Battery Calculator


Calculate savings when adding a battery to your existing solar panel system

Simply input your electricity tariff, the battery you are considering, and upload your smart meter data to get definitive battery savings and payback based on your real-life 12 month usage.

How it works

By uploading your smart meter data we can see exactly how much spare solar you have throughout the year to charge a battery, and how much electricity you use after sundown.

We use this data to calculate exactly what your bill would have been for the previous 12 months if there was a battery charging from the solar during the day and powering your home at night.

Why do we need your postcode?

Your postcode lets us a) use sensible default electricity rates and b) determine your network's peak, off-peak and shoulder time periods.

How do I get an NEM12 File?

If you have solar, you have a smart meter. If you have a smart meter, you can usually download its data from a web portal. Click here to see how to get your smart meter data.

You'll get it as a .csv file. That's the file to upload here.

If you have a smart meter, it likely has 30-minute interval data that can help us figure out how a battery can change your electricity bills.

You can get this data from your electricity network provider (DNSP). Check our support article to see how to get it.

Once you get the data in a CS file from your DNSP, upload it here. Our tool will then show you what to expect.

Got it, thanks!
