Should you buy out your solar lease? How the price compares with what you still owe

What a buyout actually changes

Under a lease or PPA the solar company owns the equipment. The U.S. Department of Energy's Homeowner's Guide to Going Solar describes the arrangement in those terms: leases and PPAs let consumers host systems that are owned by solar companies, and because the consumer does not own the system, the guide says the consumer is not entitled to the tax benefits that go with ownership (DOE, checked October 2026). A buyout moves that ownership to you. It does not change the panels, the roof or the wires. It changes who owes what to whom from that day forward.

Three things stop and three things start. The monthly payment stops, along with the escalator that has been raising it each year. The company's role as owner of the panels stops, which also ends its role as the party that is usually expected to service them. The Federal Trade Commission's consumer page on home solar says that leasing companies will probably be responsible for system maintenance and tells shoppers to confirm who handles repairs and whether they must pay for them (FTC, Solar Power for Your Home, April 2022, checked October 2026). After a buyout the answer to that question becomes you.

What starts is a set of owner costs and owner risks: upkeep, an inverter that may need replacing, insurance on equipment you now own, and any shortfall in production that a lease guarantee used to cover. Each of those is a real cost with a real price, and none of them appears in the buyout quote. Pricing them is the second half of the decision, and it is the half a buyout quote leaves out.

How the buyout price gets set, and what to ask for

The FTC page tells lease and PPA shoppers to check, before signing, whether they can renew, buy the system or have it removed when the contract ends, and how much each option costs. It does not say how a buyout price is calculated, and neither does DOE's guide. We could not retrieve the Solar Energy Industries Association's residential consumer guide for this review (the server refused the request), so nothing on this page is attributed to it. That leaves your own contract as the only authoritative source for the formula.

A contract can fix the price in several ways. It can print a schedule of buyout amounts by year. It can name a formula, such as a stated share of the remaining payments. It can promise an appraised value determined at the time of the request. Or it can say nothing precise and leave the company to quote a price on request. Each has a different practical consequence: a printed schedule lets you plan years ahead, an appraisal makes the number unpredictable, and silence means you are negotiating. Read the purchase-option clause first and mark which of the four you have.

Then ask the company for the price in writing, with the date it is good through. A phone quote that is not tied to a date is not a number you can compare with anything. The written quote should cover five points.

• Price and expiry: the dollar amount, the date through which it holds, and whether it changes if closing slips by a month.
• Add-ons: taxes, transfer or administrative fees, and any charge for the final bill.
• Formula: whether the amount comes from a printed schedule, a formula in the contract, or an appraisal, with the section number.
• What is released: a bill of sale or similar transfer document, and written release of any recorded security filing on the panels.
• What survives: which equipment warranties and workmanship coverage remain in force after the transfer, and who services them.

The three numbers that decide it

Strip the decision down and a buyout is a trade. You give up a stream of future lease payments in exchange for paying one amount now, and you take on a stream of owner costs in return. The electricity is the same either way, so it drops out. That leaves three numbers to compare.

The first is the nominal remaining payments: add up every payment from the next one to the last, including each escalator step. The second is the present value of those payments, which discounts later payments because a dollar due in 2038 is worth less to you today than a dollar due this month. The discount rate is your choice and it is not a fact; it stands for what the cash could otherwise earn or save you, for example the interest rate on debt you would repay with it. This guide shows 3%, 6% and 8% so you can see the effect. The third is the cost of ownership you take over, discounted the same way.

The break-even buyout price is the present value of the payments you stop making, minus the present value of the owner costs you start paying. Quotes below that number favor buying out; quotes above it favor continuing to pay. Everything the quote does not capture, such as the value of a production guarantee you give up, pushes the true break-even down, so treat the number as a ceiling, not a target.

Worked example: a buyout quote after eight years

Every input is printed so you can swap in your own. This is an illustration, not a price you should expect to be quoted.

• Lease: 240 monthly payments, $145 a month in year 1, rising 2.9% each year on the anniversary. The twenty-year total is $46,282.
• Timing: eight years of payments made (96), 144 left. The next payment is $182.26 a month and the last is $249.61.
• System: 8 kW DC, with first-year production of 1,400 kWh per kW (11,200 kWh) as a planning factor, and 0.5% a year degradation. DOE's Federal Energy Management Program says PV module efficiency degrades at about 0.5% per year (DOE FEMP, checked October 2026).
• Owner upkeep: $34 per kW DC per year, the operations and maintenance figure in the DOE 2025 first-quarter residential benchmark, stated in 2024 dollars (DOE solar cost benchmarks, checked October 2026). On 8 kW it is $272 a year, held flat here.
• Inverter reserve: $2,000, set aside in ownership year 8. This is an illustration, not a price; real inverter costs vary, and the inverter replacement guide covers how to price one.

Add up the 144 remaining payments and you get $30,864. At a 6% discount rate they are worth $21,522 today. Over the same 12 years the owner costs have a present value of $2,280 for upkeep and $1,255 for the inverter reserve. The break-even buyout price is therefore $21,522 minus $2,280 minus $1,255, which is $17,987.

Now test four possible quotes. The 144 remaining payments divided by the 125,625 kWh the system should make in years 9 through 20 (after degradation) work out to 24.57 cents per kWh. For each buyout quote, the cost per kWh as owner is the price plus 12 years of upkeep ($3,264) plus the $2,000 inverter reserve, divided by the same 125,625 kWh. These totals are undiscounted, which is why they sit above the break-even logic in the table that follows.

Reading the four quotes

Each row below is a quote someone might hand you. The comparison is the amount you would still pay on the lease, $30,864, against the buyout price plus what ownership costs.

The undiscounted column makes the $22,000 quote look like a $3,600 saving, while the discounted view says it loses money. Both are true, and they answer different questions. The undiscounted total tells you what leaves your bank account over twelve years. The discounted version asks whether you would be better off keeping the $22,000 now and paying the lease slowly. If you would otherwise have to borrow at 8% to fund the buyout, use the 8% row, where the break-even drops to $16,144. If the money is sitting in an account paying little, the 3% row applies and the break-even rises to $21,343.

Notice also how little the electricity price mattered. At no point did the example ask what a kilowatt-hour costs from the utility, because the panels produce the same kilowatt-hours under either choice. The utility price matters to a different decision: whether the whole arrangement, leased or owned, beats going without solar. That question belongs to the break-even price guide and to the rate pages at EnergyBS, such as its look at electricity rate increases.

How timing moves the break-even

The same lease gives very different break-evens depending on when you ask. Early on, many payments remain and each is worth nearly its face value, so the present value is high, but so is the number of years of upkeep you inherit. Late in the term, few payments remain and the figure shrinks toward zero. The table keeps every input from the worked example and changes only the number of years paid.

Two features of the table are worth pointing at. First, the break-even falls more slowly than the calendar suggests in the early years, because the escalator makes later payments larger. Second, the break-even at year 18 is about $5,051 for a system that still has years of output left. A quote of several times that number in the last two years of a term is paying for something other than the remaining payments, and you should ask what.

That second point bites hardest at the end of the contract. The FTC page says that after a lease contract ends the company must remove the system and put the roof back in its original condition, and it lists renewing, buying or removal as the end-of-term choices to price before signing. If the contract is about to end anyway, a buyout is a purchase of a twenty-year-old system, not a financing decision, and its value should be judged against what a system of that age can still deliver. The next section does that.

The age of the system you would own

A buyout is cheaper per payment avoided when the system is young, and riskier when it is old. DOE's FEMP page says PV systems have 20 to 30 year lifespans and notes that failure rates rise in later years as equipment ages. It also says most downtime and maintenance is tied to inverters, which are generally replaced whole when they fail (DOE FEMP, checked October 2026). Our guide to how long panels last goes through what that means for output and warranties, and the inverter guide covers the one expensive event most owners meet.

Degradation is slow but compounding. At 0.5% a year, the example system produces about 96.6% of its first-year output in year 8 and about 90.9% in year 20 (the factor is 0.995 raised to the number of years elapsed). That is why the buyout cost per kWh above uses 125,625 kWh for years 9 through 20 instead of twelve times 11,200. If your buyout is at year 18 and you plan to run the system to year 25, the final five years at the same degradation produce about 50,154 kWh, and you would carry the inverter risk for that whole stretch.

There is also a sequencing question. A buyout at year 8 buys a system with perhaps 12 to 17 productive years left, a roof that has to last as long as the panels, and an inverter that may still be on its first life. A buyout at year 19 buys a system near the end of the warranties you will read about below. The first case is a financing trade; the second is a bet on an old machine. Put them side by side before deciding which one you are being quoted for.

Warranty, monitoring and utility status after you own it

Ownership transfer does not automatically carry every protection with it, and a buyout quote rarely lists what carries over. Ask for four things in writing before you pay.

1. Equipment warranties. Panel and inverter warranties can run to the system's owner, so check who that is. Ask whether the manufacturer warranties are assigned to you at the buyout, what their remaining terms are, and whether the transfer needs a notice to the manufacturer. If the company holds them and will not assign them, the buyout loses part of its value.
2. Workmanship and roof penetration coverage. A leasing company that serviced everything may have promised to fix roof leaks at its own cost for the term. Ask whether that promise ends at the buyout or continues for a stated period. The FTC page notes that bids differ on what happens if you need to repair the roof after installation, so this is a known weak spot.
3. Monitoring and data. The monitoring account may be tied to the company. Ask for the transfer of the account to you, or for a way to see production independently, because you can no longer judge the system without it.
4. Production guarantee. If the lease promised a minimum output and credited the shortfall, the buyout ends that. Weigh it by looking at the monitoring history: if the system has met its estimate every year, the guarantee has cost the company nothing so far and is worth little to you now.

The utility side deserves its own question. Your export credit or net metering enrollment is tied to the utility account and the interconnection agreement, and we found no general rule saying that a change of system owner leaves the export rate unchanged. Some interconnection paperwork names the system owner. Ask the utility, not the solar company, whether the buyout needs a new or amended interconnection document and whether your export compensation, any locked-in rate, or any grandfathering would be affected. The mechanics of those rules are covered in net metering explained and, for California, in the net billing tariff guide. If your rate was set for a specific customer and system, a utility's answer on this point can be worth more than the buyout discount.

Liens, filings and the lender angle

Many leasing companies record a financing statement on the panels in the county land records, and a buyout should end with that filing released. Ask for the release as part of the payoff and get proof it was filed; the leased-solar sale guide sets out the fixture-filing rules and the termination-statement deadline under the Uniform Commercial Code, which states enact in their own versions.

The lender angle matters when you plan to refinance or sell after the buyout. A leased or PPA system is treated very differently from an owned one in the buyer's underwriting, and the sale guide walks through Fannie Mae's Selling Guide section B2-3-04 (version dated October 8, 2025). In short, a buyout can change how the next lender sees the house, because the monthly payment disappears from the debt calculation. It is one reason a buyout at sale is sometimes the right step even when it does not win on the pure arithmetic.

Whether it does win depends on what your buyer's lender will accept. The sale guide linked above sets out the choices at closing: transfer, buyout, prepayment and removal. If you are weighing a buyout only because you plan to sell, that guide and the moving and selling worksheet are the better starting points, because they ask what the buyer pays for the system, not just what you owe.

The other choices on the table

A buyout is not the only way out of a bad lease, and it is not always better than doing nothing. Four alternatives deserve a price before you commit.

• Keep paying to the end of the term. This is the default. Its cost is the remaining payments; its risk is the escalator and, at the end, the renew, buy or remove decision the FTC lists. Stay if the break-even sits below every quote you can get.
• Transfer to a buyer at sale. If you will sell within a few years, a transfer to a qualified buyer ends your obligation with no cash from you, subject to the company's approval and the buyer's lender. It is the path the sale guide covers.
• Prepay the remaining lease. This is an agreement to pay the rest early, the discount, if any, is in your contract; ownership does not pass. Ask what discount rate the company applies, then compare it with your own discount rate.
• Replace the system. A buyout of an old system competes with a new one. The site's comparison line, the U.S. Department of Energy's Q1 2025 residential benchmark of $2.95 per watt DC (modeled market price for an 8 kW system, 2024 dollars, checked October 30, 2026), puts an 8 kW system at $23,600. That is a comparison line, not a quote, and it does not include removal of the old panels. A buyout quote that approaches it for an aged system deserves a hard look.
