The customers we said no to.
A seller who never says no isn't being honest — they're just taking orders. Here are the real times we told someone to wait, buy smaller, not buy, or go elsewhere. We'd rather lose a sale than sell you a system that won't pay off.

Why a good installer
sometimes says no.
An installer paid only when you buy is structurally biased towards a "yes". The only way to be genuinely honest is to be willing to give up the sale — so that's exactly what we do when the numbers don't stack up for you.
Most sites selling solar and batteries have one answer to "should I buy?" — yes. That's not advice, it's an order form. We think the opposite: the moment a seller is willing to talk you out of a purchase, everything else they tell you becomes worth more. We'd rather lose a sale than sell you a system that will quietly fail to pay off, because the cost of a bad-fit install — to you, and to our reputation — dwarfs what any single sale is worth.
In practice, the honest "no" comes in four shapes:
- Wait. The timing is wrong — a rebate or price change, a roof that needs work first, no solar yet, or a feed-in tariff that still pays you well. Buying now would lock in a worse outcome than buying later.
- Buy smaller. The system you asked for is bigger than your genuine usage. A right-sized system pays back better, because the extra capacity in an oversized one sits half-used and still has to be paid for.
- Don't buy. On your real usage, the system simply won't pay back within its warranty and throughput life. A "saving" that arrives after the warranty lapses isn't a saving.
- Go elsewhere. Another solution — or another supplier — genuinely fits you better. If that's the honest answer, we'll say so and point you the right way.
None of these is charity. It's simply how a business you can trust is supposed to behave. If you want to see the mechanism that keeps us honest — not just the promise — read on.
The proof is mechanical,
not a promise.
Anyone can put "honest" on a website. The difference here is that our honesty is measured and published live — you don't have to take our word for it.
Our free AI energy advisor, Jouli, gives real advice — including "not yet", "buy smaller" and "don't buy". To stop that from being just a tone of voice, every reply Jouli gives is audited by a second AI critic — we call it the Red Pencil — that checks the answer for the customer's benefit and logs it whenever the advice is to walk away from a purchase, or whenever it steers a customer towards a Mission Green product.
Those logs are published live on our public honesty record. It shows the walk-away rate (how often the advice is "don't buy / wait"), the steer-to-Mission-Green rate, and the pass rate — read straight from the data, not written by our marketing team. That's the point of this whole page: trust should be something you can measure, not something we simply claim.
The times we said
no — in practice.
Below are illustrative examples of the kinds of "no" we give. They are clearly-labelled placeholders, not real customers — we won't invent a name, suburb or dollar figure and pass it off as a real person. Verified, anonymised real cases will replace them here as they happen.
Wait: a low-usage home better off without a battery (example)
This is an illustrative example of the kind of advice we give — not a real customer. It stands in for a household that's out all day with little evening load, still on a healthy feed-in tariff, where a battery wouldn't pay back inside its warranty yet — so the honest call is to wait. A verified, anonymised real case will replace this card, only with the customer's permission.
Buy smaller: a right-sized system that pays back better (example)
This is an illustrative example of the kind of advice we give — not a real customer. It stands in for someone who asked for a large system, where their genuine evening and daytime-surplus numbers pointed to a smaller one that pays back better and costs less up front — so we recommended smaller. A verified, anonymised real case will replace this card, only with the customer's permission.
Don't buy: the numbers won't pay off for this usage (example)
This is an illustrative example of the kind of advice we give — not a real customer. It stands in for a household whose usage pattern meant the system simply wouldn't earn back its cost within the warranty and throughput life — so the honest answer was "not this, not now". A verified, anonymised real case will replace this card, only with the customer's permission.
We publish real, anonymised cases here as they happen — with the customer's permission.
Ask us the question a seller won't answer.
Bring us your real usage and your bill, and ask us straight: should you buy at all? We'll give you one of four honest answers — go ahead, wait, buy smaller, or don't buy — and we'll tell you why.
The only way to know whether a system pays for your home is to run your actual numbers, not a brochure average — and to have someone willing to say "no" when the answer is no. That's the whole idea. If the maths already works, we'll say so and get on with it. If it doesn't, you'll hear "wait" or "smaller" — and you'll have saved money by asking. Either way, you can check how often our advice is to walk away on our public honesty record.
Saying no —
your questions, answered.
Yes. There are four honest 'no's we give: wait (when the timing, price or your roof means buying now would be a mistake), buy smaller (when a smaller system pays back better than the one you asked for), don't buy (when the numbers will not pay off for your usage), and go elsewhere (when another solution or supplier genuinely fits you better). We would rather lose a sale than sell you a system that will not pay off, because an installer who only ever says yes is not giving you advice — they are taking an order. It is also why our AI advisor, Jouli, publishes a live honesty record of how often its advice is to walk away from a purchase.
Because an installer who is paid only when you buy is structurally biased towards a yes, and the only way to be genuinely honest is to be willing to give up the sale. If we tell you to wait or buy smaller when that is the right call, you trust us with the purchase that does make sense — now or later — and you tell other people. Selling you a system that does not pay off costs us far more in the long run than the one sale is worth. The honest 'no' is not charity; it is how a trustworthy business is supposed to work.
Right now they are not — the cases on this page are clearly labelled examples that illustrate the kind of advice we give, not real customers. We will not invent a name, a suburb or a dollar figure and present it as a real person, because that would be exactly the dishonesty this page is meant to stand against. As real cases happen, we publish them here anonymised and only with the customer's permission, replacing the examples one by one. In the meantime, the honesty you can verify today is mechanical, not anecdotal: our AI advisor Jouli logs every time it steers a customer away from a purchase, and that walk-away rate is published live.
It means recommending a smaller system than you asked for — or than a salesperson would push — because a right-sized system often pays back better than a bigger one. A battery or solar array sized beyond your genuine usage has extra capacity that sits half-used and still has to be paid for, which lengthens payback rather than shortening it. The right size is set by your real evening and overnight usage and your daytime solar surplus, not by the biggest number on the brochure. 'Buy smaller' is one of the most common honest calls we make, and it usually saves you money up front and improves your return.
Waiting is the honest call when buying now would not pay off on your current situation: when a battery would not pay back within its warranty and throughput life on your usage, when you do not yet have solar or enough daytime surplus to charge a battery, when your feed-in tariff still pays you well for exported solar, or when your roof, switchboard or plans for the property mean the install should come after another job. Note that a rebate deadline on its own is not a good reason to rush — the federal Cheaper Home Batteries Program steps down gradually rather than ending in a cliff, so 'buy now before the rebate ends' is a sales line, not a reason. If the numbers already work for your home, we will say so; if they do not, we will tell you to wait.

Our AI energy advisor, Jouli, has a second AI critic — the Red Pencil — that audits every reply for the customer's benefit and logs it whenever the advice is to walk away from a purchase or is steered towards a Mission Green product. That page reads those logs live and publishes the walk-away rate, the steer-to-Mission-Green rate and the pass rate, so the honesty is something you can measure rather than something we simply claim. The examples on this page will become real, permission-based cases over time; the honesty record is verifiable right now.
