Solar Lease vs. Buy: Which Option Is Right for Your Arizona Home?

Going solar is one of the smartest investments a Tucson homeowner can make, but deciding how to pay for it can be just as important as the decision to go solar in the first place.

The two most common paths are buying your solar panel system outright (or with a loan) and leasing it from a solar company. So, the next logical question is this: is it better to buy or lease solar panels?

Each option has real trade-offs when it comes to long-term savings, upfront costs, maintenance, tax incentives, and what happens when you sell your home. This guide breaks down the solar lease vs. buy decision so you can choose the financing option that fits your situation.

How Buying Solar Panels Works

When you purchase a solar panel system, you own the equipment on your roof. You can pay with cash upfront or finance the purchase through a solar loan.

Cash purchase: You pay the full system cost (typically $20,000 to $35,000 before incentives for a residential installation) and start generating electricity bill savings from day one. There are no monthly payments, and every kilowatt-hour (kWh) your panels produce is money back in your pocket.
Solar loan: You finance the system over 5 to 25 years with fixed monthly payments. Many homeowners find that their electricity bill savings exceed their loan payment right away, creating positive cash flow from the start. Once the loan is paid off, the savings are entirely yours for the remaining life of the system.

In both cases, you hold full system ownership, which means you qualify for state tax credits, you control maintenance decisions, and your solar panels increase your home’s value.

How Does a Solar Lease Work?

With a solar lease, a solar company installs and owns the panels on your roof. You pay a fixed monthly lease payment to use the electricity they produce, typically with zero down payment required.

A closely related option is a power purchase agreement (PPA). Instead of a flat monthly fee, you pay a set rate per kWh of electricity the system generates.

Both solar leases and PPAs are forms of third-party ownership (TPO), meaning the solar company retains ownership of the equipment throughout the contract term (usually 20 to 25 years).

Solar panel lease cost typically falls between $75 and $250 a month, but be aware that most lease agreements include an escalator clause that increases your monthly payment by 1% to 3% each year.

Maintenance, monitoring, and repairs are generally handled by the leasing company, and many contracts include a performance guarantee that the system will produce a minimum amount of energy.

Solar Lease vs. Buy: How They Compare

Understanding how these options stack up across the factors that matter most will help you make a confident decision.

Long-Term Savings

Buying solar panels delivers the highest return over time. Once your system is paid off (whether immediately with cash or after your loan term), every dollar of electricity your panels generate is pure savings.

Typical payback periods range from 7 to 12 years, and panels produce power for 25 years or more.

With a solar lease, you save money compared to your regular utility bill, but a significant portion of those savings goes to the leasing company. Over a 25-year period, system owners typically save tens of thousands of dollars more than leaseholders.

Upfront Costs

Buying requires a larger initial investment. Even with a solar loan, you may need to meet credit requirements and potentially cover a down payment.

A lease, on the other hand, usually requires zero down payment, making it accessible to homeowners who don’t have the cash on hand or prefer not to take on debt.

Solar Tax Credits and Incentives

This is one of the biggest differences. When you own your system, you can benefit from the $1,000 Arizona solar tax credit, a property tax exemption (solar panels will not increase your property tax), and a sales tax exemption on the purchase.

When you lease, the solar company owns the system and claims these incentives, as well as the Federal Solar Investment Tax Credit for commercial applications (expires July 2026), instead of you. You do not directly receive any tax credits, Renewable Energy Certificates (RECs), or state rebates.

Home Value and Resale

Owned solar panels consistently increase home resale value. Studies show that homes with purchased solar systems sell for a premium, and the sale process is straightforward because the system is part of the property.

Leased solar panels add little to no value to your home. If you sell before the lease ends, the new buyer must either qualify to assume the lease transfer or you’ll need to negotiate a lease buyout, which can cost thousands of dollars and complicate the sale.

Solar Maintenance and Repairs

Leasing has an advantage here. The solar company handles all operations and maintenance, inverter replacements, and repairs for the duration of the contract. If something breaks, it’s their responsibility.

When you own the system, solar panel maintenance falls on you. However, most quality solar panel systems come with 25-year manufacturer warranties and 10 to 15-year inverter warranties, so out-of-pocket repair costs are uncommon. Many solar installers also offer service agreements that cover routine solar maintenance services.

Monthly Payments

With a cash purchase, there are no monthly payments. With a solar loan, you will have fixed payments that often align with or are less than your previous electricity bill.

Lease payments start lower, but escalator clauses mean they rise over time. After 15 to 20 years, your monthly lease payment could exceed what you would have paid for grid electricity, potentially eliminating any savings in the later years of the agreement.

Solar Lease vs. PPA vs. Loan: What’s the Difference?

It’s worth understanding all three financing options:

Solar lease: Fixed monthly payment to rent the system, regardless of how much electricity it produces.
Solar PPA: You pay per kWh of electricity generated, so your monthly cost varies with production.
Solar loan: You borrow money to buy the system. You own it, claim all incentives, and pay off the loan over time.

For most Arizona homeowners, a solar loan offers a stronger financial outcome than a lease or PPA because you still benefit from tax credits and long-term ownership savings, even if you cannot pay cash upfront.

When Leasing Solar Panels Makes Sense

A solar lease can be the right choice if:

You cannot secure a solar loan due to credit requirements.
You do not have the upfront cash and prefer a completely hands-off experience with no maintenance responsibility.
You plan to move within a few years and want lower electricity costs without a large financial commitment.

When Buying Solar Panels Is the Better Option

Purchasing solar panels is typically the stronger financial decision if:

You can pay cash or qualify for a solar loan.
You want to maximize your long-term savings and take full advantage of the state solar tax credit and other Arizona solar incentives.
You plan to stay in your home for several years or more.
You want to increase your home resale value.
You want full control over your solar energy system and the freedom to modify or expand it.
You are financially prepared to handle all maintenance needs and solar system repairs if necessary.

Arizona-Specific Considerations

Arizona is one of the best states for solar, and Tucson homeowners have access to incentives that make buying especially attractive:

Arizona Residential Solar Tax Credit: Up to $1,000 off your state income tax.
Property tax exemption: Your solar system will not increase your assessed property value for tax purposes.
Sales tax exemption: No sales tax on solar equipment purchases.
Net billing: Sell excess energy back to the grid and receive credits on your electricity bill, reducing costs even further.
300+ days of sunshine: Tucson’s abundant solar resource means faster payback periods and higher lifetime savings compared to most of the country.

With these incentives stacked together, the financial case for buying a solar panel system in Arizona is strong. Leasing still reduces your electricity bill, but you leave a significant amount of money on the table by giving up the tax credits and ownership benefits.

Make the Right Solar Decision for Your Home

Whether you choose to lease or buy, going solar in Tucson will lower your electricity costs and reduce your environmental footprint. For most homeowners, purchasing a system, whether with cash or through solar panel financing, delivers the best long-term return.
