Free Solar Salespeople Got Louder After the Federal Tax Credit Died. Here's the Loophole They're Using.

The loophole: one tax credit died, the other one didn't

Here is the situation in plain English. Two different federal tax credits used to subsidize residential solar. They lived in different sections of the tax code, and only one of them got killed.

Section 25D was the Residential Clean Energy Credit. If you, the homeowner, paid for and owned your solar system, you got 30% back as a federal tax credit. The One Big Beautiful Bill Act terminated this for any system placed in service after December 31, 2025. That part has been all over the news.

The part that has not been all over the news: Section 48E, the commercial Investment Tax Credit, is still in place for solar during a phase-down schedule. The kicker is that a residential solar lease or PPA is, legally, a commercial transaction. You are the host. The leasing company is the owner. The panels on your roof are their business asset. They claim the commercial credit. You claim nothing.

So in 2026, if you buy solar yourself, the federal government helps you with zero dollars. If you let a national leasing company put their panels on your roof and pay them every month for 25 years, the federal government still helps them. That is the gap that is funding the surge in door-knocking.

Why your doorbell is ringing in 2026

I have spent the last six weeks looking at door-to-door solar complaint volume across three state Attorney General consumer protection sites I can pull data from. The trend is not subtle. Filings about high-pressure solar sales jumped in the first quarter of 2026 compared to the same quarter in 2025 in every state I checked.

The reasons are straightforward.

Cash sales of residential solar fell off a cliff after the December 31 cutoff. SEIA's Q1 2026 market data showed residential installs down sharply year over year. National installers who had built sales teams around the 30% federal credit pivot suddenly had a sales force, a supply chain, and a business model that needed a new pitch. Leasing was the obvious move because the commercial credit is still there.

At the same time, utility rates kept climbing. In California and the Northeast, residential rates are now well above the national average and still going up. That makes any solar pitch sound better, including bad ones. A salesperson does not need to be honest about a 25-year escalator clause when the homeowner is staring at a utility bill that doubled in six years.

Mix those two things together and you get a lot of clipboards on a lot of porches.

A line-by-line walk through a real 2026 lease

My neighbor's contract was 47 pages. I am not going to reproduce the whole thing because it identifies the company and I have no interest in a defamation lawsuit. I will walk through the clauses by category, because every major leasing contract I have read in the last year follows roughly the same template.

The headline number on page 1

Page 1 of her contract says her monthly payment is $129. Her current average utility bill is $187. The salesperson did the math out loud and showed her she would save $58 a month.

That number is true on day one. It is not true on day two, in the sense that the contract starts adjusting it almost immediately. The starting payment is the part the sales pitch lives on. The escalator clause is the part it depends on.

The escalator clause (page 8 in her case)

Her contract has a 3.5% annual escalator. That means her $129 monthly payment becomes $133.51 next year, then $138.18, and so on. Over 25 years, compounded, that $129 grows to roughly $304. Her total payments add up to about $58,200 across the term.

The pitch for the escalator is that utility rates rise faster than 3.5% a year so you still come out ahead. Sometimes that is true. EIA national data shows residential rates rose roughly 5.7% annually on average over the last five years. But that is national. Look up your own state on the EIA site before you accept anyone's utility inflation assumption. In some states with regulated rates, the actual residential increase has been closer to 2% to 3% over the long run, which is below the escalator. In those states the gap closes and then flips.

The production guarantee (page 12)

Most national leases include a production guarantee. The company promises that the system will produce a certain number of kWh per year, and if it falls short, they cut you a check. Sounds great. Read the formula.

Her guarantee was for 9,200 kWh per year. The reimbursement formula was the shortfall in kWh, multiplied by a per-kWh rate that is significantly lower than her current utility rate. If the system underproduces by 1,000 kWh, she gets roughly $80 back. Her actual exposure on a year of weak production is closer to $130 to $160 in real utility costs she now has to cover from the grid.

The production guarantee is real. It is just smaller than the sales pitch makes it sound.

The buyout schedule (page 23, the one I am still angry about)

This is the page that should be on page 1. The contract has a table called Schedule B. It tells you what it costs to buy the system out and own the panels outright at each year of the lease. On her contract:

• End of year 5: $23,400 buyout
• End of year 10: $17,800 buyout
• End of year 15: $12,600 buyout
• End of year 20: $7,200 buyout
• End of year 25 (lease end): $1 buyout or remove

Notice the year-5 buyout: $23,400. A comparable system purchased outright in 2026 costs around $19,000 to $22,000 installed. So if she decides at year 5 that she would rather own it, she pays more to acquire a five-year-old roof full of used panels than she would have paid to buy new panels on day one. That is the gap I want everyone reading this to see clearly before signing.

The UCC-1 filing (page 31)

Buried at the back of most leases is a clause where you agree that the leasing company can file a UCC-1 fixture filing against your property. That is a public lien-like filing announcing that the panels on your roof belong to them, not to you, and that a future home buyer or lender has to deal with that.

UCC-1 filings show up in title searches. Mortgage lenders look at them. Title insurance underwriters look at them. Realtors I have talked to in the last year say a UCC-1 from a solar lease is now one of the most common reasons a home closing gets delayed by several weeks. Sometimes longer.

Lease vs buy: the math over 25 years

Let me put both options next to each other for a typical 7 kW system in a state with average utility rates. No state tax credit assumed. No federal credit (it is gone for owners). I am keeping these conservative on purpose.

The leased version is not catastrophic. It comes out roughly $5,000 to $10,000 behind the owned version over 25 years in the average case I just sketched. In states with weaker utility inflation than the 3% I assumed, the gap is wider.

The big things you give up with a lease are: the home value premium, the ability to sell the home without renegotiating someone else's contract, and roughly $5K to $10K of net lifetime value. What you avoid is the upfront $19,950 and the maintenance risk.

That is the actual trade. The pitch dresses it up. The trade is what it is.

What happens when you try to sell the house

This is the part most people do not think about until they are already nine months into a relocation.

With an owned system, the panels are part of the house. They transfer with the title. The buyer inherits the asset. The LBNL study I cite a lot found roughly a $15,000 home value premium for owned solar across 22,000+ home sales.

With a leased system, you have three options when you sell, and none of them are friction-free.

If you are reasonably certain you will be in the house for the full term of the lease, this matters less. If you might move in the next decade, factor in real friction, not hypothetical friction.

When a lease actually makes sense

I do not want this to read as a one-sided rant. Leases are a legitimate financial product. They are right for some households. Specifically:

• You don't have $19,000 to put down and HELOC rates in your area are above 9%.
• Your federal tax liability is small or zero, so even when the credit existed you couldn't fully use it. With it gone, the math changes less for you than for high earners.
• You are certain you will stay in the home for 20+ years.
• You live in a state with strong utility rate inflation (California, Massachusetts, Hawaii, Connecticut) where the escalator is more likely to stay below grid prices.
• You want zero maintenance responsibility and you have a known appetite for paying a premium to outsource hassle.

If three or more of those apply to you, a lease can be a reasonable call. Get two or three competing lease quotes anyway. Lease pricing varies more than people expect.

Eight red flags to flip to before you sign

If you do nothing else from this article, take the contract home and check these eight things before any pen touches any page. The salesperson saying “the offer expires today” is itself one of the eight.

The bottom line

My neighbor did not sign. She is buying instead, paying cash, and using South Carolina's 25% state credit to take $3,500 off the top. Her payback will land somewhere around year 10, and she will own a $19,000 asset that adds an estimated $15,000 to her resale value.

The leasing companies will keep knocking. The federal credit gap that gave them this opening lasts at least through 2027 under the current Section 48E phase-down schedule, possibly longer. The pitch will get more polished. The contracts will stay roughly the same length.

If a salesperson hands you a tablet to sign at the kitchen table, the right move is to ask for a paper copy of the contract, take it inside, and flip to the buyout schedule. That one page tells you everything you need to know about whether they are working with you or around you.
