Tw solar companies operate in the same suburb of Newcastle. They quote the same panels, the same inverter, roughly the same price. One has a hundred and forty Google reviews at 4.9 stars with a fresh one every week. The other has 19 reviews, the newest from eleven months ago. When a homeowner runs three quotes and then types the company names into Google, you already know who wins the call back.
That gap is not about installation quality. Both crews do good work. The difference is that one company treats reviews as a system and the other treats them as something that happens by accident. In a market where the average residential job sits between eight thousand and fourteen thousand dollars and buyers almost always collect multiple quotes, the review profile is doing the silent pre-qualification before a salesperson ever speaks.
This guide is the operating system. Not platitudes but the exact mechanics: how many reviews you need, when to ask, how to automate it, what is legal under Australian law, how to handle the bad ones, and how to measure the lift. It is written for solar business owners and marketers, not for homeowners.
Google reviews are the cheapest, highest-leverage lead source a solar installer has, because they compound across four channels at once: they lift your map pack ranking for local searches, they raise click-through on your Google Ads, they convert visitors on your website, and they feed the AI tools buyers increasingly use to shortlist installers. The winning move is not buying or filtering reviews, which breaches Google policy and ACCC law, but building a simple post-commissioning system that asks every customer, makes leaving a review effortless, and responds to all of them.
TL;DR:
Reviews compound for solar because it is a high-trust, high-ticket, multi-quote purchase. Aim to out-volume and out-fresh your top local competitor, not just clear an arbitrary number. Ask every customer at the moment of delight (a few days after commissioning) using an automated SMS or email with a direct review link. Never gate reviews by happiness or rating first, because that breaches Google policy and the ACCC stance on misleading testimonials. Respond to every review, handle negatives calmly, report genuinely fake ones, and reuse real reviews compliantly in ads and on landing pages. Then measure the lift in calls, map views and conversion.
Why do reviews compound harder for solar than almost any other trade?
Most local businesses benefit from reviews. Solar benefits disproportionately, and it is worth understanding why before you spend a dollar building the system. The economics of the purchase amplify every star.
First, solar is a high-ticket, once-in-a-decade decision. A homeowner is committing thousands of dollars to equipment bolted to their roof for twenty-five years, often financed. That level of risk makes social proof do heavy lifting, because the buyer cannot easily judge component quality. Reviews become the proxy for trust they cannot otherwise verify.
Second, the category is plagued by horror stories. Years of phoenix companies, dodgy door-knockers and warranties that evaporated when the installer folded have left Australian solar buyers unusually suspicious. The Clean Energy Regulator and the Clean Energy Council both warn about operators who disappear. A wall of recent, detailed reviews is the fastest way to signal you are not one of them.
Third, solar buyers almost never buy on the first quote. They collect two to four, sit on them, talk to a partner, then re-research the shortlist. That re-research step is where reviews win or lose the job, because the buyer is now comparing companies side by side on the one signal that is hardest to fake at scale.
Fourth, reviews feed everything else you are already paying for. They lift your position in the local map pack, which we cover in our guide to local SEO for solar installers. They raise the click-through rate on your Google Ads via seller ratings. And they are increasingly quoted by AI assistants when someone asks for a recommendation, which is exactly why we wrote about answer engine optimisation for solar companies.
How many Google reviews do you actually need, and how fresh?
The honest answer is that there is no universal number. The right target is relative: you need to out-volume and out-fresh the installers you actually compete with in your service area, not hit a figure you read in a generic blog. A company fighting for jobs across Western Sydney needs a very different profile to one serving a regional town.
The two metrics that matter are volume (total reviews and rating) and velocity (how many fresh reviews arrive per month). Velocity is the one most installers ignore, and it is arguably more important. A profile with two hundred reviews where the newest is eight months old reads as a business gone quiet. Twelve fresh reviews in the last ninety days reads as a business busy and trusted right now.
Recency affects ranking and buyer psychology together. Google notes in its Business Profile help documentation that review recency and frequency are signals it considers, and buyers plainly trust a review from last week over one from 2023. The practical rule: a steady trickle beats an occasional flood.
To make this concrete, here is a realistic monthly velocity target by installer size and metro competitiveness. Treat it as a floor, not a ceiling.
| Installer profile | Installs / month | Target new reviews / month | Healthy rating |
|---|---|---|---|
| Owner-operator, regional town | 8 to 15 | 4 to 7 | 4.7+ |
| Small team, secondary city (e.g. Geelong, Townsville) | 15 to 30 | 8 to 14 | 4.8+ |
| Established mid-size, capital metro (Brisbane, Perth) | 30 to 60 | 15 to 28 | 4.8+ |
| Multi-crew, hyper-competitive metro (Sydney, Melbourne) | 60+ | 28 to 45 | 4.9 |
Notice the conversion rate baked in. Even a good system rarely converts more than forty to fifty per cent of customers into reviewers, so a company doing thirty installs a month that wants fourteen reviews needs to ask all thirty. That is the whole game: ask everyone, make it easy, follow up once.
When in the install journey should you ask for the review?
Timing is the lever most installers get wrong. Ask too early and the customer has nothing to say. Ask too late and the emotional high is gone. The window you want is the moment of delight, which for solar is not the day of installation. It is a few days after commissioning, once the system is switched on and the customer has watched their meter start to spin backwards or seen the app show generation for the first time.
The day of installation is busy and slightly stressful. There are crews on the roof, paperwork, and the customer is often at work. By contrast, three to five days post-commissioning the customer has had their first sunny day, checked the monitoring app, and felt the small thrill of free electricity. That is when they will write something specific and enthusiastic.
Map your ask to the customer journey deliberately. There are two strong ask points: the post-commissioning glow, and again after the first reduced electricity bill arrives. The second produces the most powerful reviews because the customer now has a dollar figure to quote. Someone who writes “my bill dropped from four hundred and twenty dollars to ninety dollars” is doing your sales copy for you, and that specificity is exactly what other buyers and AI tools latch onto.
How do you operationalise the ask so it is not on your memory?
If asking for reviews depends on a busy installer or office manager remembering to do it, it will not happen consistently. The fix is to make the request part of your job-completion workflow so it fires automatically, the same way an invoice does. This is the difference between a few stray reviews and a predictable monthly velocity.
The mechanics are simple and cheap. When a job hits “commissioned” status in your CRM or job tool (ServiceM8, simPRO and similar all support this), trigger a delayed automation: an SMS three to five days later, and an email backup a few days after if no review has landed. The SMS does the heavy lifting because texts get opened, and the email gives room for a clearer link.
The single most important asset is your direct review link. Inside your Google Business Profile you can generate a short link that drops the customer straight onto the “write a review” screen with the star selector open. Do not send people to “search for us on Google”, because every extra step bleeds completion. Turn that link into a branded short URL and a QR code.
Use the QR code everywhere the customer physically interacts with you: on the handover folder, on a sticker beside the inverter or on the meter board, on the final invoice, and on a small card the crew leaves behind. The QR plus a one-line script (“If you’re happy with the install, a quick Google review really helps a small local business”) closes the loop in person while the SMS catches everyone else.
Here is a deployment checklist for the system:
- Generate your Google Business Profile direct review short link.
- Create a branded short URL and a printable QR code from it.
- Build a CRM automation that fires on “commissioned” status: SMS at day three to five, email at day seven to ten if no review.
- Add the QR to handover folders, inverter stickers, final invoices and crew leave-behind cards.
- Write a 25-word SMS script and a slightly longer email script (examples below).
- Set a calendar reminder to check velocity monthly against your competitor benchmark.
Why is review-gating illegal in Australia, and what do you do instead?
This is the section that keeps installers out of trouble, so read it twice. Review-gating means screening customers by satisfaction or star rating before you let them leave a public review. The classic version is a survey that asks “how was your experience?” and only routes the happy ones to Google while diverting unhappy ones to a private feedback form. Some tools market this as “review funnelling” or “reputation protection”. It is against the rules on two fronts.
First, it breaches Google’s own policy. Google explicitly prohibits “review gating”, the practice of selectively soliciting positive reviews while discouraging negative ones, in its Business Profile content policies. Profiles caught doing it can have reviews removed or face other action. You are building your most valuable asset on rented land, so do not violate the landlord’s rules.
Second, and more seriously, it runs against Australian Consumer Law. The ACCC treats reviews as testimonials and has been explicit that manipulating them, including selectively publishing only favourable feedback or suppressing genuine negative reviews, can be misleading or deceptive conduct. The ACCC has taken enforcement action over fake and manipulated reviews, and its guidance is clear that a curated review profile that misrepresents overall sentiment can mislead consumers. Penalties for breaches of the misleading conduct provisions run into the millions.
So what do you do instead? You ask every customer, full stop. Not just the ones you think are happy. This feels counterintuitive to a nervous owner, but it is both the legal path and, in practice, the better-converting one. A profile that is exclusively five stars looks suspicious; a 4.8 with a few thoughtful three-star reviews and good responses reads as authentic and is more persuasive. A negative review you respond to well is itself a marketing asset, because it shows future buyers how you behave when something goes wrong, and asking everyone also surfaces problems early while you can still fix them. None of this means tolerating fake reviews, which we deal with below.
How should you respond to every review, including the brutal ones?
Responding to reviews is not optional housekeeping. It is a ranking and conversion activity. Google’s documentation encourages owner responses, future buyers read your responses as closely as the reviews themselves, and a consistent reply habit signals an engaged business. The rule is simple: respond to every review, positive and negative, ideally within forty-eight hours.
For positive reviews, keep it short, specific and human. Thank them, reference a detail (“glad the battery sizing worked out for your Toowoomba place”), and avoid copy-pasting the same line. Identical replies look automated and waste the chance to add a keyword or warm note the next reader will see.
For negative reviews, you need a framework, because the instinct to argue is strong and almost always wrong. Use this four-step approach, often shortened to the acronym of acknowledge, apologise, act, offline:
- Acknowledge the specific issue without being defensive. “Thanks for flagging the delay on your meter reconfiguration.”
- Apologise for the experience, even if you dispute some facts. You are writing for the thousand future readers, not just this one customer.
- Act by stating what you will do or have done. “We’ve reviewed the scheduling that caused this and we’re sorry it slipped.”
- Offline the rest. Give a direct phone number or email and move the detailed back-and-forth out of public view.
Never disclose private customer details in a response, even to defend yourself. Beyond being poor form, revealing personal information without consent can run into privacy obligations the OAIC oversees. Stay calm, stay brief, stay professional, and let the contrast between an angry reviewer and your measured reply do the persuading.
One more discipline: when you genuinely fix the problem, you can politely ask whether the customer would consider updating their review. Many will. You cannot demand it or offer an incentive, but a sincere “we’d love the chance to earn a better experience” after a real resolution is fair game and often works.
What about fake reviews and competitors attacking your profile?
Sooner or later a solar installer with a busy profile gets hit by something that is not a real customer: a one-star with no text, a review from someone you have no record of, or a suspiciously detailed hit-piece that lines up with a competitor’s launch. You cannot delete reviews yourself, but you are not powerless.
Start by checking your own records. If you genuinely cannot match the reviewer to any quote, site visit or job, that is your evidence base for a removal request. Respond publicly first, calmly and on the record: “We’ve checked our system and have no record of a job or quote under this name. If you believe we’ve made an error, please contact us at [number] so we can help.” This protects you with future readers even if the review stays up.
Then report it through Google. Use the flag function in your Business Profile and, for stubborn cases, the dedicated review-removal request flow for content that breaches its policies (fake engagement, conflicts of interest, off-topic content). Removal is not guaranteed and can be slow, so the public response is your first line of defence.
If a pattern of coordinated fake reviews appears to come from a competitor, that crosses into Australian Consumer Law territory. Both posting fake reviews and orchestrating attacks on a rival can be misleading and deceptive conduct, and the ACCC has pursued businesses over exactly this, so keep dated screenshots. And to be explicit: you must never write fake reviews yourself, pay for reviews, or buy review packages, regardless of what a competitor does. It is illegal, it is detectable, and it puts your whole profile at risk.
How do you reuse reviews in ads, on landing pages and in sales, legally?
A review’s job does not end on your Google profile. Real reviews are some of the highest-converting content you own, and you should put them to work everywhere a buyer makes a decision. The catch is that the same ACCC testimonial rules apply: anything you publish must be genuine, attributable and not misleading.
On your website, lift real review quotes onto your service pages, especially the solar landing pages buyers see after clicking an ad. A specific quote (“bill went from four hundred and ten dollars to eighty dollars in the first quarter, Coffs Harbour”) next to a call-to-action lifts conversion more than any amount of hero copy. We go deeper on this in our guides to landing page optimisation and improving your website conversion rate, and it is core to building a solar website that converts.
In Google Ads, your aggregate star rating can appear as seller ratings and location extensions pull your profile reviews into the ad itself, lifting click-through at no extra cost per click. Just make sure any review claims in ad copy are accurate, current and compliant with both Google’s policies and the solar-specific advertising rules we cover in CEC and ACCC compliance for solar ads.
The compliance guardrails for reusing reviews are straightforward. Use real, verifiable reviews only. Do not edit a quote in a way that changes its meaning or strips important context. Do not cherry-pick to imply a flawless record that your actual profile contradicts. Do not present a single glowing review as if it were typical if it is not. The ACCC’s position on testimonials is that they must reflect genuine experience and not create a misleading overall impression. Used honestly, your reviews are a compliant conversion engine; used deceptively, they are a liability.
How do you turn reviewers into referrers, and measure the whole thing?
A customer who just left you a five-star review is at peak goodwill. That is the moment to invite a referral, not six months later in a cold email. Build it into the thank-you: after acknowledging their review, add a soft line such as “if you know a neighbour weighing up solar, we’d love an introduction”. Referrals from a freshly delighted customer are the cheapest qualified leads in the business, which ties directly into the themes in our solar lead generation guide.
Referred leads also tend to be higher quality, because they arrive pre-trusted and less price-shoppy than a cold form fill. We make the case for why this matters more than raw volume in solar lead quality versus quantity. A review system and a referral system are really one system pointed at the same happy moment.
Now measure it, because an investment you cannot see the return on gets cut first. You do not need fancy attribution. Track four numbers monthly: new reviews and average rating, profile views and calls from your Business Profile insights, your map-pack position for core “[suburb] solar installer” terms, and conversion rate on the landing pages where you display reviews.
What we have seen. Across solar clients where we have implemented an automated post-commissioning ask paired with response discipline, the pattern is consistent. Monthly review velocity has typically risen two to four times within a quarter once the SMS automation goes live. Clients that lifted from the mid-to-high four-star range and, more importantly, from stale to fresh, have generally seen Business Profile calls and direction requests climb by roughly twenty-five to fifty per cent over three to six months. On landing pages where genuine review quotes sit beside the enquiry form, we have seen conversion rates improve by mid-single to low-double-digit percentages. These are ranges across multiple accounts, not guarantees, and results depend on install volume, service quality and competitive density.
If you want help wiring the automation, the responses and the on-site display into a single system, that is exactly the kind of work our SEO and solar marketing teams build for installers. Reviews are also one of the clearest ways to stand out when your panels and prices look like everyone else’s.
Frequently asked questions
How many Google reviews does a solar installer really need?
There is no fixed number. The target is relative: aim for more total reviews, a stronger rating (4.8 or higher in competitive metros) and fresher reviews than the installers you actually compete with in your service area. In Sydney or Melbourne that can mean a hundred or more reviews with twenty-plus arriving monthly, while a regional owner-operator may compete well with forty to sixty reviews and four to seven fresh ones a month. Velocity matters as much as the total.
Is it legal to only ask happy customers for reviews?
No. Screening customers by satisfaction and only routing the happy ones to Google, known as review-gating, breaches Google’s Business Profile policies and can amount to misleading or deceptive conduct under Australian Consumer Law as enforced by the ACCC. You should ask every customer, regardless of how you think they feel, and let genuine sentiment land. It is both the compliant path and, in practice, more persuasive to buyers because a profile with a few honest critical reviews and good responses reads as authentic.
When is the best time to ask a solar customer for a review?
Around three to five days after commissioning, once the system is switched on and the customer has seen generation in their monitoring app. The day of installation is too busy and stressful to produce a thoughtful review. A second strong moment is after the first reduced electricity bill arrives, because the customer can then quote a real dollar saving, which makes the review far more persuasive to future buyers.
How do I get the direct Google review link for my business?
Inside your Google Business Profile you can generate a short link that takes customers straight to the “write a review” screen with the star selector ready. Turn that link into a branded short URL and a QR code, then put it in your post-commissioning SMS and email, on inverter stickers, on final invoices and on a leave-behind card. Never make customers search for you manually, because every extra step loses reviews.
How should I respond to a negative or unfair solar review?
Respond within about forty-eight hours, calmly and publicly, using acknowledge, apologise, act and take it offline. Acknowledge the specific issue, apologise for the experience, state what you will do about it, then offer a direct phone number or email to continue privately. Never argue, never disclose the customer’s private details, and remember you are writing for the many future readers, not just the upset reviewer. A measured response to a complaint often converts more readers than a wall of perfect five-star reviews.
Can I get a fake or competitor review removed?
You cannot delete reviews yourself, but you can flag and report ones that breach Google’s policies, such as fake engagement, conflicts of interest or off-topic content, through your Business Profile and Google’s review-removal request flow. First respond publicly and calmly, noting you have no record of the customer in your system. Keep dated screenshots, because coordinated fake reviews from a competitor can be misleading and deceptive conduct that the ACCC pursues. You must never retaliate by posting fake reviews of your own.
Can I use my Google reviews in ads and on my website?
Yes, provided they are genuine, accurately quoted and not misleading. You can display real review quotes on landing and service pages, and Google Ads can show your aggregate seller rating. The ACCC’s testimonial rules require that any review you publish reflects a real experience and does not create a false overall impression, so do not edit quotes to change their meaning, cherry-pick to hide your record, or fabricate anything. Used honestly, reviews are a strong, compliant conversion tool.
Is it ever okay to buy reviews or offer a discount for one?
No. Buying reviews, posting fake ones or offering an incentive in exchange for a review all breach Google’s policies and can be illegal misleading conduct under Australian Consumer Law. The ACCC has taken enforcement action over fake and incentivised reviews, with penalties running into the millions. You can ask every customer and make leaving a review easy, and after genuinely fixing a problem you can politely ask a customer to reconsider their review, but you can never pay for, incentivise or fake one.
