How Jouli works (and how we make money).
Jouli is Mission Green's energy expert — free, on your side, and upfront about exactly how we earn. Here's the honest version.
Meet Jouli
Jouli is Mission Green's energy expert — a free assistant that reads your power bill, works out your exact rebate stack, sizes a system for your roof, and tells you, in plain English, the smartest way to cut your energy bill.
We built Jouli because working out solar, batteries and rebates in Australia is genuinely confusing — the rules change every few months, and most "advice" online is just a form that sells your details to three salespeople. Jouli does the maths for you, for free, with no spam.
Jouli is built and owned by Mission Green Pty Ltd, a licensed Australian installer (SAA accredited, NETCC approved, Solar Victoria authorised). So we'll always be upfront: Jouli is our expert, on your side — not a faceless comparison site pretending to be neutral.
Why is it free?
Because it's how we meet our customers. When Jouli helps you and you decide to install with Mission Green, that install is how we make our money — so we can afford to give the advice away for free. No paywall, no "premium answers", no catch.
How we actually make money (all of it)
We'd rather tell you than have you wonder:
That's the lot. If a recommendation could earn us anything, you'll see it labelled.
What Jouli will never do
- Never sell your details to a pile of installers. Your information stays with Mission Green.
- Never push a system you don't need. If a smaller system — or no purchase at all — is the smart move, Jouli will say so.
- Never claim to "compare everything". Jouli is Mission Green's expert, not a whole-of-market comparison service. Where an outside option is better for you, we'll point you to it (including free government tools like Energy Made Easy).
- Never hide a fee. Interest-free finance carries a merchant fee built into the price — we'll tell you that too.
- Never make up a rebate. Every dollar figure is dated and shows its source.
We'll even tell you not to buy
The fastest way to lose your trust would be to turn every chat into a sale. So Jouli is built to give you the honest answer, including:
"A battery doesn't pay back for you yet — here's what to do instead."
"Your energy plan is already a good one — don't switch."
"A smaller system is the smarter buy for your place."
If that means we don't make a sale today, that's fine. We'd rather you trust us for the next ten years.
Our numbers are dated, and we show our working
Rebates and tariffs change constantly. Every figure Jouli gives you is marked "as of [date]", and you can ask "How did Jouli work this out?" to see the assumptions — your usage, your tariff, the rebates applied. Estimates are estimates; your final numbers are confirmed at a proper site assessment.
Your privacy
When you save your details or book a callback, your information goes to Mission Green's own systems so our team can help you. We don't sell it. You can ask us to delete it any time at info@missiongreen.com.au. Full details are in our Privacy Policy.
- We tell you how we make money — every time it's relevant.
- We recommend what's right for you, including "don't buy", "buy less", or "not from us".
- We never sell your details to other installers.
- Every number is dated and shows its working.
- If we ever get it wrong, tell us — and we'll fix it.
