The solar panels stay on the roof. The payment, ownership and contract can become part of your next home sale.
For homeowners in Surprise and the Phoenix West Valley, choosing solar means comparing more than an electric bill. Paying cash, taking a loan and signing a lease create different costs and responsibilities. Buyers considering a home with existing solar need to understand those same differences.
Before you sign, answer three questions: What will solar cost while you live here? Who owns the equipment? What happens when you sell?
Solar lease vs. buy: cash, loans and ownership
Owning solar does not necessarily mean it is paid off. Start by identifying both the equipment owner and any remaining financial obligation.
Buy with cash
You own the system. A fully paid cash purchase avoids loan interest and monthly solar financing payments.
Tradeoff: A significant upfront expense, plus repairs and maintenance outside warranty coverage.
Ask: Will realistic savings justify the cost over the years I expect to own this home?
Buy with a loan
You own the system, subject to financing terms. Payments spread out the purchase cost and preserve cash.
Tradeoff: Interest, fees and a remaining balance that needs attention when selling.
Ask: What are the cash price, financed price, total payments and early-payoff terms?
Lease the system
The provider owns the equipment. You pay for its use under a contract, often with little upfront cost.
Tradeoff: A long-term agreement, possible payment increases and transfer requirements.
Ask: Who covers repairs, and what happens if I move or the system underperforms?
Compare the ownership structures in the Department of Energy's homeowner solar guide.
A low loan rate can hide a higher purchase price. Request cash and financed quotes for the identical equipment. The CFPB has documented dealer fees added to solar loan balances and payment increases when an expected lump-sum payment is not made. Read the CFPB solar financing report.
Fixed solar leases vs. escalator leases
A fixed-payment lease, often described as having a 0% escalator, keeps the scheduled lease payment level during the stated term. Your utility bill can still change.
An escalator lease increases the payment according to the contract. A 2.9% annual increase compounds: each increase applies to the previous year's payment. It does not depend on your utility increasing its rates by the same amount.
See Solar United Neighbors' explanation of leases and escalators.
| Contract year | Fixed payment | 2.9% annual increase |
|---|---|---|
| Year 1 | $150/mo. | $150/mo. |
| Year 5 | $150/mo. | $168/mo. |
| Year 10 | $150/mo. | $194/mo. |
| Year 15 | $150/mo. | $224/mo. |
| Year 20 | $150/mo. | $258/mo. |
| Year 25 | $150/mo. | $298/mo. |
| 25-year lease payments | $45,000 | $64,772 |
Illustration only. One increase follows each completed year; totals use unrounded payments. Figures exclude utility bills, upfront charges, taxes and other contractual costs. Actual competing quotes may have different starting payments.
If you sell in year ten, the buyer evaluates the payment in year ten and the increases still ahead. Ask for the complete payment schedule before committing.
A PPA charges differently
With a power purchase agreement, you generally pay for the electricity produced, measured in kilowatt-hours. A fixed price per kilowatt-hour does not guarantee a fixed monthly bill because production varies. PPAs may also have rate escalators. Check whether you must buy all production, including power exported to the grid. The EPA explains how PPAs work.
Compare your solar payment and remaining utility bill
APS confirms that grid-connected solar customers continue receiving utility bills. Your rate plan, usage and credits for exported electricity affect the result. Review APS solar and billing guidance.
An average $90 utility bill plus a $180 solar payment equals $270 per month. That calculation shows monthly cash flow. Evaluating the full investment also requires counting upfront cash, applicable maintenance, insurance and equipment replacement costs.
Example only; these figures are not Arizona household averages or a savings forecast.
Review at least 12 months of utility bills alongside actual solar production. Account for air-conditioning efficiency, thermostat settings, occupancy, EV charging and pool equipment. A nearby home of similar size may use a very different amount of electricity.
For homes with pools: If the pool operated throughout the billing period, its electricity use is already reflected in those bills. Adding another estimated pool expense would count it twice.
Do solar panels increase home value in Arizona?
There is no automatic dollar-for-dollar increase. A system's installation price and remaining loan balance do not establish what a buyer will pay for it.
Ownership, system condition, documented performance and market evidence matter. Under Fannie Mae's rules, leased and PPA equipment cannot be included in the property's appraised value. Separately financed systems have additional requirements. The lender needs accurate ownership and financing documents. See Fannie Mae's solar property requirements.
From a Realtor's perspective, clear records make the feature easier to evaluate. A buyer should be able to understand the equipment, energy costs and obligations without guessing.
Selling a house with solar panels: loans and transfers
- Paid-off equipment: Confirm ownership, warranty transfer and any related title matters.
- Financed equipment: Request a current payoff. Verify whether the lender permits a transfer; never assume a buyer will take over the loan.
- Leased or PPA equipment: Obtain written transfer requirements, buyer qualification criteria and any purchase or prepayment options.
Resolve these details with the solar provider, lender and title company early. If a payoff will come from your proceeds, include it in your estimated seller net.

Buying a house with leased solar panels: what to review
Request these records before accepting an existing solar arrangement. The checklist also applies to owned systems with financing.
- The complete agreement: Include the purchase, loan, lease or PPA contract and amendments.
- The payment schedule: Confirm today's payment, the remaining term and future increases.
- Transfer and payoff details: Obtain current written requirements and any applicable quotes.
- Utility and production history: Review at least 12 months and ask about downtime.
- Equipment and warranties: Check installation dates, service history and monitoring access.
- The roof: Confirm its condition and who pays to remove and reinstall panels for roof work.
Send the agreement to your mortgage lender early. Solar obligations can affect qualification depending on the contract and loan program; the lender should determine how they apply to your purchase.

Solar tax credits: check the rules for your installation year
Older articles often advertise a 30% federal homeowner credit. The IRS states that the Residential Clean Energy Credit is unavailable for property placed in service after December 31, 2025. Do not deduct that credit from the cost of a new 2026 installation. Check the current IRS guidance.
State incentives and incentives available to system providers have separate rules. Have your tax professional verify what applies before relying on an incentive in your budget.
Common Arizona homeowner questions
Is solar worth it in Arizona?
It depends on the installed price, financing or lease terms, actual production, utility rates and how long you keep the home. Compare the full cost with a credible estimate of electricity costs without solar. Sunshine alone does not determine the financial outcome.
Does a prepaid solar lease mean I own the panels?
No. Prepaying can eliminate scheduled lease payments while the provider retains ownership. Buying the equipment is a separate contractual step. Confirm exactly what transfers with the house. See Solar United Neighbors' prepaid lease guidance.
Which option makes the most sense if I may move soon?
Compare the expected savings before your move against upfront costs, the remaining loan balance and any lease transfer or buyout requirements. Ask each provider for the terms that would apply in the year you expect to sell.
