Solar Lease: Contract Math Before You Sign | ChooseMyPower
A solar lease puts panels on your roof while the solar company keeps ownership. You make scheduled payments for a set number of years. A power purchase agreement, or PPA, uses the same third-party ownership model, but you pay for the electricity the system produces at a stated price per kWh. [1]
That sounds simple in a sales meeting. It is not simple on a real bill. Consumer guidance says a household with solar may still receive a utility bill, and a lease or PPA customer may also receive a separate bill from the solar provider. [1] A first-month payment is not the whole deal, and the salesperson sitting in your kitchen has no reason to walk you through year twelve.
At ChooseMyPower, the Real-Bill Ranking starts with the documents that determine what you owe: your actual electricity use, your retail plan, and your solar contract. Ranked by your bill, not our commission. The Real-Bill Ranking is not yet a live solar comparison tool. Until it is, this page gives you the paper version, the questions and the math you can run yourself before you use a first-year number to make a twenty-year decision.
What a solar lease is, and what you do not own
In a solar lease, the provider owns the system and rents it to you for a scheduled monthly payment. In a PPA, the provider owns the system and sells you the solar electricity it produces. A cash purchase or solar loan works differently, because the homeowner owns the system. [1]
That ownership line affects more than who handles the equipment. It determines the agreement you may need to transfer if you sell the home, the party that controls removal for roof work, and the contract language you must follow if the system underproduces. The CPUC says leases and PPAs commonly place monitoring, maintenance, and repairs with the provider, but the homeowner remains responsible for the contract. [1]
| Path | Who owns the panels? | What you pay | First receipt to read |
|---|---|---|---|
| Solar lease | Solar provider | Scheduled payment | Payment schedule, annual increase, transfer and buyout rules |
| Solar PPA | Solar provider | Price per kWh produced | Starting kWh price, escalator, production terms |
| Cash purchase or loan | Homeowner | Purchase or loan payment | Purchase price, financing terms, equipment and roof warranties |
The useful question is not whether one path sounds easier in the sales pitch. It is what this exact agreement requires from you at the start, in the middle, and when you need to exit.
The tradeoffs: when a lease gets considered, and what not owning costs you
A lease or PPA gets considered, honestly, in a narrow set of situations. You may not have the upfront cash for a purchase or loan down payment. You may not have enough tax liability to use a tax credit even if you owned the system. You may want the provider, not you, to be on the hook if a panel fails or output drops. In those situations, a lease trades a lower entry cost for someone else holding the asset.
The cost of that trade is real and it runs the other direction. You do not own the system, so you do not build equity in it the way an owner would. Your fixed monthly payment or per-kWh rate is a long-term obligation on your property, not a purchase you finish paying off into ownership. And because you do not own the system, a home sale becomes a negotiation with a third party’s contract terms, not a straightforward listing.
Neither side of that tradeoff is “better” in the abstract. It depends on your cash position, your tax situation, and how long you plan to stay in the house, which is exactly why the checklist below asks you to read your own contract instead of taking a sales pitch’s word for which side you land on.
A 7-point contract checklist before you sign
Competitors call this a “red flags” list. We call it what it is: a checklist of contract terms that determine your actual cost, built around the Teaser Test, ChooseMyPower’s name for the exercise of removing the headline payment from a sales presentation and checking whether the deal still holds up once the rest of the bill is added back in.
A solar lease is not a utility-bill replacement. It is a separate contract that must be checked against the electricity bill it is supposed to affect.
Before you sign, get each of these in writing and read it yourself. A verbal answer from a salesperson is not a contract term.
- The escalator clause. Find the exact language that raises your payment or your PPA price over time: the timing, the percentage or formula, and whether it applies to every remaining year of the term.
- The full payment schedule. Ask for the year-by-year number, not just the first-year figure. Write down the payment in the first year, a middle year, and the final year (or the kWh price, if it’s a PPA).
- The home-sale transfer clause. Can a buyer assume the agreement, and what happens if the provider does not approve them or the buyer does not want to take it on?
- The buyout or early-termination clause. Read the written method for calculating a buyout before you rely on any informal number a salesperson gives you.
- The maintenance and repair terms. “Free maintenance” is a pitch line until it is a clause. Look for a specific service commitment, such as a response time or a defined scope of what’s covered, rather than accepting the verbal promise.
- The end-of-term options. A lease or PPA runs for a set number of years and then the agreement has to say what happens next. Ask the provider to point you to the exact section covering renewal, purchasing the system, and removal, and don’t assume the answer until you’ve read it.
- The production guarantee. The contract should state how underproduction is measured and what remedy you get if the system falls short of the forecast.
This checklist does not promise you an outcome. It makes the tradeoffs visible before you sign instead of after.
Find the escalator clause and run the math yourself
An escalator is contract language that raises a lease payment or a PPA price over time. It’s one of the first places the Real-Bill Ranking looks, because a starting payment doesn’t tell you what the agreement requires later. The CPUC lists escalators among the disclosure items that can affect monthly payments. [1]
Don’t try to predict future utility rates to make this comparison. No seller, retailer, or homeowner knows exactly what your future electricity rate or future kWh use will be. Instead, request the payment schedule and write down the payment in the first year, a middle year, and the last year. For a PPA, do the same with the kWh price. Once you have those three numbers from your own contract, you can see the shape of the increase for yourself, without needing to trust anyone’s summary of it. Pair that with a full year of your own kWh history, not one hot or mild month, and you have the two inputs the checklist above is really asking for.
Check the lease against your actual utility bill
Solar doesn’t replace your electricity bill on its own, and the lease payment is a separate line item from whatever your retail plan still charges you. Before you compare a lease quote to what you pay today, you need to know what your retail plan actually bills for: the per-kWh energy charge, delivery charges from the utility that moves the power, any fixed base charge, and the conditions attached to any bill credit. Those charges don’t disappear because panels are on the roof. A production estimate from a solar salesperson is a forecast, not a guarantee, and it’s only as useful as the retail-bill assumptions built into it.
For customers in a deregulated part of ERCOT, this analysis has a specific tool. The Public Utility Commission of Texas says eligible ERCOT customers who are not served by a cooperative or municipally owned utility can choose a retail electric provider. [4] A solar lease is separate from that retail electricity plan, and that’s why the EFL Decoder, ChooseMyPower’s term for reading an Electricity Facts Label line by line, belongs in a solar-lease comparison for Texas shoppers. An EFL shows how a Texas retail plan is priced at stated usage levels, including the energy charge, TDU delivery charges, base charges, contract terms, and the conditions for bill credits. [5]
Read how Texas electricity rates are structured before you use a solar estimate as a bill forecast. Then read how to decode an EFL alongside the lease contract. If your retail plan offers a threshold credit, lower grid usage can move the bill into a different price pattern. Used 999 kWh? You may lose the bill credit. That’s bill math a solar quote may not show you, and it’s the same principle a homeowner in any state should apply to their own utility rate structure, even without an EFL to read.
For a system expected to export electricity, ask the retail provider how the current plan treats exported kWh, whether a credit is limited or expires, and whether the sales estimate assumes a specific plan. Keep the provider’s answer with the EFL. The EFL Decoder should test the retail-plan side of the proposal just as the checklist above tests the lease.
Read the home-sale and roof-work exit path before you need it
A solar lease should be reviewed like a long-term property agreement, because it is one. The National Association of REALTORS® says leased systems and PPAs involve third-party terms, payments, and restrictions that buyers and sellers need to understand. [2] The CPUC tells consumers to ask what happens if a buyer does not want or does not qualify to assume an agreement, whether early termination costs apply, and whether transfer fees apply. [1]
| Contract question | Why it matters in the Real-Bill Ranking |
|---|---|
| Can a buyer assume the agreement? | The provider may require the buyer’s approval or credit qualification. [1] |
| What happens if the buyer does not qualify? | The agreement should state the remaining options. [1] |
| How is a buyout calculated? | Read the written method before relying on an informal estimate. |
| Who handles removal for roof work? | Roof replacement can require coordination with the system owner. [2] |
| What does a production guarantee cover? | The contract should state the measurement and remedy. [1] |
The end of the lease term deserves the same treatment. A multi-year agreement has to say, somewhere in its text, what happens once the term is up: whether you can renew it, buy the system at a price set by the agreement, or have it removed. That section is easy to skip when you’re twenty years from needing it. Read it now anyway, because “now” is when you have the most leverage to ask questions before you sign.
Every provider may use different language. That’s why the Teaser Test ends with the actual agreement. Don’t assume a future buyer will accept the same terms just because the lease was acceptable to you today.
Keep tax-credit language on the right side of the contract
The IRS says the individual Residential Clean Energy Credit is not available for property placed in service after December 31, 2025. [3] A solar lease is also a provider-owned arrangement, not a homeowner-owned purchase. [1]
If a seller says an incentive makes the lease payment more attractive, make the claimed effect appear in the written payment and disclosure documents. Don’t subtract a personal tax credit from the lease math because it came up in a sales conversation. For a tax question tied to your own return, use current IRS guidance and a qualified tax professional, and have any lease or PPA agreement reviewed before you sign it.
Compare the retail-plan side of your Texas bill
The Real-Bill Ranking is not live yet for solar, so this page cannot compare solar leases across providers. It can help you check whether a solar quote uses honest electricity-bill assumptions. Start with your actual kWh history, use the EFL Decoder on your current plan, and keep the solar contract beside those documents.
For readers in an eligible deregulated service area such as Texas, the live comparison tool can evaluate the retail-plan side of the bill at your actual usage:
Compare Texas electricity plans at your real kWh usage. This tool compares retail electricity plans, not solar leases.
The visitor does not pay to use the electricity comparison service. ChooseMyPower may earn a referral fee if a visitor enrolls in a retail electricity plan through it. That doesn’t change the checklists above, and it doesn’t turn the pending solar tool into a live product before it is one.
Frequently asked questions
Do I own the panels in a solar lease?
No. In a solar lease, the provider owns the system and rents it to you for scheduled payments. A cash purchase or solar loan gives the homeowner ownership instead. [1]
Is a solar lease the same as a PPA?
No. Both use third-party ownership, but a lease uses a scheduled payment and a PPA charges for electricity generated at a stated price per kWh. [1]
What is an escalator clause?
It’s the contract language that raises your lease payment or PPA price over time, on a schedule set in the agreement. To see what it actually costs you, ask for the payment schedule and compare the payment (or kWh price) in the first year, a middle year, and the final year of your own contract, rather than relying on a percentage quoted verbally in a sales meeting.
The CPUC lists escalators among the disclosure items that can affect monthly payments. [1]
Will solar eliminate my electricity bill?
Don’t assume it will. Consumer guidance says solar customers may still have a utility bill, while lease and PPA customers may also have a separate provider bill. [1] Use the EFL Decoder to check the retail-plan charges and credits that remain.
What happens to a solar lease when I sell my house?
The agreement controls. Ask whether the buyer must qualify to assume it, what happens if the buyer does not qualify, and whether early termination or transfer fees apply. [1] That’s a core part of the checklist above.
What happens at the end of a solar lease term?
Your agreement has to address this somewhere in its text, typically through some combination of renewing the lease, buying the system at a price the agreement sets, or having it removed. Ask the provider to show you the exact clause rather than a verbal summary, and do it well before the term ends.
Who is responsible for maintenance and repairs on a leased system?
Leases and PPAs commonly place monitoring, maintenance, and repairs with the provider, but the homeowner remains responsible for the contract itself. [1] Get the specific service commitment in writing rather than accepting “free maintenance” as a verbal promise.
Can I use a federal residential solar tax credit with a lease?
Don’t assume so. The IRS says the individual Residential Clean Energy Credit is unavailable for property placed in service after December 31, 2025, and a lease is a provider-owned arrangement. [1] [3]
