Home battery storage works by storing excess electricity generated by your solar panels during the day, so it can be used later when your home needs power, especially at night or during blackouts or brownouts.
Without a battery, you only benefit from solar when the sun is shining. With a battery, you can use your solar energy 24/7 and save (or even earn) more. Solar alone won’t work during a blackout, while a battery with backup capability keeps your lights, fridge, and Wi-Fi running even when the grid is down.
There are several rebates and incentives available across Australia to help reduce the cost of home battery storage. These programs vary by state and territory, and our friendly team can advise you further on what you may be eligible for.
If you have existing rooftop solar, you will be aware that your panels generate a lot of energy in the morning and the middle of the day, just when most people are not home using appliances. Therefore, you only benefit from solar when the sun is shining. With a battery, you can use your solar energy 24/7 and save (or even earn) more.
Additionally, in the early days of solar energy, the feed-in tariffs (the money you make from feeding your excess solar-generated power back to the grid) were very attractive, encouraging the early adoption of solar energy. But Australia now has the highest solar uptake in the world, with around 30% of households having rooftop solar. As such, these days, you aren’t going to make much money, if at all, from feed-in tariffs. Therefore, it may make better economic sense to invest in battery storage so you can harness and store that valuable energy for when you need it, i.e., when the sun goes down and everyone is back home.
A solar battery storage system will:
A solar battery storage system is smart. It only sends electricity back to the grid when it’s fully charged and can’t store any more. And it’ll only draw power from the grid (which you must pay for) once its stored power is totally depleted. This means your solar battery will fully charge during the day and give you its stored electricity once your panels have stopped generating power in the evening. Overall, you’ll draw (and pay for) less power from the grid, saving you money in the long run.
For most homes, a home power storage battery will give you enough power for a whole night, but this can also depend on a few different factors, including:
The prevalence of natural disasters is increasing due to climate change, including floods, fires, and cyclones. Having the correct-sized battery storage to complement the rooftop solar means that you may be able to power selected circuits during a blackout if the grid is down, which is happening more often due to these disasters and ageing infrastructure. If you have battery power available, the battery will kick in automatically. Depending on which circuits you’ve chosen to receive backup power, you may not even realise that the grid is down.
