Solar Lease Buyout: How Pricing Works and What Happens at the End of Your Term
In this article

Short answer: Yes, most solar leases and PPAs include an option to buy the system. When that option opens varies: some agreements give you a standing right from around year five, others tie it to selling the home. The price is almost always the system’s fair market value at the time you exercise, determined by a third-party appraisal. Find the section called "Purchase Option" in your agreement and you will know which applies to you.

This comes up constantly, so here is a clear walkthrough of how buyout pricing works, when you can use it, and what your choices are when the term ends.

Can I buy out my solar lease or PPA?

Almost always, during windows your contract defines.

Sunwise currently offers third-party ownership through Palmetto’s LightReach, EnFin and GoodLeap. Here is how each one handles the purchase option. Terms change, so treat this as the starting point for a conversation with your rep rather than the last word.

The EnFin difference is worth knowing before you sign. LightReach gives you a standing right to buy from year five onward for any reason. EnFin’s lease ties the mid-term option to a home sale: the purchase rights arise on the sale of the home, provided that sale is after the fifth anniversary of the commercial operation date; if EnFin ceases operations and fails to provide a substitute provider; and at the end of the initial term. If buying the system outright at some point matters to you, that belongs in the conversation up front.

The applicable agreement sets the purchase window. Tax-credit recapture is one reason providers commonly use a five-year threshold.

Why the option opens around year five

The federal investment tax credit on a solar system vests over five years under IRC Section 50(a). The Instructions for Form 4255 set the schedule: a transfer of ownership in year one claws back 100% of the credit, year two 80%, and so on down to zero once five full years have passed.

Transferring the system to you counts as a change in ownership. So providers write the purchase window to open once the credit has fully vested. Your lockout is not a sales tactic, it is the tax code translated into contract language, and it expires on a date you can calculate from your in-service date.

How solar lease buyout pricing is calculated

Fair market value by appraisal appears in the LightReach and EnFin examples discussed here. Confirm the purchase option in your own agreement, including GoodLeap terms, before planning a buyout.

Prepayment is a separate transaction. Buying the system and prepaying the agreement are two different things at two different prices. LightReach's lease prices prepayment as the remaining monthly payments "discounted by five percent (5%)," and the PPA points to a prepayment figure in Exhibit F. Ask for both numbers, because which one is lower depends on where you are in the term.

Buyout terms are not standardized. New York’s state energy authority puts it plainly: "methods of calculating buyout prices can vary," and while "some contracts provide for an option to buy out at the fair market value of the system," others do not (NYSERDA homeowner guide).

The variation you are most likely to meet elsewhere is a greater of clause, where the price is whichever is higher between fair market value and a stated minimum. That puts a floor under the number. SEIA’s model power purchase agreement uses exactly that construction, setting the price at "the greater of the Fair Market Value of the System or the Termination Payment," with an independent appraiser brought in if the parties cannot agree on value (SEIA model PPA). That model is written for commercial projects, but the drafting pattern shows up in residential paper too. Some agreements run the other way and cap the price at the lower of an estimate and the appraisal.

Neither variation appears in the LightReach or EnFin paper. Both are worth checking for in any agreement you are handed.

What does a buyout cost at year 5 versus year 10?

Ask your provider for a dated purchase quote and, separately, a prepayment quote. The purchase price depends on the valuation method and purchase window in your agreement. Prepayment settles future payments while ownership and service can remain with the provider.

A clause that says payments are discounted by 5% does not, by itself, establish a 5% annual discount rate. Use the contract’s calculation and completed payment exhibit. Your provider can explain how the figure changes with the remaining term.

The useful comparison includes the purchase price, remaining payments, expected production and the service responsibilities you would take on as the owner.

Does the tax credit the provider received come off my buyout price?

The provider’s previously claimed tax credit is not automatically deducted from your purchase quote. A lease or PPA can use owner-side tax benefits to support its pricing, while a later purchase follows the valuation method in the agreement.

For a fair-market-value purchase, the question is what the system is worth at the time of sale. Compare the written buyout quote with your remaining payments and expected energy costs. Savings depend on the agreement, production, utility rates and any annual payment increases.

If you are comparing this against owning a system outright, our guides to what solar costs and 2026 financing options lay out the current numbers, and our overview of leases and PPAs explains how the credit flows through to pricing.

How does the third-party appraisal actually work?

This is where the number comes from, and it is worth understanding in detail because most homeowners are told "fair market value" and left to guess what that means.

What the appraiser is being asked

An appraisal can use the income approach: the system is valued as an asset that produces something worth money, so the question is what the remaining electricity production is worth today.

Your contract says who runs it. LightReach's lease is specific: "LightReach will determine the FMV of the System by hiring an independent appraiser to estimate the value of a comparable in-service photovoltaic solar system in your state and utility service area."

EnFin hires the appraiser too, but adds something most agreements do not. You have "the right to obtain, at your own expense, a professional appraisal by an independent third party (agreed to by EnFin)." Two conditions attach: you pay for it, and EnFin has to agree to the appraiser. If the number you are given looks off, that clause is how you test it.

What goes into the valuation

LightReach lists the factors in the contract itself: "the System's age, location, conditions, size, and other market characteristics such as equipment type, service costs, and value of electricity in your area, and any applicable incentives."

One available valuation tool is PV Value, developed by Sandia National Laboratories with Solar Power Electric. Its user manual explains an income-based approach. Ask which model and assumptions your appraiser uses; values in an older manual are not necessarily the inputs for your system. Relevant inputs include:

  • Production modeling through NREL's PVWatts, using your ZIP code, system size, tilt, azimuth, array type and shading
  • Derate factor, 0.77 by default, adjustable with a commissioning report
  • Degradation, 0.5% per year for standard crystalline silicon panels, so a ten-year-old array is modeled at about 95% of its original rating
  • Your utility rate and an assumed escalation rate, which is why the same system appraises differently in PSE&G territory than in a lower-rate service area
  • Remaining useful life, generally set to the balance of the panel manufacturer's power production warranty
  • A discount rate, built from a benchmark mortgage rate plus a risk premium the manual puts at 50 to 200 basis points, averaging 125
  • Operations and maintenance cost per watt, subtracted from the income stream
  • Inverter replacement status, which matters on systems past about 15 years

An income model uses those inputs to estimate present value. The appraiser’s methodology and the agreement determine the final valuation.

Does the appraisal factor in the tax credits the provider received?

Short version: incentives count, but only the ones a buyer could still use.

The valuation standard is what a hypothetical buyer would pay. SEIA's guidance on valuing solar assets puts it directly: "the amount of investment tax credit and depreciation considered in the valuation must be based on the perspective of the buyer, applying the concepts that a hypothetical buyer would apply" (SEIA). Credits the provider already claimed are part of the provider's history, not a feature of the equipment, so they do not show up as a deduction.

What does move the number in Pennsylvania, New Jersey and Delaware is the incentives that travel with the system. Net metering arrangements and SREC eligibility are real, ongoing value to whoever owns the array, and they belong in an appraisal. If you are in New Jersey with SREC-II registration or in Pennsylvania generating AEPS credits, say so and make sure the appraiser accounted for it, because it cuts both ways: it supports the value, and it is value you receive after the purchase.

One timing note worth knowing. Some agreements state that for a purchase before the five year mark the fair market value "will include the recapture of any federal tax credits." That is an addition to the price, not a reduction, and it is another reason the purchase windows open when they do.

Practical steps

  • Ask for the purchase option notice. LightReach issues a purchase option notice each year of the term, including an estimated fair market value purchase price, with the first one delivered before the fifth anniversary. If your provider sends something similar, that is your starting number.
  • Check your exhibits. The LightReach PPA carries an estimated FMV in Exhibit F, and EnFin's Exhibit B holds your production and payment schedule. Those exhibits carry the dollar figures, and they are filled in on your executed copy.
  • Ask what inputs were used. Utility rate, escalation rate, discount rate, degradation rate and remaining useful life drive the whole calculation. A reasonable appraiser will tell you.
  • See whether you can order your own appraisal. EnFin's lease allows one at your expense, with an appraiser it agrees to. LightReach's does not provide for a competing appraisal, so the figure it produces is the figure.
  • Do not confuse it with a home appraisal. Leased panels are treated as personal property and Fannie Mae instructs appraisers not to include them in a home's appraised value. A buyout appraisal answers a different question and will produce a different number.

What happens at the end of a solar lease?

At the end of the initial term, usually 20 to 25 years, you choose from a short menu: renew, buy the system, or have it removed.

LightReach's lease allows renewal for up to ten additional years in two five-year periods, priced at the then current fair market value of the system. Its end-of-term purchase is also at fair market value, determined through the PV Value tool. EnFin's lease includes an end-of-term purchase option at fair market value as well.

That structure is the industry norm. NYSERDA and the Clean Energy States Alliance describe the same three paths in their homeowner guides: at the end of the term you can "renew the contract and continue the monthly payments," "purchase the system at a designated price or the fair market value of the system, which may or may not be negligible after the term of a contract," or "have the third-party lender arrange for system removal" (CESA homeowner guide). Renewal is commonly offered for up to ten more years, often in two five-year increments.

If you want the panels gone, that is on the provider. The CFPB states that "at the end of the lease, the lessor is responsible for uninstalling and removing the panels" (CFPB Issue Spotlight: Solar Financing).

One thing to plan for: ownership does not transfer automatically when the term ends. A 20-year-old system's fair market value is typically modest, but you do need to exercise the purchase option to own it. NYSERDA's homeowner guide walks through the same three choices.

What about warranties after a buyout?

Worth lining up before you close, because the service picture changes when ownership changes.

Equipment warranties may remain available after purchase, subject to their transfer conditions and remaining terms. Obtain confirmation of any registration or transfer steps. Also confirm which maintenance, monitoring, repair and production-guarantee obligations end under your agreement.

Compare parts and labor coverage before buying. Some equipment warranties include eligible labor, while others leave service costs to the owner. Ask for the equipment list, warranty documents and a service plan for the period after purchase. Our Solar Insure guide explains installation-time coverage and why a later buyout does not automatically qualify an existing system for a new warranty.

Getting your real buyout number

  1. Find your agreement and look for "Purchase Option," "Early Purchase Period," "Prepayment Price" or "Termination Value."
  2. Note which pricing method applies and when your window opens.
  3. If there is a discount rate in the contract, run the remaining payments yourself so you know roughly where the number lands.
  4. Request the official quote in writing and ask them to show the calculation.
  5. Get the equipment list and warranty status before you decide.
  6. After you close, confirm the provider terminates its UCC-1 filing on the system. For residential equipment they are required to, and keeping a copy of your payoff date makes that easy to enforce.

For a buyout, request the official quote and warranty-transfer details from your agreement provider. If you are comparing payment options for a new solar installation, get a Sunwise solar estimate for your home in Pennsylvania, New Jersey or Delaware.

Solar Lease and PPA Buyout FAQ

Can I buy out my solar lease early?

Yes, once your contract's purchase window opens, commonly at the five or six year mark. The timing reflects the federal tax credit on the system, which vests over five years under IRC Section 50(a), so providers set the window to open after it fully vests.

How much does it cost to buy out a solar lease?

The purchase price follows your agreement’s pricing method, such as fair market value or a stated schedule. Request the current purchase quote in writing. A prepayment quote is a separate figure and does not necessarily transfer ownership.

Does the tax credit the solar company received reduce my buyout price?

There is no automatic deduction of the provider’s historical tax credit from a buyout price. The agreement’s purchase method controls the quote. Tax benefits can support lease or PPA pricing, but neither a credit nor a buyout guarantees savings for every household.

How is fair market value determined on a solar lease buyout?

By a third-party appraisal using the income approach, which values the system by the present value of the electricity it will still produce. Appraisers commonly use PV Value, a Sandia National Laboratories tool that models production through NREL's PVWatts and applies your system's age, size, tilt, shading, degradation rate, local utility rate, remaining warranty term and a discount rate. Most contracts have the provider hire the appraiser, though some call for a mutually acceptable one or let you commission your own.

Who pays for the solar buyout appraisal?

It depends on the agreement, and many are silent on it. LightReach hires the appraiser and its contract does not assign the cost to you. EnFin hires its own appraiser, and if you want a second opinion you pay for that one yourself and EnFin has to agree to who performs it. Check your purchase option section, and ask in writing if it is not stated.

Do SRECs and net metering affect the appraised value?

Yes, because they are incentives that continue with the system and benefit whoever owns it. In New Jersey and Pennsylvania in particular, SREC eligibility and your net metering arrangement are legitimate inputs to the valuation, and they are also value you receive once you own the array.

What happens at the end of a solar lease or PPA?

You can typically renew for a defined period, purchase the system at its then fair market value, or have the provider remove it at their expense. Some agreements also offer an upgrade to a new system. Ownership does not transfer automatically, so you need to exercise the purchase option if you want to keep it.

Who pays to remove the panels at the end of a lease?

The provider. The CFPB states that at the end of the lease, the lessor is responsible for uninstalling and removing the panels. Check your own agreement for any conditions attached.

What warranties do I get after buying out my solar lease?

Equipment warranties may continue for their remaining terms if transfer requirements are met. Confirm which provider services end and arrange any registration or service coverage required after purchase.

Can I sell my house with a leased solar system?

Yes. The buyer typically qualifies for and assumes the agreement, or the seller exercises the buyout at closing. Talk to your provider early, because the transfer process takes time and is easier to start before you list. The provider's UCC-1 filing will appear on the title search, which is normal and does not block the sale.
