Why Solar is an independent guide to solar and batteries for Australian homeowners, run by two people who live off-grid on their own system. We are not an installer, and no installer or energy retailer owns a piece of us.
Ask why before you sign.
We set out to power our own home with the sun. We did our homework, we trusted the installer who seemed different from the rest, and we paid close to $100,000. We were charged for German batteries and handed cheap knock-offs. The system couldn't get through a normal week, and we spent five years putting it right.
So we built Why Solar. We don't sell solar. We vet the installers, we match you with one, and we tell you the truth even when it earns us nothing.
Andy McMaster, founder
We don't have a grid connection. Our home, our office and this website are built and run from a property that is 100% solar and battery powered. When our system underperforms, our lights go out. So we learned what works, what fails, and which installers stand behind their work, because we had to.
That's the difference between advice from someone who sells solar and advice from someone who depends on it.
Your postcode and a few questions. We work out the federal and state rebates for your home. No account, no sales call.
One installer who has passed all six of our checks, and one written quote. They never cold-call you.
Fifteen minutes with a solar expert, at a time you choose: the size, the rebate and your quote, line by line.
A warranty is only as good as the company behind it. Before an installer earns Why Solar approval, they pass every one of these. Most don't.
“We hold installers responsible for what they promise. If they won't be, they don't get our homeowners.”
Accreditation and licensing, current and genuine, checked rather than assumed.
Years actually trading, and the financial stability to still be here in a decade to honour what they promise.
Real installations we can examine, not a folder of stock photos and slogans.
Who physically turns up to do the job, not the cheapest available subcontractor.
Genuine, traceable components that match the quote exactly. No quoting German and fitting Chinese.
How they behave when something goes wrong. That, not the sales call, is the true measure of a company.
