A solar lease is a 20-year legal contract on your home. The marketing pitch is simple — $0 down, locked-in electricity savings, no maintenance headaches. What's harder to find in the brochure is the escalator clause that raises your payment 60% over 20 years, the clause that complicates your home sale, and the insurance language that may leave a gap in your coverage. It's not that leases are bad deals — sometimes they genuinely make sense — but you need to understand what you're signing.
Here's what the fine print actually says, in plain English.
Disclaimer: Solar lease terms vary by company and state. This guide describes common structures — your specific agreement may differ. Review your full contract with a lawyer if needed before signing. Section 25D residential solar credits expired December 31, 2025. Section 48E applies to commercial/third-party owners like solar lease companies, not to you as the homeowner. Always get 3+ installer quotes before deciding.
Key Takeaways
- Typical leases start at $80–$150/month and escalate 2.9%/year — year 20 payment may be 60% higher than year 1
- Selling your home requires transferring the lease to the buyer or paying a buyout — this can complicate or kill a sale
- Section 48E (commercial solar credit) is claimed by the installer, not you — your savings come through a lower monthly payment, not a tax credit
- Homeowner's insurance may not cover leased panels — check your policy before signing
- End of lease: your options are typically purchase at residual value, renew, or have panels removed
The Escalator Clause: What It Actually Costs Over Time
Most solar leases include an annual payment escalator, typically 2.9% per year. That sounds modest, but compounded over 20 years it adds up significantly. A $100/month year-1 payment becomes roughly $160/month in year 20 — a 60% increase.
The escalator is designed to track projected utility rate increases. The logic: if your utility rate also rises ~3%/year, your net savings stay roughly constant. That's a reasonable assumption for long-term planning, but utility rates don't move in a straight line — they can stay flat for years, then spike, or (occasionally) drop. If rates stay flat while your lease escalator continues climbing, the economics erode.
| Year | Monthly Payment (2.9% escalator) | Annual Payment |
|---|---|---|
| Year 1 | $100 | $1,200 |
| Year 5 | $112 | $1,344 |
| Year 10 | $130 | $1,560 |
| Year 15 | $150 | $1,800 |
| Year 20 | $161 | $1,932 |
Total lease payments over 20 years on a $100/month starting payment with a 2.9% escalator: approximately $30,300. A $24,500 cash purchase (the 2026 national average for a 7 kW system) with no federal credit still costs less over 20 years, and you own the asset. The lease makes more sense when the cash or credit alternative isn't available, or when the lease terms are especially competitive.

The Home Sale Complication
This is the fine print issue that most surprises homeowners. When you sell your house, you have three options for the solar lease:
-
Transfer the lease to the buyer. The buyer assumes your remaining lease payments. Most lease agreements allow this with the company's approval, which requires the buyer to meet a minimum credit threshold. If the buyer doesn't qualify, or doesn't want the lease, this option fails.
-
Buy out the lease. Pay the installer the net present value of the remaining lease payments, minus the residual value of the panels. This can run $10,000–$20,000+ depending on how many years remain. That's money you're paying to remove an obligation from your home before transfer.
-
Move the system to your new home. A few contracts allow this; most don't. Equipment designed for a specific roof geometry doesn't transfer cleanly.
Real estate agents increasingly know to look for solar leases in disclosure documents, and some buyers walk away from homes with active leases rather than deal with the transfer process. Whether this affects your sale price or timeline depends on your local market.
If you're planning to sell within 5–7 years, this complication deserves serious weight in your lease-vs-buy decision. Owned systems — even financed ones — transfer with the home's title and don't require buyer credit approval.
Who Gets Section 48E (It's Not You)
The federal solar investment tax credit for solar installed after 2025 falls under Section 48E — and it applies only to commercial installations and third-party-owned systems like solar leases and PPAs. That means when you sign a solar lease, the installer is claiming a federal tax credit on the system installed on your roof. You're not.
Your benefit from this arrangement comes through the lower monthly payment that results from the installer's reduced net cost. Lease companies typically say the Section 48E benefit is "passed through" to customers in the form of a lower rate. How much of that credit makes it to your monthly payment versus staying in the installer's margin is not disclosed in consumer contracts — and there's no regulatory requirement that it be.
What you won't see: a line item on your contract showing "30% federal credit: minus $X." What you will see is a lease rate that reflects (to some degree) the installer's after-credit cost structure. Whether that represents good value requires comparing it to owned-system economics, which the Solar Lease vs Buy Calculator can help model.
Insurance: Check Your Policy Before Signing
Homeowner's insurance policies cover structures and equipment attached to your home — but whether that coverage extends to equipment you don't own varies by policy and insurer. Some homeowner's policies explicitly exclude leased equipment. Others cover it under personal property riders. A few require a separate endorsement.
If your home suffers fire damage or a storm tears panels off your roof, you want clarity on who pays to restore the installation — you, your insurer, or the leasing company. The solar lease company carries its own insurance on the equipment, but coordinating claims between your insurer and theirs after an incident is messy.
Before signing a lease, call your homeowner's insurance agent and ask specifically: "If solar panels leased from [company name] are damaged or destroyed, what does my policy cover?" Get the answer in writing.
Maintenance: Who Handles What
One of the genuine advantages of a solar lease is that maintenance is the installer's responsibility. If panels underperform, inverters fail, or monitoring shows production gaps, the lease company is contractually obligated to address it. You're not paying out of pocket for inverter replacements that can run $1,500–$3,000.
In practice, the quality of this maintenance coverage varies by company. Ask specifically: what is the response time guarantee for production issues? What is defined as a "material" production shortfall that triggers a response? Does the agreement have a production guarantee, and if so, what's the remedy if they don't meet it?
End-of-Lease Options
When your 20-year lease term ends, you typically have three choices:
-
Purchase the system at residual (fair market) value. This is usually offered as the first option, and the price depends on what a 20-year-old solar system is worth at that time. Current guidance suggests that residual value may be low — panels degrade ~0.5% per year, so a 20-year-old 7 kW system may be producing at 90–93% of original capacity. Residual value pricing terms should be spelled out in your original contract; vague language is a risk.
-
Renew the lease. The installer offers a new lease term on the same equipment. Payment terms will reflect current market conditions — possibly better, possibly worse than your current rate.
-
System removal. The installer removes the panels. You're left with a roof that was penetrated for 20 years. Some contracts specify that the installer is responsible for patching those penetrations; others are silent on this. Confirm removal terms before signing.
Comparing Lease Terms Across Installers
| Term to Compare | What to Look For |
|---|---|
| Escalator rate | Lower is better; 0–2% is good, 2.9% is typical, 3.9%+ is high |
| Production guarantee | Specific kWh guarantee with defined remedy if missed |
| Buyout terms | Fixed schedule or formula for early termination/home sale |
| End-of-lease purchase option | Price fixed or formula-based; "fair market value" is vague |
| Transfer approval process | How quickly does the company process buyer credit checks? |
Bottom Line
A solar lease can make sense — especially when upfront cost is the constraint and the alternative is staying on full grid power for another decade. But it's a 20-year financial commitment on your home, and the terms deserve careful review. The escalator, the home sale clause, the insurance gap, and the Section 48E pass-through are all real considerations that don't show up in the headline "$0 down" pitch.
