solar energy system. The above parameters are inferred according to the electricity consumption habits of most Australian residents and are for reference only. Plug all of your appliances into this solar calculator. For more exact figures that apply to you, That’s about 8 kWh per person in the household. Between 14 and 19 kiloWatt hours (kWh) is what the average small family uses every day, depending on the region. Let’s talk about the average electricity usage for AU homes. In all of these scenarios: Remember that areas further north will get more peak production hours! This means you can reduce the number of panels slightly, or increase your storage capability slightly if you really want to use every ray of sunshine. The answer to this depends on whether you want to consider going off the grid entirely, using the grid as an emergency backup, or just using solar power to lessen your grid dependence. What Size Should My Home Solar Battery Be?

What Size Should My Home Solar Battery Be?.With these considerations in mind, let’s look at the best way to select a solar battery for home use in Australia. The cooling and pumping requirements of solar batteries for home use in these ultra-dry regions can change the target capacity dramatically. Secondly, 18% of the mainland is a desert, and a total ofģ5% of the continent receives so little natural rain that it may as well be classified as a desert. For an in depth explanation, check out our breakdown of peak sun hours by state.

It’s the sixth largest country in the world, which means home solar batteries will need to be sized based on the latitude of your home, since peak sun hours can vary significantly between the northern and southern shores. Solar batteries for homes in Australia differ in a couple of ways compared to other parts of the world.Īustralia is massive. 2023 Solar Batteries Guide For Home Use In Australia
