Facebook ads work for solar installers when you qualify leads before they reach you (homeowner, roof, postcode or zip code, energy bill), promote one clear offer such as a free savings estimate, and call back within minutes. If your ad promotes financing, in the US Meta requires a special ad category that limits your targeting, so plan for that.
Solar is one of the most advertised home improvements on Facebook, which means homeowners see plenty of ads and plenty of hype. The installers who do well are not the ones with the loudest claims. They are the ones who filter out people who can’t buy, give an honest estimate and follow up quickly and professionally.
What solar leads cost
Solar sits in the home improvement category, where WordStream’s 2026 US benchmarks put the median cost at $42.95 per lead and $2.18 per click. Solar is a competitive niche, so expect to pay at or above that in busy markets. What matters is the cost of an installed system, not the cost of a lead. If a system is worth $20,000 and you close 1 in 15 qualified leads, each qualified lead is worth over $1,300 on paper. Run your own numbers in the Facebook ads cost calculator.
Qualify before you pay a salesperson to call
The biggest waste in solar advertising is sales time spent on people who can’t go ahead. Ask a few short questions on your form or landing page:
- Do you own your home? Renters usually can’t install panels.
- What is your postcode or zip code? So you only take leads you can serve.
- Roughly how much is your monthly electricity bill? Bigger bills usually mean bigger savings.
- What type of roof do you have, and which way does it face? Optional, but useful for a first estimate.
Every extra question lowers the number of leads but raises their quality. For solar, a few good questions almost always pay for themselves. I explain the trade-off in lead ads vs landing pages.
Offers that work
- Free savings estimate: a personalised estimate based on their bill and roof. Concrete and useful.
- Home battery or solar-plus-battery check: for homeowners worried about rising bills or power cuts.
- Incentive check: where grants, tax credits or other schemes apply, offer to check what they qualify for. Only mention incentives you can confirm for your area, and never promise savings you can’t back up.
The financing ad rule you need to know
If your ad’s offer is a loan or financing plan, Meta may require you to use the Financial Products and Services special ad category. In the US that means you can’t target by age, gender or zip code, locations must include at least a 15-mile radius, and lookalike audiences are not allowed. If you want tighter targeting, lead with the savings estimate and discuss financing on the call instead.

Book a free callAd ideas that build trust
Use real installs on real local homes, a short video of a customer showing their app or bill, and your team on site. Avoid the “free solar” style claims that make people suspicious. Specific and honest beats loud.
Follow up fast, then keep following up
One widely cited study of around 15,000 leads found that contacting a lead within 5 minutes, rather than 30, made it roughly 21 times more likely to qualify. Solar leads are often talking to several companies, so the first professional reply has a big advantage. Send an instant text, offer booking times for the estimate, and remind them before the appointment. An AI appointment setter can book appointments in the evenings and at weekends when your office is closed. Solar decisions take time, so keep in touch with helpful follow-ups for weeks, not days.
Mistakes that waste solar ad spend
- No qualifying questions, so sales time goes on renters and people outside your area.
- Overpromising savings, which attracts the wrong people and damages trust.
- Ignoring the financing ad rules, which can get ads rejected.
- Slow callbacks. By the next day, many leads have already booked someone else.
- No tracking. Set up the Meta Pixel and Conversions API so Meta learns who becomes a qualified lead.
Frequently asked questions
Do Facebook ads work for solar installers?
Yes, when the form qualifies leads (homeowner, area, energy bill), the offer is clear and honest, and every lead gets a fast reply. Unqualified leads are the biggest waste in solar advertising.
How much do solar leads cost on Facebook?
Solar falls under home improvement, where WordStream’s 2026 US benchmarks put the median at $42.95 per lead. Competitive markets can cost more. Judge it on the cost per installed system.
Do solar financing ads need a special ad category?
If the ad promotes a loan or financing, Meta may require the Financial Products and Services category. In the US that removes age, gender and zip code targeting and requires at least a 15-mile radius.
What questions should a solar lead form ask?
Whether they own the home, their postcode or zip code, and roughly how much their monthly electricity bill is. Roof type and direction are useful extras.
