Find the right solar and battery for your home
Answer a few quick questions about your home and power use. We'll recommend a system size and show what it costs after rebates, what it saves and when it pays for itself.
How it works
No jargon, no sales calls. Just a clear starting point before you talk to installers.
Tell us about your home
Your postcode, any solar you already have, who's home during the day and your latest power bill.
We size your system
We model your home hour by hour through the seasons and test solar and battery sizes against your use.
Compare three options
See upfront cost after rebates, yearly savings and payback side by side, with the best match for your goal.
What you'll find out
The right solar size
Enough panels for your use and your roof, without paying for power you'd sell back for a few cents.
The right battery size
Small, mid-size and large options, sized to how much power your home uses after dark.
Cost, savings and payback
Upfront cost after the federal battery rebate, your bill before and after, and how long it takes to pay off.
