Why Meta, of all companies, for a solar power system?
The first objection is bound to come up: “People on Instagram aren’t looking for solar power systems.”
That's right. And that's exactly where the difference from Google lies. With Google, you reach people who have already decided they want a system. These people are expensive because everyone is competing for them, and there aren't many of them.
On Meta, you'll find the much larger group that comes before that: people who've been thinking about it for two years, getting annoyed by their electricity bills, and never had a reason to get started. You need to stimulate this demand rather than just capture it. It's more work, but the competition there is a fraction of what it is elsewhere.
The two are not mutually exclusive. If you have a budget for only one channel and are already running ads on Google, you should stick with it. If you want to grow and have exhausted search demand in your region, Meta offers the next opportunity for growth.
The Mistake That Wipes Out Most Budgets
The most common ad in this industry features a photo of a completed solar system on a roof, with the caption “Switch to solar now” above it and “Free consultation” below it.
This ad doesn't work, and there's only one reason why: It's no different from the forty others that the same person has seen this week. A roof with solar panels isn't an image—it's a category.
What has worked in our projects, on the other hand, is unspectacular—and therefore striking: the face of the person who comes in for a consultation. A rough-cut montage with visible scaffolding. A cell phone video of the boss explaining in thirty seconds why a storage unit isn’t cost-effective for some households.
The reason isn't aesthetics. A high-gloss look resembles an ad, and people scroll past ads. Something that looks like a post from a real person gets read.
What You Need to Measure Before You Start
The biggest difference between campaigns that work and those that just cost money isn't the ad itself. It's whether Meta finds out what happened with a lead.
Anyone who simply reports back “Request sent” is optimizing for forms. The algorithm then reliably delivers exactly that: lots of low-cost requests from people who rent or own a 30-square-meter attic in the Northeast.
That's why you need at least two responses:
We have received a request, which is the basis for being able to optimize anything at all.
The inquiry met the criteria—that is, the owner, a suitable roof, a realistic budget—and a date was set.
The second follow-up isn’t automatic. Someone on your team has to set it up after the initial conversation. That takes two minutes per inquiry, and it’s the difference between 60 euros per pointless contact and 200 euros per genuine prospect. To let Meta know, your CRM sends the classification via the Conversions API. Currently, Meta can only optimize this for lead forms directly on Facebook or Instagram and for volumes of around 200 inquiries per month or more; for lower volumes, it primarily helps with analysis. The second number sounds worse but is actually much better.
Target Audiences: Set Fewer Than You Think
Anyone who has developed the habit in recent years of piling up interests—such as “solar power,” “sustainability,” “home ownership,” and “energy conservation”—is working against the system.
Which is more durable in practice:
A tight radius around your service area. This is the most important setting of all. Anyone who can’t travel to your location is of no use as a potential customer. Anyone advertising financing or installment payments in their listing must label them as a financial product. In that case, a radius of at least 15 kilometers applies, and age and other criteria can only be set to a limited extent.
Age 30 and older. There are fewer homeowners in this age group. However, with the default "Advantage+" target audience setting, the maximum age limit is 25; Meta treats any age above that as a suggestion only.
Otherwise, keep it to a minimum. The algorithm finds the right people based on the responses to your ad faster than you can describe them by checking boxes—provided you let it know which requests were worthwhile.
There’s one special case that’s almost always worth targeting: people who have visited your website but haven’t submitted an inquiry. This group is small, inexpensive to target, and is usually the most likely to make a purchase. However, it can only be tracked using the meta pixel, which may only be used for visitors who have given their consent via the cookie banner. As a result, this group is smaller than the visitor numbers might suggest.
Form or landing page?
Meta offers forms that open directly in the app and often have the contact information already filled in. This generates a lot of inquiries, many of which come from people who don't remember anything two days later.
A dedicated landing page generates fewer inquiries, but each one captures the prospect's attention. They've read about who you are and deliberately clicked "Send."
Our experience: Direct forms are a good choice if you need volume and have a sales team that follows up quickly and persistently. Without that team, a landing page is the better option, because the few inquiries you receive will actually turn into appointments.
When you use direct response forms, speed is everything. Someone who calls within ten minutes reaches significantly more people than someone who doesn't call back until two days later.
How long it takes to get a reliable result
Expect it to take four to six weeks before the numbers are reliable. At first, the system is learning, and the costs look bad. According to Meta, this learning phase usually ends after about 50 results within a week of the last significant change. With small budgets, this number is often not reached, in which case the Ads Manager displays “Learning phase limited.” If you pause your campaign at that point, you’ve just paid and learned nothing.
When it comes to the budget, the math is simple: If a qualified lead costs you roughly 150 to 250 euros and you want to gain insights from a usable contact each month, an advertising budget of less than 1,500 euros per month hardly makes sense. Even with 1,500 euros, at 150 to 250 euros per qualified inquiry, you’ll only get six to ten such inquiries per month. That’s not enough to optimize for them. Therefore, optimization is based on incoming inquiries, and the qualified ones are primarily used for analysis. With a smaller budget, you won’t even have enough data for that.
In our article “Meta Ads 2026: What Advertising on Facebook and Instagram Really Costs,” we use data from managed accounts to show the total cost of a managed Meta Ads campaign and the minimum campaign budget at which it becomes cost-effective.
A Quick List of Things That Burn Money
Ads that lead to the home page instead of a page about the advertised topic.
The same two images for months on end. The target audience within a 30-kilometer radius is small and will eventually know them by heart.
Make adjustments to your campaigns every few days. Major changes to the budget, target audience, ads, or bids can reset the learning phase.
Collect inquiries without letting them know which ones were worthwhile.
Reach as a goal. It doesn't cost much, but Meta shows the ad to as many people as possible—not just those who are likely to make an inquiry.
Conclusion
Meta works for solar businesses, but not as a surefire success and not as a purely advertising channel. It works when the ad looks like it’s from a real person rather than a campaign, when there’s a website behind it that lives up to the promise, and when you provide feedback to the system about which inquiries actually helped you move forward.
The third step is where most people give up. It's also the one that determines the outcome.

Do you want to have that set up?
We handle campaigns, creative assets, and landing pages as a single package because these three elements are interdependent. You can find details on the cost and process on our Ad Management page.
