Solar marketing after incentive changes: what to do now

Quick answer
Solar marketing after the residential tax credit ended means fewer buyers, longer sales cycles and more price questions. Update the pages that still sell the old incentive, and build content around leases, prepaid agreements, storage and your state’s utility rates. Judge results by qualified calls, and don’t compare 2026 with a deadline-inflated late 2025.
One short sentence changed solar copy. The IRS says the residential credit “will not be allowed for any expenditures made after December 31, 2025.” Any page that still tells a new homeowner they’ll get 30 percent back is now wrong, and that’s the first thing to fix.
Key takeaway Fix every page that still sells the ended credit before you build anything new. An out-of-date incentive claim costs trust.
What changed for US solar demand?
The federal residential credit ended for systems finished after 31 December 2025, and the market numbers now show it. Commercial and third-party-owned projects run under different rules, and California export pay changed earlier, so what hits you depends on whom you sell to.
What do the IRS, SEIA and CPUC say?
For customer-owned residential systems, the IRS says the credit equals 30 percent of qualified costs. The table sums up the documented rules by group.
| Who or what | Documented rule | Source |
|---|---|---|
| Customer-owned residential | The credit equals 30 percent of qualified costs. It ends for property placed in service after 31 December 2025 | IRS Residential Clean Energy Credit page |
| When an expenditure counts | When installation is completed. Paying before year end doesn’t preserve it | IRS FAQs (FS-2025-05, 21 August 2025) |
| Unused credit | Can be carried forward to reduce tax in future years | The same IRS page |
| Commercial and third-party-owned (Sections 48E and 45Y) | Projects qualify if construction began by 4 July 2026, or if they’re placed in service by 31 December 2027. No ban on third-party leased systems. Foreign-entity restrictions start in 2026 | SEIA’s July 2025 summary (SEIA, 21 Jul 2025) |
| California | New interconnection customers of the large utilities have been on the net billing tariff since 15 April 2023. Exported power is credited at a rate reflecting grid value, usually below the retail rate | CPUC, accessed 22 Oct 2026 |
The unused-credit rule matters for copy aimed at people who installed in 2025. The credit isn’t “gone” for them in every sense, but how much they can use is a tax question for their adviser.
Watch out The 4 July 2026 construction deadline has now passed, and tax rules are still being interpreted. Treat the above as the documented position on the dates shown, and send customers to a tax professional for their own case.
What does the market data show so far?
Residential installs are falling, and the industry’s own report says the bottom isn’t in. The Q3 2026 Solar Market Insight from Wood Mackenzie and SEIA covers Q2 2026 data. The table shows its main figures.
| Measure | What the report says |
|---|---|
| Residential capacity, Q2 2026 | 995 MWdc, down 12% from Q2 2025 and down 10% from Q1 2026 |
| Expected change in 2026 | A 23% contraction (previously 21%) |
| Expected growth, 2027 to 2031 | Average growth of 6% a year |
| Residential price | $3.36 per Wdc, down 1.4% year over year |
| Q2 leaders | California and Illinois, helped by high third-party ownership |
Q1 2026 held up because demand was pulled forward ahead of the deadline, the report says. Q2 then showed contraction in customer-owned installations. Installers reported longer sales cycles and falling close rates, and some had trouble moving from cash and loan sales to third-party-owned deals.
What does that mean for one buyer?
Here’s what that means for one buyer, as a hypothetical. An 8 kW system at $3.36 per watt costs $26,880 (8,000 watts times $3.36).
The old 30 percent credit would have been $8,064, leaving $18,816. Without it, the homeowner faces the full $26,880 unless they finance or lease.
Example In this hypothetical, a homeowner who would have paid $18,816 after the old credit now faces the full $26,880 unless they finance or lease.
The price is a national benchmark, not a quote, and your county may look nothing like it. Your sales team already feels that gap on every first call, and the pages should answer it before the call happens.
How does this change what homeowners search for?
Our expectation is that searches move away from “federal solar tax credit” and toward price, financing structure and backup power. That’s a theory, not a measurement, so test it against your own Search Console data before you build around it.
When a rebate is the reason to act now, the query is about the rebate. Once it’s gone, buyers still in the market ask three things:
- What does the system cost without it?
- Is leasing smarter?
- Does a battery make it worth doing?
What does industry press say?
Industry press points the same way. A December 2025 pv magazine roundup describes a shift toward prepaid third-party-owned deals.
In these deals the provider owns the system for “between five and 10 years” before it transfers to the homeowner. The roundup also expects more storage (pv magazine, 17 Dec 2025). Those are expert predictions, not search data.
How can you read your own queries?
You can read your own queries. In Search Console, the Performance report shows clicks, impressions, click-through rate and average position, and lets you filter the data (Google Search Console Help). Set the date range to 16 months and sort queries by impressions.
Then sort the top few hundred queries into three buckets: naming incentives, naming cost, and naming batteries or leases. Compare the last three months with the same three months a year earlier.
A hypothetical result shows how to read it. The table shows impressions by bucket.
| Query bucket | A year earlier | Now | Change |
|---|---|---|---|
| Incentive | 4,200 | 2,900 | Down 31 percent |
| Cost | 1,100 | 1,900 | Up 73 percent |
| Battery and lease | 600 | 1,400 | Up 133 percent |
Our view If incentive queries are shrinking and the other two buckets are growing, build cost and structure pages first. If all three are flat, don’t rebuild; fix the dead claims and wait a quarter. Small bases swing wildly, so ignore any bucket under a few hundred impressions.
Which pages should you fix first?
Fix the pages that make a claim the world no longer supports, then the pages that answer the new questions. Accuracy comes before expansion: an out-of-date incentive claim costs trust and can create legal exposure, while a missing page only costs reach.
This is the order we’d use on an installer site. Budget a few days of focused work, which is our estimate for a typical site and not a measured figure.
- Search your own site for “tax credit”, “30%”, “incentive”, “rebate” and “federal”. The quick version is a site: search in Google for each term, and the better version is a crawl export with a text search. Collect every URL, including blog posts, financing pages and city pages.
- Sort each hit into three buckets: still true, true only in some cases, or no longer true. A line saying homeowners “can claim 30% back” on a new customer-owned system lands in the third.
- Rewrite the third bucket first. Say what ended and when, then describe what’s available now. If you’re not sure, say less and send the reader to a tax professional.
- Hit the pages that carry the money next: your top service pages, the financing page and the home page. That’s where calls start.
- Add pages for the new questions:
- Lease and prepaid explainers
- “solar cost without the tax credit” for your state
- Storage and backup power
- A page on your utility’s export rules, if they affect payback
- Link the new pages from older pages that already earn impressions. Our view is that this helps a new page more than a footer link does.
- Record a baseline before you publish: clicks, impressions, and organic calls for the month before the changes.
Step 3 comes before everything else, because a site that still advertises an ended credit carries more risk than a site with thin content.
- Search your siteFind every mention of the credit, 30%, incentive, rebate and federal.
- Sort each hitStill true, true only in some cases, or no longer true.
- Rewrite the third bucketSay what ended and when, then what is available now.
- Fix the money pagesTop service pages, the financing page and the home page.
- Add pages for new questionsLeases, prepaid, cost without the credit, storage.
- Link the new pagesLink them from older pages that already earn impressions.
- Record a baselineClicks, impressions and organic calls before you publish.
One common mistake is rewriting the blog post and leaving the same claim in an image, a PDF brochure or an FAQ accordion. Search your downloads and your FAQ schema too. If a page’s structured FAQ still says the credit applies, the old answer can outlive the visible text.

Which message fits which kind of solar company?
The right content depends on what you sell and how you finance it. A cash-and-loan installer, a lease-heavy installer and a commercial developer face different problems, so one plan won’t fit all three.
This table is our view, a starting set of decision rules and not a promise about outcomes.
| If most of your sales are… | Fix first | Build next |
|---|---|---|
| Customer-owned residential (cash or loan) | Every page that still sells the ended credit | Cost-without-credit pages, payback honesty, financing explainers, storage add-on pages |
| Leases, PPAs or prepaid agreements | Contract-terms clarity: ownership, term, transfer, payments | A page per structure, comparison with buying, state-specific pages where you operate |
| Storage and backup power | Pages tying batteries to outages and utility rates | Backup-power explainers, battery-with-solar and battery-alone pages |
| Commercial projects | Pages that name the tax-credit deadlines you rely on | Pages by facility type, owner-versus-lease explainers, project-process pages |
Two rules sit under the table. If a structure isn’t available in your state, don’t write a page that suggests it is. And if you sell only one structure, say so plainly, because a reader who finds out late that you don’t offer leases may not return.
How do you word incentive claims without creating risk?
Say what the incentive is, who qualifies, and when. Avoid “free,” and avoid implied savings that depend on a credit the buyer may not get.
The FTC says solar claims must be truthful and comply with the FTC Act. It calls offers of “free” or “no cost” solar panels scams.
Watch out Avoid “free.” Avoid implied savings that depend on a credit the buyer may not get.
The FTC’s business blog also advises companies on three points (FTC Business Blog, 7 Aug 2024, last modified 20 Mar 2025):
- Disclose total costs.
- Be clear about financing.
- Do not overpromise savings from tax credits, rebates or incentives.
In practice the difference looks like the pair below, which is hypothetical copy for a customer-owned residential sale.
- Weaker: “Go solar and get 30% back from the federal government.”
- Safer: “The federal residential credit for customer-owned systems ended for systems finished after 31 December 2025. Other incentives may apply in your state or for leased systems. Confirm your situation with a tax professional.”
The second version is longer and less exciting, and it stays accurate. For a lease page the claim changes. Don’t borrow the buyer’s credit language at all, and describe the contract terms and what the homeowner pays instead.
This is general marketing guidance, not legal advice. Have counsel review claim language, especially anything about savings, financing and tax treatment.
Where do Google Maps and local search fit in?
Most installers serve customers at their homes, so the map listing is a service-area profile. Google ranks local results mainly on relevance, distance and prominence.
You can’t pay for a better local ranking. The lever you control is a complete, accurate profile with real reviews.
Google’s wording is that local results are “mainly based on relevance, distance, and popularity,” and that “there’s no way to request or pay for a better local ranking on Google” (Google Business Profile Help).
What helps in a shrinking market?
For a shrinking market, the practical point is that homeowners still shopping are comparing installers more carefully. In our view, reviews that mention the quote process, the install crew and the follow-up after activation help more now. They beat a generic “great service” line.
Check that your service areas match where you actually install. Our posts on how service areas work in Google Business Profile and rankings dropping after adding service areas cover the mistakes we see most often. A Google Business Profile optimization service fits only if you want help doing that work.
What does a longer sales cycle do to lead math?
A falling close rate means you need more leads for the same number of signed jobs, and every lead you buy costs more per job. Owned traffic, which keeps working after you stop paying, looks relatively better as that math worsens.
The numbers below are hypothetical and show only the arithmetic. Say an installer wants 10 signed jobs a month. At a 10% close rate that takes 100 qualified leads (10 divided by 0.10).
If the close rate falls to 8%, the same 10 jobs take 125 leads (10 divided by 0.08), which is 25% more. At a made-up $60 per lead, cost per signed job rises from $600 (100 leads, $6,000, 10 jobs) to $750 (125 leads, $7,500, 10 jobs).
Source: Hypothetical example
View the data as a table
| Item | Value |
|---|---|
| 10% close rate | $600 |
| 8% close rate | $750 |
That’s why we tell installers to track cost per signed job, not cost per lead. A steady lead price can hide a worsening business. Our post on lead value math for home-service companies walks through the method.
The solar leads versus SEO comparison covers how each channel charges and what you own afterward.
SEO isn’t a replacement for those channels in the first quarter. It’s a slower asset, and the SEO payback period post explains how to read that curve honestly.
How should you handle seasonality and the deadline distortion?
Don’t compare 2026 months with the same months of 2025 without adjusting for the deadline. Late 2025 and early 2026 were lifted by buyers racing to finish installs. Compare against a period you know was normal.
The Q3 2026 report says Q1 2026 held up because demand was pulled forward. It describes Q1 2026 as one of the strongest quarters in two years, apart from Q4 2025. A year-over-year chart that includes those months makes the current drop look worse than your underlying market is.
We don’t have a sourced seasonal curve for US solar, so we won’t invent one. Our method:
- Read at least two full years of Search Console data.
- Mark Q4 2025 and Q1 2026 as distorted, and say so in the report.
- If you only have one year, say that too.
Is there evidence from a solar site we worked on?
One of our case studies is a solar installer in India. It’s a fair example of the method. But it comes from a different incentive and regulatory system, so it doesn’t predict what happens to a US installer.
The figures are from Google Search Console.
| Search Console metric | April 2026 | September 2026 |
|---|---|---|
| Google clicks | 1,799 | 24,216 |
| Impressions | 188,515 | 2.19 million |
Average position was 5.8 in September 2026. The full write-up is on the solar case study.
Watch out The numbers don’t show lead counts, revenue, or how much came from any one change. Those weren’t disclosed.
We also have no US residential solar SEO results to show. Our US solar work so far is website builds, such as a US solar company in South Carolina, where we make no performance claim.
What does the data not show?
Several questions can’t be answered yet, by us or by anyone else writing on this topic.
- The floor. The Q3 2026 report says the data has yet to hit the trough for customer-owned systems, so we don’t know where demand settles.
- Your market. National numbers hide state and utility differences. California and Illinois behave differently from states with low retail rates.
- Search demand. We haven’t published, and won’t invent, search volumes. Whether queries shift as we expect is something your Search Console will show.
- Rule changes. Check current status before you write about it.
- The Q3 2026 report says Treasury’s February 2026 interim guidance (Notice 2026-15) left prohibited foreign entity definitions unresolved.
- More safe-harbor tables are due by 31 December 2026.
- Causation. Even when leads improve after a content change, a rising or falling market can mask the effect. Keep a baseline and a change log.
What should you do this month?
Run the audit, rewrite the dead claims, publish one page that answers a real buyer question, and set a baseline. That’s a few weeks of work, far smaller than a campaign. Check calls and signed jobs at about 90 days, our usual checkpoint, and ignore rankings alone.
Quick check Does any page on your site still tell a new customer-owned buyer they will get 30 percent back? If it does, fix that page first.

Frequently asked questions
Is solar still worth marketing after the federal tax credit ended?
Yes, but the sale changed. The Section 25D residential credit isn’t available for property placed in service after 31 December 2025, so customer-owned systems cost more out of pocket.
Leases, prepaid agreements and storage still find buyers. Your marketing has to explain those routes plainly and meet price questions earlier in the conversation.
Should I stop mentioning tax credits on my website?
No, but audit every mention. Cut any line that implies 25D still applies to a new customer-owned system.
Where another incentive applies, name it, say who qualifies, and point readers to a tax professional. Homeowners who installed by the deadline may also have questions about carrying unused credit forward.
Does SEO still make sense when demand is shrinking?
It can. In a smaller market each paid click and bought lead costs more per signed job, while pages you own keep working after you stop paying.
The catch is speed, because new pages take time to earn visibility. Judge it on qualified calls and booked consults, not on a ranking screenshot.
Which solar keywords should I target now?
Start from your own Search Console query report, then add price without incentives, lease or prepaid, battery backup and utility-rate questions for your state. We don’t publish search volumes here and won’t invent them. Cross-check your list against the questions your sales team hears on first calls.
How do I market solar leases and prepaid agreements?
Explain the contract in plain terms: who owns the system, for how long, what happens at transfer, and what the homeowner pays and when. The FTC advises companies to disclose total costs and be clear about financing. So put those details on the page and not only in the sales call.
How long until solar SEO changes show up in leads?
Nobody can promise a date, and Google publishes none. Our checkpoint is 90 days: read impressions and clicks in Search Console, then qualified calls.
A new site takes longer. Agree a baseline and a measurement plan before you start, and judge the work against those.
Can I still advertise a tax credit to homeowners who installed in 2025?
Only with care. The IRS says unused residential credit can be carried forward to reduce tax in future years.
But your copy shouldn’t promise a dollar amount or imply new buyers qualify. Describe the rule in general terms, give the date it applied to, and tell readers to confirm with a tax professional.
