Social media marketing for solar companies: real installs, honest savings posts, and the rules on testimonials, referral rewards and finance offers

Social media marketing for a solar company works when it proves three things a buyer worries about: that you install well, that the savings you describe are real, and that you will still answer the phone in five years. Post real installations from your own crews, customer stories with the numbers explained, monitoring results, and plain answers to the questions buyers ask about cost, roofs and batteries. Four sets of rules shape what those posts may say in the US. A customer's savings story is treated as a claim about typical results. A referral reward is a connection that must be disclosed. A post that quotes a loan payment brings in Regulation Z's advertising rule, and Meta requires its financial products and services category for such ads. And the federal residential solar tax credit is not available for systems placed in service after 31 December 2025, so posts must not offer it.

What to post

Solar is a large, considered purchase, and buyers often watch an installer for a while before they ask for a quote. Content that builds trust over that period works better than repeated offers.

• Install days. Short videos of your crew on a roof, the inverter and battery going in, a time-lapse of a full day. They show care and real people.
• Customer stories. The household, the roof, the system size, what they wanted and what they got, with their written permission.
• Monitoring results. A screenshot of a system's production over a month or a season, with the system size stated.
• Plain answers. Will my roof work? What happens in a power cut? Do I need a battery? What maintenance is needed? One question per post.
• Your people. Electricians, designers, the service team. Buyers want to know who will turn up.
• Service after the sale. A panel cleaned, a fault fixed, a warranty claim handled. This answers the five-year question directly.

Which platforms fit which buyer

Platform	Buyer	What works there
Facebook	Homeowners in your service area	Customer stories, local installs, answers to questions, community groups where promotion is allowed
Instagram	Homeowners, especially for design-led installs and batteries	Install videos, finished roofs, behind the scenes
YouTube	Buyers researching in depth	Longer explainers: how a system is sized, what an inspection involves, battery choices
LinkedIn	Commercial, farm and public sector buyers	Commercial projects, production data, the business case explained

A residential installer can do well with Facebook and Instagram alone. Add LinkedIn if commercial work is part of the plan.

Savings posts and customer testimonials

The most persuasive solar post is a customer saying their bill fell. It is also the post with the most rules attached. Under the FTC's Endorsement Guides, a consumer endorsement about a central attribute of a product "will likely be interpreted as representing that the endorser's experience is representative of what consumers will generally achieve" (16 CFR 255.2(b)). If the customer's result is better than what most of your customers get, the post should clearly state the generally expected result, and you need evidence for that figure too.

In practice:

• State the system size, the location and the period behind any savings figure.
• Do not present one exceptional bill as normal. If a household's bill fell to zero in a sunny month, say it was one month.
• Keep your own records behind every number you post, because the endorsement rules require you to have substantiation as if you made the claim yourself (16 CFR 255.2(a)).
• Get written permission from the customer before naming them or showing their home.

Referral rewards and paid creators

Referral programmes suit solar well, because happy owners talk to their neighbours. They also create what the FTC calls a material connection. The Endorsement Guides say a connection that might affect how much weight people give an endorsement, and that the audience would not expect, must be disclosed clearly and conspicuously, and that payment or free or discounted products count even if no endorsement was required in return (16 CFR 255.5). So a customer who posts about you while earning a referral fee should say so, and so should a local creator you paid or gave a discount to. Give referrers simple wording to use.

Do not buy followers, likes or views. The FTC's rule on consumer reviews and testimonials makes it unlawful to buy fake indicators of social media influence that misrepresent your importance for a commercial purpose (16 CFR 465.8).

Finance offers, monthly payments and the tax credit

Monthly payment posts

"Go solar for $X a month" is a credit advertisement. Under Regulation Z (12 CFR 1026.24(d)), stating the amount of any payment, the number of payments, the down payment or the finance charge is a triggering term. Once one appears, the ad must also state the down payment, the terms of repayment and the annual percentage rate, using that term. Ask your finance partner to approve any post that mentions a payment, and keep the approved wording for reuse.

Paid ads on Facebook and Instagram

Meta's Special Ad Categories page says that since 21 January 2025, advertisers based in the US or showing ads to US audiences must use the financial products and services category for ads that promote or directly link to a financial products and services offer, including credit. A solar ad that promotes or links to a loan offer falls into that category. For these ads, Meta says age, gender, ZIP or postal code, exclusion targeting, lookalike audiences and saved audiences are limited or unavailable, so plan the audience by city or radius instead.

The federal tax credit

The IRS states that the Residential Clean Energy Credit "is not available for any property placed in service after December 31, 2025". Old posts and pinned highlights that promise homeowners a 30% federal credit are now wrong. Review your profiles and pinned posts, and talk about the incentives that still apply in your area, with a date on any figure.

Environmental claims in a caption

The FTC's Green Guides apply to social posts as much as to websites. Specific claims, such as the system's expected annual production, are easier to support than general ones like "eco-friendly" or "zero impact". If your company sells the renewable energy certificates from its own panels, it should not post that its office runs on renewable power (16 CFR 260.15(d)). Our page on SEO for solar companies covers these claims in more depth, along with incentive pages that stay accurate.

What to measure

Likes do not install panels. Track quote requests and site surveys that came from social media, by asking every lead how they found you and by using tracked links in your profile. Watch which posts lead to messages, and which questions buyers ask most, then answer those questions in the next posts. For referral programmes, count referred installs, not referral links shared.

Questions about social media marketing for solar companies

What should a solar company post on social media?

Real installs by your own crew, customer stories with system size and location, monitoring results, answers to buyer questions, and your service work after installation.

Can a solar company post a customer's savings?

Yes, with the customer's permission and with the context: system size, location and period. If the result is better than typical, the post should state what customers generally achieve, and you should hold evidence for both figures.

Do referral posts need a disclosure?

Yes. A customer who earns a referral reward has a material connection with you, and under the FTC's Endorsement Guides that connection should be disclosed clearly in the post.

Can solar ads mention the 30% federal tax credit?

Not as an offer to homeowners for new systems. The IRS says the Residential Clean Energy Credit is not available for property placed in service after 31 December 2025.

Which social platform is best for a solar installer?

Facebook for most residential installers, because homeowners in your area are there. Instagram and YouTube for install videos and explainers, and LinkedIn for commercial solar.

The quote request that starts with an assistant

A homeowner who has watched your install videos for months may still ask ChatGPT or Gemini before calling: "which solar installers near me have good reviews and do batteries?" The assistant answers from what it can read, such as review sites, your service and location pages, and local news. Social videos rarely reach that answer, which is why the facts in them belong on your website too. Checking whether the assistants name your company for those questions is a new kind of visibility check, and AI Knows Us is a service built for exactly that.
