Advantages of home battery storage: all you need to know

Climate change is on top of everyone’s mind these days. News on sustainability is hitting the headlines every day, and which countries are (or not!) ready to take serious action on environment is a big concern. Coal and other fossil fuels are being seen as the villains of the climate change story and renewables are the heroes.

Front and centre of the renewables debate is home battery storage. Battery storage technology supports the renewables revolution by letting you store solar energy for most of your home’s power needs even after the sun goes down.

But isn’t that what solar PV systems have been doing all along? Nope! Traditional solar systems generate clean energy which can be used as long as the sun is shining. If you generate ‘excess energy’ in the day, you can pump it back into the grid and earn a fee for it, but then you’ll need to again buy energy from the grid to meet your nighttime electricity needs. Battery storage can get rid of this back and forth of energy by storing the excess solar energy produced during the day so you can use it at your home later at night.

Here are the major advantages of a home battery storage system:

Reduced dependency on the grid = Lower energy bills

Since battery storage lets you use all the energy generated by your rooftop solar panels yourself, it helps lower your dependency on electricity from the local grid at nighttime. This increased self-consumption of solar PV in turn leads to lower energy bills, or possibly in the future, no energy bills.

More renewable energy = Better for the environment

Battery storage is good for the environment because it uses natural sunlight instead of fossil fuels for generating electricity. The upfront cost for solar systems is lowering over time and more Australians are being encouraged to adopt sustainable energy solutions. In fact, according to the Climate Council, by 2018, going off-grid by installing battery storage could be cost-competitive with staying connected as the price of battery storage falls and grid electricity remains expensive.

Stored energy = Blackout support

Another benefit of storing energy is that in case of a blackout, a home battery system should be able to keep some of your home’s appliances running for a number of hours even when the power is out.

The home battery storage technology is very new and developing all the time. For more detailed information on who’s providing home battery storage solutions and how it costs, check out our battery storage guide.
