Solar Lease vs Loan vs Cash Purchase: Which Is Right for Your Home?
Lease, loan or cash for rooftop solar? How ownership, escalators, dealer fees and home-sale rules differ, and how to pick the option that fits you.
Cash usually gives the lowest total cost and the most savings because you own the system outright. A loan also gives you ownership but can carry hidden dealer fees. A lease or power purchase agreement needs little money upfront, but you don't own the panels, payments may rise with an escalator, and a home sale gets more complicated.

A solar salesperson offers you 3 ways to go solar: pay cash, take out a loan, or lease the system for “no money down.” Each one is pitched as the smart move. They can’t all be the best deal for you.
How you pay for solar can matter as much as which panels you buy. It changes who owns the system, who gets any incentives, how much you pay over 20-plus years, and what happens when you sell your house.
This guide compares the 3 main routes (plus PPAs and PACE financing) so you can pick the one that fits your budget and plans.
The 4 main ways to pay for solar
- Cash purchase: You pay the full price upfront and own the system on day one.
- Loan: You borrow to buy the system and own it, paying the loan off over time. Solar-specific loans are usually arranged through the installer. You can also use a home equity loan or a loan from a bank or credit union.
- Lease: The solar company owns the system on your roof. You pay a monthly rent to use it and get the electricity it produces.
- Power purchase agreement (PPA): The company owns the system, and you pay a set price for each kWh it generates.
Leases and PPAs are called third-party ownership. According to a 2024 Consumer Financial Protection Bureau (CFPB) report, loans accounted for 58% of residential solar installs in 2023, cash for 19% and third-party ownership for 23%.
Solar lease vs loan vs cash at a glance
| Factor | Cash | Loan | Lease | PPA |
|---|---|---|---|---|
| Who owns the system | You | You | Solar company | Solar company |
| Upfront cost | Full price | Little to none | Little to none | Little to none |
| Total cost over time | Lowest | Higher (interest plus any dealer fee) | Ongoing payments for the term | Ongoing payments for the term |
| Monthly payment | None | Fixed loan payment | Fixed or rising rent | Varies with production; rate may rise |
| Who gets incentives | You | You | Company | Company |
| Maintenance and repairs | You (warranties help) | You (warranties help) | Usually the company | Usually the company |
| Typical term | None | Often 10 to 25 years | CFPB: typically 15 to 20 years | CFPB: typically 6 to 25 years |
| Home sale | System sells with house | Pay off or transfer loan | Buyer assumes or you buy out | Buyer assumes or you buy out |
| Best for | Owners with savings who plan to stay | Owners who want ownership without cash upfront | People who want low upfront cost and no maintenance | Same as lease, paying per kWh |
Key takeaway: Ownership is the big dividing line. Cash and loans make the system yours, along with its savings and risks. Leases and PPAs keep the company as owner, which lowers your upfront cost but usually your long-term savings too.
Paying cash: lowest cost, most savings
If you can afford it, cash usually delivers the best long-term value. Berkeley Lab’s 2026 data update found cash-purchased residential systems had a median installed price of about $3.00 per watt in 2025, compared with about $4.50 for loan-financed systems. Every dollar of bill savings goes to you, and there’s no interest.
The downsides: you tie up a large amount of money, you’re responsible for upkeep after warranties, and you take on the risk that the system underperforms or your utility changes its export rates. Since the 30% federal homeowner tax credit isn’t available for systems placed in service after December 31, 2025, according to the IRS, your payback relies on bill savings and any state or utility incentives. Our guide to whether solar is worth it shows how to run that math.
Solar loans: ownership without the upfront cost
A loan lets you own the system and keep the savings while spreading the cost out. If your monthly loan payment is lower than your bill savings, you come out ahead from the start.
Watch for 2 big catches:
Hidden dealer fees
The CFPB found that many solar-specific loans include “dealer fees” that typically run 10% to 30% of the cash price and can exceed 50%. These fees are often built into the loan amount rather than shown in the stated APR, so a low advertised rate can be misleading. Always ask for the cash price and compare it with the loan amount.
Tax-credit prepayment traps
Many solar loans were designed around the federal tax credit. The CFPB reported that payments often jump around the 19th month unless the borrower makes a large prepayment, often 30% of principal. With the homeowner credit gone for 2026 installs, make sure any loan you sign doesn’t assume a refund you won’t get.
Compare an installer’s loan with a home equity loan or personal loan from your own bank or credit union. Our guide to how online personal loans work explains how to compare APRs and fees, and how credit scores are calculated explains what lenders look at.
PACE financing
Some states allow Property Assessed Clean Energy (PACE) loans, which you repay through your property tax bill. The Federal Trade Commission (FTC) warns that PACE places a lien on your home and missed payments can lead to default and foreclosure. A CFPB rule effective March 1, 2026 applies mortgage protections, including ability-to-repay checks, to PACE loans.
Leases and PPAs: low upfront cost, less control
With a lease or PPA, the company designs, installs, owns and usually maintains the system. You get lower electricity bills (if the deal is fair) without a large upfront payment.
The FTC notes that leases can run about 20 years and ending one early may be difficult and expensive. Before you sign, check these terms:
Escalators
New York’s Attorney General defines a price escalator as scheduled increases in what you pay the solar company. The CFPB notes PPA rates may escalate 1% to 5% a year.
Escalators compound. In a hypothetical example, a $120 monthly lease with a 2.9% annual escalator would reach about $238 a month by year 25. Over 25 years, you’d pay about $51,800, versus $36,000 with no escalator. If utility rates rise more slowly than your escalator, your savings shrink or disappear.
Production guarantee
Ask for a written guarantee of how much power the system will produce and how the company compensates you if it falls short. New York’s Attorney General recommends getting one in any lease or PPA.
Who gets the incentives
Because the company owns the system, it claims tax credits and usually keeps renewable energy certificates, the FTC notes. Under IRS rules, business-owned wind and solar facilities that begin construction after July 4, 2026 must be placed in service by the end of 2027 to qualify for the business credit, so lease and PPA pricing may shift. Ask how much of any credit is reflected in your price.
End-of-term options
Find out what happens when the term ends: renewal, buyout at fair market value, or removal of the panels.
What happens when you sell your house
This is where financing choices bite. New York’s Attorney General warns that selling your home typically doesn’t relieve you of the obligation to make all remaining payments on a loan, lease or PPA.
- Cash: The system is part of the house. You can market it as a feature.
- Loan: You’ll usually pay off the loan at closing, or the buyer assumes it if the lender allows. The CFPB notes that liens tied to some solar loans can complicate title and may need to be released or subordinated before a sale or refinance.
- Lease or PPA: The buyer must agree to take over the contract, and the FTC notes they may need to meet the company’s credit requirements. If they won’t, you may have to buy out the contract. Moving panels to a new home is uncommon.
If you might move within a few years, ask for the transfer process and buyout price in writing before you sign. A good real estate agent can tell you how solar contracts affect sales in your market.
Where to start: how to choose
- Decide how long you’ll stay. Under 5 years leans toward no solar or a flexible option like community solar. 10-plus years favors ownership.
- Check your savings and credit. Cash beats financing if you can afford it without draining your emergency fund. A budgeting app helps you see what’s realistic.
- Get 3 quotes, each with a cash price. Compare price per watt. Our guide on solar panel cost explains how.
- Get an outside loan quote from a bank or credit union to compare with the installer’s loan.
- For leases and PPAs, compare total payments over the full term, including escalators, against your expected bill savings.
- Read the contract for escalators, production guarantees, transfer rules, buyout prices and roof-repair responsibilities. Make sure any verbal promise is in writing.
- Use your cancellation rights if you need them. The FTC’s Cooling-Off Rule generally gives you 3 business days to cancel a covered sale made at your home.
The bottom line
Cash is usually cheapest, loans give you ownership with less upfront money if you avoid inflated fees, and leases or PPAs trade long-term savings for convenience. The right choice depends on how long you’ll stay, how much cash you have, and how comfortable you are owning equipment on your roof. Whatever you pick, get the cash price, read every escalator and transfer clause, and never sign the same day. This is general information, not legal or financial advice.

Frequently asked questions
Is it better to lease or buy solar panels?
Buying is usually better if you can pay cash or get a fair loan and plan to stay 10 or more years, because you keep all the savings and the system adds to your home. Leasing suits people who want little upfront cost and no maintenance, but long-term savings are usually lower and escalators can erode them.
What is a solar escalator clause?
An escalator is a scheduled increase in your lease payment or PPA rate, usually a fixed percentage each year. The CFPB notes PPA rates may rise 1% to 5% annually. Because increases compound, a small escalator can add thousands of dollars over a 20- or 25-year term. Compare it with how fast you expect utility rates to rise.
Can you sell a house with leased solar panels?
Yes, but it adds steps. The buyer usually has to agree to take over the lease and may need to meet the solar company's credit requirements. If they won't, you may need to buy out the contract. New York's Attorney General notes that selling doesn't end your obligation to make the remaining payments, so plan ahead.
Are solar loans a good idea?
They can be, if the terms are fair. A loan lets you own the system and keep the savings without paying upfront. But the CFPB found many installer-arranged loans include dealer fees of 10% to 30% or more, often hidden from the APR. Always ask for the cash price and compare with a bank or credit union loan.
What happens at the end of a solar lease?
It depends on the contract. Common options include renewing the lease, buying the system at a set or fair market price, or having the company remove the panels. Removal may require roof repairs. Check the end-of-term terms before signing, and ask how much a buyout would likely cost if you decide to keep the system.
Does leasing solar affect my credit?
It can. Solar companies often check your credit before approving a lease or PPA, and some contracts or loans come with filings that show up in title searches. Missed payments can be reported and lead to collections. A lease generally doesn't count as a mortgage, but lenders may consider the monthly payment when you refinance or buy another home.
Do I get the tax credit if I lease solar panels?
No. The solar company owns the system, so it claims any available tax credits and often keeps renewable energy certificates. Separately, the federal homeowner credit isn't available for systems placed in service after December 31, 2025. A fair lease or PPA should reflect any credit the company receives in a lower price.
