About Battery Storage
When Does It Make Sense To Install A Battery
Who doesn’t want a nil bill? Households want to be more self-sufficient and less reliant on the grid by storing clean energy generated by their solar panels.
At the moment, the greatest shortcoming of solar power is that you need to use your solar energy at the time that it’s produced to get the greatest benefit. Not everybody can take full advantage of their solar panels’ output. For example, a typical working family which has higher usage early in the morning and in the late afternoon/evening, as the graph demonstrates.
This is where battery storage comes in.
There are 3 main reasons you’ll want to add batteries to a grid-connected solar power system:
- you want to store the excess energy that your solar power system generates during the day and then use this at night when your panels aren’t working.
- you want to have backup power available if the grid goes down (mostly applicable in regional areas).
- you’re tired of electricity tariff increases and want to cut the cord to the grid and never pay an electricity bill again.
If you’re unsure of the critical questions to ask when it comes to choosing and installing a battery, here’s our Battery Storage Buying Guide with the Top Ten Questions You Need To Ask.
Here’s how a solar system with Tesla Powerwall works:
- your solar panels convert sunlight to DC electricity (Direct Current).
- any surplus DC electricity that your home doesn’t use charges Tesla Powerwall.
- the inverter converts the DC electricity to AC (Alternating Current) for use in the home.
- a special type of inverter also converts AC to DC to charge PowerWall.
With batteries, both your daytime and evening electricity usage is free because:
- any appliances that run during the day can run at zero cost direct from your solar panels; and
- appliances that run of an evening can also run for free, drawing the solar energy that’s stored in your battery

Important Considerations and Battery Storage Quotes
Who Should I Choose To Install My System?
More important than the quality of the components you choose is the quality of the installation, as batteries – especially lithium-ion – are highly combustible. It’s imperative to have your battery system installed by a professional who’s highly experienced and accredited (who’s been installing battery storage systems for at least 3 years).
