The solar industry has a trust problem. Every week, homeowners across Australia get burned by installers who promise the world, take a big deposit, and then either disappear or deliver something completely different from what was sold.
In this episode of Off The Grid, Jason and Cam from Source Energy Group sit down with Braden — a client and former technical service and warranty supervisor for one of Australia’s largest building companies — to break down the exact red flags to watch for before you sign anything.
Red Flag #1: A Large Upfront Deposit
If a solar company is asking for 50% upfront, that’s a serious warning sign. A quality install typically takes 7–14 days from sign-up to completion. Any company with proper trade accounts and financial backing doesn’t need half your money before they’ve lifted a finger.
What’s actually happening when they ask for 50%? In many cases, they’re using your deposit to pay off a previous job. Their trade accounts are maxed. They’re chasing their tail. And when the business eventually collapses — and 30% of solar businesses go under in the first two years — you’re last in line to get anything back.
Red Flag #2: They Sell 20 Different Products
A company that offers you a dozen panel brands and battery options isn’t giving you choice — they’re covering the fact that they don’t specialise in anything. They’ll sell whatever’s cheapest on the day.
A genuine installer backs specific products because they know them inside out. They understand the warranty backup chain. They know exactly how the equipment behaves over time. When something goes wrong in year 8, they can actually help — because they installed the same thing a hundred times before.
At Source Energy Group, we don’t budge on our product selection. We offer a workmanship warranty because we’re confident in what we install. If a customer wants a different product, they may need to go elsewhere — and we say that directly.
Red Flag #3: No Pre-Site Inspection
This is one of the most common failure points in the industry. A salesperson quotes you over the phone based on an aerial image that might be from 2016. Install day comes, the crew shows up, and suddenly you’re getting 20 panels instead of the 30 you were sold.
Every roof looks the same from above. It doesn’t tell you about the switchboard condition, whether tiles have been replaced, what’s shading the north face, or whether the roof can structurally handle the load. You only know that by going to site.
Before any Source Energy Group install, one of our experienced team members goes out to create a proper install plan. It makes the job smoother, faster, and means there are no surprises when the crew arrives.
Red Flag #4: Overseas Call Centres
If an Australian solar company is routing its sales calls through an overseas call centre, ask yourself: where else are they cutting costs? If they’re skimping on the customer conversation, they’re almost certainly skimping somewhere in the install.
Local knowledge matters in solar. Tariff structures, grid connection requirements, council regulations, and roof types vary across Queensland. You want someone who understands your market, not someone reading from a script in another time zone.
Red Flag #5: Reviews That Only Praise the Sale
Pay attention to what reviews actually say — not just the star rating. A pattern of reviews praising the salesperson and office staff, followed by complaints about install delays, product changes, or post-install disappearance, tells you exactly what to expect.
Braden’s review of Source Energy Group after his install was straightforward: the system eliminated his grid usage entirely. He now pays only the supply charge — roughly $120 a quarter — down from a $980 quarterly bill. That’s not a review of a sales process. That’s a review of an outcome.
Red Flag #6: Broken Tiles That “Didn’t Happen”
Any installer who claims they’ve never broken a roof tile is either not telling the truth or hiding them. Tiles break when you work on a roof — that’s the reality of the job. A professional installer asks upfront whether you have spare tiles, sources them beforehand if not, and is transparent when one breaks.
The dodgy version: silicon over the crack, hide it under a panel, and hope it doesn’t leak until after the warranty period. Braden saw plenty of this in his previous role — tubes of silicon used as a substitute for proper waterproofing. It causes more damage over time, not less.
The Real Question: Price vs Cost
There will always be cheaper quotes. The low end of the market — overseas multinationals shipping container loads of generic panels, contracting out random installers with no uniforms — can offer prices that look attractive on paper.
But what’s the cost when something goes wrong and the company is gone? When you call and the number’s disconnected? When the next installer won’t touch someone else’s work without charging you a full site visit fee?
Price is what you pay today. Cost is what you pay over 25 years.
What a Legitimate Install Actually Looks Like
When the Source Energy Group crew showed up at Braden’s house, they knocked on the door, introduced themselves, wore uniforms, and explained exactly what they were doing. A pre-site inspection had already been done. The install plan was set. No surprises.
When Braden’s internet tech later switched off his modem and the solar system went offline, our monitoring picked it up almost immediately — and someone from our local office called him to let him know what was happening.
That’s what post-install support looks like when a company is built for longevity rather than just the sale.
The Checklist Before You Sign
- Are they asking for more than a small holding deposit? (Red flag if 50%+)
- Do they specialise in specific products, or are they offering everything under the sun?
- Will someone come to site before install day — or is it all done over the phone?
- Are you dealing with a local Australian team or an overseas call centre?
- What do the reviews actually say — about the install and the aftercare, not just the sale?
- Do they ask about your spare tiles?
- Can they tell you specifically how the system will perform for your home, based on your actual usage data?
Solar works. The technology is proven. The savings are real. The only question is whether the company you choose will still be around — and still be answering the phone — in year 10, year 15, year 25.
Choose accordingly.
