If you’re thinking about going solar, one of the biggest decisions is not just which solar panels to install, but how you will pay for them.
The two most common choices are buying the system or leasing it. Buying means you own the solar panels and receive the long-term financial benefits. Leasing means a solar company owns the system and you pay to use the electricity it produces.
So, which saves more money?
For most homeowners who can afford the upfront cost or qualify for attractive financing, buying solar panels generally provides greater long-term savings. A lease can still make sense if you want little or no upfront cost, predictable payments, and someone else to handle maintenance.
Let’s compare the two options.
What Does It Mean to Buy Solar Panels?
When you buy a solar system, you become the owner.
You can either pay for the system with cash or use a solar loan. Once the system is paid off, you continue generating electricity without a solar financing payment.
For example, suppose a solar system costs $30,000.
If you purchase it with cash:
- You pay $30,000 upfront.
- You own the equipment.
- You don’t have a solar lease payment.
- You keep the electricity savings.
- You are responsible for maintenance, although warranties cover many components.
If you use a loan, you still own the system, but you make monthly loan payments until the loan is paid off.
EnergySage reports an average U.S. solar system cost of about $30,505 in 2026, before applicable incentives.
What Is a Solar Lease?
A solar lease works differently.
The solar company installs the panels on your property but continues to own them. You pay the company a monthly amount for the use of the system.
Most residential leases last around 20 to 25 years. The solar company typically handles monitoring, maintenance and repairs during the agreement.
For example:
Your electricity bill before solar = $200/month
Solar lease payment = $120/month
Remaining utility bill = $30/month
Your combined monthly energy cost would be:
$120 + $30 = $150
Your immediate savings would therefore be around:
$200 − $150 = $50/month
The exact numbers depend entirely on the contract and your electricity usage.
Buying vs Leasing: Quick Comparison
| Feature | Buying Solar | Solar Lease |
|---|---|---|
| Upfront cost | High with cash, potentially $0 with loan | Usually $0 |
| Own the panels? | Yes | No |
| Monthly solar payment | $0 with cash; loan payment if financed | Usually yes |
| Maintenance | Homeowner, subject to warranties | Usually solar company |
| Long-term savings | Generally higher | Generally lower |
| Home sale | Usually simpler | Can require transfer or buyout |
| Control over system | High | Lower |
| Contract length | Depends on financing | Typically 20–25 years |
| Best for | Maximum long-term savings | Low upfront cost and convenience |
Which Option Saves More Money?
If your primary goal is maximum lifetime savings, buying generally wins.
That’s because after you pay off the system, the panels can continue producing electricity for many years without a lease payment.
A lease, meanwhile, can continue requiring payments throughout the contract term.
EnergySage’s 2026 comparison says buying generally delivers higher long-term savings, while leasing provides greater capital flexibility and lower upfront costs.
Simple example
Imagine two homeowners install identical solar systems.
Homeowner A buys:
- System cost: $30,000
- Long-term electricity savings: $70,000
- Ownership: Yes
Homeowner B leases:
- Upfront cost: $0
- Lease payments over the contract: $35,000
- Electricity savings compared with the grid: $55,000
- Ownership: No
These are illustrative figures, but they demonstrate the basic principle.
Homeowner B can start with almost no upfront investment, while Homeowner A potentially keeps more of the long-term financial benefit.
The Biggest Advantage of Buying: You Own the Asset
Ownership is one of the most important differences.
Once your solar loan is completely paid off, you still own the system.
The panels can continue generating electricity, potentially reducing your energy costs for years.
You also have greater control over the equipment and what happens to the system if you sell your home.
An owned solar system can also contribute to the value and marketability of a property, although the exact impact varies by location and market conditions.
The Biggest Advantage of Leasing: $0 or Low Upfront Cost
Solar leases are attractive because you don’t have to spend tens of thousands of dollars upfront.
This can be particularly useful for homeowners who:
- Don’t have enough cash to buy solar
- Want to preserve their emergency savings
- Prefer predictable monthly expenses
- Don’t want to manage repairs
- Don’t want to take a large solar loan
According to EnergySage, leases often allow homeowners to start with little or no money down and can provide immediate electricity savings.
So leasing isn’t necessarily a bad financial decision. It is simply a different trade-off.
Watch Out for Annual Lease Increases
One of the most important things to check before signing a solar lease is the escalator clause.
Some contracts increase your monthly payment every year.
For example, suppose your starting lease payment is $120 per month and the contract includes a 3% annual increase.
Your payment could eventually become substantially higher than the original $120.
EnergySage reports that lease agreements commonly include annual escalators of around 1%–3%, although some providers offer low- or zero-escalator contracts.
A lease with a low starting payment isn’t automatically a good deal.
You need to calculate the total amount you will pay over the entire contract.
What Happens If You Sell Your House?
This is another major difference.
If you own your solar system, selling your home is generally simpler because the solar equipment belongs to you.
A leased system can require additional paperwork.
The buyer may need to assume the existing lease, or you may need to pay off or buy out the agreement before selling.
EnergySage specifically identifies lease transfers and buyouts as potential complications when selling a home.
Therefore, if you expect to move within a few years, carefully review the lease’s transfer and early-termination conditions.
Who Handles Repairs?
With a lease, the solar company generally owns the equipment and handles maintenance and monitoring during the contract.
That’s a major convenience.
With an owned system, you’re responsible for the equipment, although solar panels and other components normally come with warranties that can cover many failures.
This means leasing can be attractive to someone who doesn’t want to worry about maintenance.
You’re essentially paying for convenience as well as solar electricity.
What Changed for Solar in 2026?
The economics of solar financing changed significantly in the U.S. in 2026.
The federal residential solar tax credit ended for purchased systems installed after December 31, 2025. Solar leases and PPAs, where a third party owns the system, remain eligible for the applicable commercial solar tax credit, with providers potentially passing some of that value to customers through pricing.
That means leasing has become more financially competitive than it historically was in some situations.
However, it doesn’t automatically make leasing cheaper than buying. You still need to compare the actual contract, payment increases, savings and ownership terms.
When Should You Buy Solar?
Buying is usually the stronger option if:
- You have enough cash available.
- You plan to stay in your home for many years.
- You want maximum long-term savings.
- You want to own the equipment.
- You are comfortable handling maintenance.
- You want greater control over the system.
A solar loan can also allow you to own the system without paying the entire cost upfront.
When Should You Lease Solar?
Leasing may make more sense if:
- You don’t have enough cash for a purchase.
- You want $0 or very low upfront costs.
- You want the solar company to handle maintenance.
- You prioritize immediate monthly savings.
- You prefer predictable payments.
- You want to keep your capital available for other investments or expenses.
But always check the escalator, contract length, buyout terms and home-sale requirements before signing.
How to Compare a Solar Lease With Buying
Don’t compare only the first month’s payment.
Instead, calculate:
Total ownership cost = purchase price + financing costs + maintenance − incentives
Then compare it with:
Total lease cost = all lease payments + remaining utility bills + applicable fees
Also consider:
- Expected solar production
- Electricity-rate increases
- System degradation
- Battery costs
- Warranty coverage
- Contract escalators
- Buyout price
- Home resale implications
This gives you a much more realistic picture.
Final Verdict
Buying solar panels generally saves more money over the long term, while leasing usually wins on upfront affordability and convenience.
If you can afford to buy the system or secure a reasonable solar loan, ownership allows you to keep the long-term energy savings and eventually eliminate the solar payment.
A lease can still be a good option if you want to go solar without a large upfront investment and don’t want responsibility for maintenance.
The most important rule is simple:
Don’t choose based on the lowest monthly payment. Choose based on the lowest total cost and highest realistic lifetime savings.
A $0-down solar lease may sound attractive, but a slightly higher upfront investment can potentially leave you with a valuable owned asset and substantially greater savings over the life of the system.
