Meta Ads for Solar: Creating Demand Without Attracting Tyre-Kickers
On Meta you speak to people who are not searching for anything. That is both its strength and its risk: the contact costs less, and without a filter downstream the site survey costs far more.
Quick answer
Meta is for creating demand, Google for collecting it: on Meta you reach homeowners with usable roofs who are not searching for anything, so the cost per contact is lower but the leads are colder. The number to watch is not the cost of the contact, it is the cost per site survey carried out and per contract signed — a lead at half the price that produces half the surveys has saved nothing. The constraint that matters more than any targeting option is geographic: a contact a hundred kilometres away will never become an installation. The creatives that work are real installations completed nearby, with annual savings and payback years in place of slogans.
Meta and Google are not alternatives: they do two different jobs. Google intercepts people who have already decided to look into it and are comparing — we wrote about that in Google Ads for solar. Meta speaks to people who are not searching for anything, and that is simultaneously its value and its problem.
The value: volume is not capped by how many people happen to be searching in your province at that moment. The problem: none of them got up that morning thinking about solar.
Who to target, and what actually matters
The most elaborate targeting will not compensate for the most common mistake, which is geographic. The radius has to be kept tight around where you actually install: a lead a hundred kilometres away will never become an installation, but you paid for it all the same.
Inside that boundary the profile that matters is simple: owners of detached or semi-detached homes. Someone living in an apartment block or renting cannot decide alone, however interested they are. On top of that you can layer signals such as interest in energy saving or renovation, but those remain refinements compared with ownership and distance.
The number that misleads
Meta shows a lower cost per contact than Google, and that leads many installers to move their entire budget across. It is a misreading of the data.
A lead that costs half as much but becomes a site survey half as often has saved nothing — and in the meantime it has consumed a technician's time to reach the same conclusion. The comparison between the two channels is made on cost per signed contract, the only figure that accounts for everything happening after the click.
The full calculation, from cost of contact to cost of contract, is in cost per lead in solar.
Native form or landing page?
These are two choices with opposite consequences, and the answer depends on what you have downstream.
- Native form. It does not make the user leave the app, so it collects more contacts — and for the same reason it collects more tyre-kickers. Sustainable only if automatic qualification filters before the site survey.
- Landing page. It asks for one extra action and brings fewer leads, more serious on average. It protects your technicians' time when qualification is not yet automated.
In both cases you need the five data points that decide feasibility — property type, surface, annual consumption, existing system, urgency. Without them, every contact looks like every other until somebody phones them.
The creatives that work
In solar the creative has one precise job: to let the reader recognise their own situation. What works is real installations completed in the area, on roofs similar to the viewer's. Stock photos with generic panels and blue skies are recognisable at a glance, and they communicate that you have no installations of your own to show.
In the copy, numbers beat adjectives: annual savings on the bill and years to payback say something verifiable, "the best solution for your home" does not. And in 2026 there is a real deadline to use without alarmism, since under current Italian law the rates drop from 2027 — and the 65% being discussed concerns the ecobonus, not photovoltaic.
In summary
Meta creates demand, Google collects it, and you need both. Tight geographic radius, owners of detached homes, automatic qualification downstream because the contact arrives cold, creatives with real installations and concrete numbers. And the verdict on the channel is given on cost per contract, never on cost per contact.
