Solar lease cost vs buying compared for 2026 — real monthly lease payments ($50–$150/mo), 25-year cost projections, what the expired federal tax credit changes, and which option saves more.
Going solar is one of the smartest financial moves a homeowner can make in 2026 — but how you go solar matters just as much as whether you do it. The difference between leasing and buying can mean tens of thousands of dollars over 25 years, and the right choice depends entirely on your financial situation.
Let's cut through the sales pitches and look at real numbers. Solar companies love to throw around "zero down" and "save from day one" — and while those things can be true, they don't tell the whole story.
How Solar Leasing Works
When you lease solar panels, a company installs a system on your roof and you pay a monthly fee to use the electricity it generates. You don't own the panels — the leasing company does. There are two main structures:
- Solar Lease: Fixed monthly payment ($50–$150/month) regardless of how much energy the panels produce. Simple and predictable.
- Power Purchase Agreement (PPA): You pay per kilowatt-hour of electricity the panels produce, typically at a rate 10–30% below your utility's rate. Your bill varies with production.
Both typically come with 20–25 year contracts. Most include an annual escalator of 1–3% — meaning your payments increase each year. This is the detail that catches people off guard. That $100/month lease becomes $130–$160/month by year 15 if it has a 2.5% escalator.
How Much Does It Cost to Lease Solar Panels Per Month?
This is the number most people want first. Solar lease cost depends on system size, your local sun exposure, and whether the contract has an escalator. Here's what monthly solar lease payments typically look like in 2026:
| System Size | Monthly Lease (Year 1) | With 2.5% Escalator (Year 15) | Best For |
|---|
| 4 kW (small home) | $50–$75 | $72–$108 | 1–2 person household |
| 6 kW (average home) | $75–$110 | $108–$159 | Typical 3-bedroom home |
| 8 kW (large home) | $100–$140 | $144–$202 | 4+ bedrooms, high usage |
| 10 kW (very large home) | $130–$175 | $187–$252 | Large home, EV charging |
The average homeowner leasing a 6–8 kW system pays roughly $75–$140 per month in year one. The catch is the escalator: a 2.5% annual increase means your payment climbs about 45% over a 15-year window. Always ask whether the lease is fixed or escalating before you sign — a fixed-payment lease costs slightly more at the start but is far more predictable.

How Buying Works
Buying means you own the system outright. You can pay cash or finance with a solar loan. Here's what each looks like:
- Cash Purchase: $15,000–$25,000 upfront for a typical 8kW residential system. Highest total savings, fastest payback.
- Solar Loan: $0 down, monthly payments of $100–$200 for 10–20 years. You still own the system and get all the tax benefits.
Buying used to carry a big advantage here: the federal Residential Clean Energy Credit (§25D) covered 30% of system costs — $6,000 on a $20,000 system — and only owners could claim it. That credit was terminated by Public Law 119-21 for expenditures made after December 31, 2025, so it no longer favors either option. Ownership's remaining advantages are equity, added home value, and the lower total cost of power over 25 years.
25-Year Cost Comparison
| Metric | Lease/PPA | Solar Loan | Cash Purchase |
|---|
| Upfront Cost | $0 | $0 | $18,000–$22,000 |
| Federal Tax Credit | Not eligible | $5,400–$6,600 | $5,400–$6,600 |
| Monthly Cost (Year 1) | $80–$130 | $120–$180 | $0 |
| Total Paid (25 years) | $30,000–$50,000 | $18,000–$28,000 | $18,000–$22,000 |
| Total Savings (25 years) | $10,000–$25,000 | $25,000–$50,000 | $40,000–$65,000 |
| Payback Period | Immediate (lower bill) | 7–12 years | 5–8 years |
| Owns System | No | Yes | Yes |
The numbers don't lie — buying wins on total savings by a wide margin. But leasing isn't automatically a bad deal. Context matters.
Impact on Home Value
This is where things get really interesting. Studies from Zillow and the Lawrence Berkeley National Laboratory show that owned solar panels increase home value by $15,000–$20,000 on average. Buyers love a home with no electric bill.
Leased panels? That's a different story. Many buyers see a lease transfer as a liability — they're inheriting a 15-year contract they didn't negotiate. Some buyers walk away entirely, and others demand a price reduction. If you're planning to sell within 10 years, this is a major consideration.
Contract Gotchas to Watch For
- Escalator clauses: That 2.5% annual increase means your "savings" shrink every year as your lease payment rises while utility rates may not climb as fast.
- Early termination fees: Canceling a solar lease can cost $5,000–$20,000+. Read the fine print carefully.
- Roof maintenance: Need a new roof? You'll have to pay the leasing company $2,000–$5,000 to remove and reinstall their panels.
- Performance guarantees: Make sure your lease guarantees minimum energy production. If the panels underperform, you should pay less.
- End of lease: What happens at year 25? Some contracts auto-renew, some require you to buy the aging system, and some remove the panels free of charge. Know your options upfront.
Monthly Savings: A Real Example
Let's say your current electric bill is $200/month and you're looking at an 8kW system in a sunny state. Here's how each option shakes out in year one:
- Lease: Electric bill drops to ~$20/month, lease payment is $100/month. Net savings: $80/month.
- Solar Loan: Electric bill drops to ~$20/month, loan payment is $150/month. Net cost increase: $30/month (but you own the system).
- Cash Purchase: Electric bill drops to ~$20/month. Net savings: $180/month from day one.
After the loan is paid off (typically year 10–12), loan buyers save the full $180/month for the remaining 13–15 years. That's where ownership pulls way ahead. For more on energy costs and savings, check our HVAC replacement cost guide for additional ways to cut your utility bills.
Who Should Lease vs Buy?
Leasing Makes Sense If:
- You want $0 down and no responsibility for the equipment
- Your credit score makes solar loans expensive (above 8% APR)
- You're renting your home or planning to move within 3–5 years
- You want zero hassle and don't care about maximizing savings
Buying Makes Sense If:
- You qualify for a solar loan at 4–7% APR or can pay cash
- You plan to stay in your home 7+ years
- You want maximum long-term savings and increased home value
- Your state or utility offers incentives that only owners can claim
For most homeowners in 2026, buying with a solar loan is still the sweet spot — no money down, you own the system, and your savings exceed a lease within roughly 6–9 years. That crossover used to come faster; the 30% federal credit that accelerated it expired for systems completed after 2025, so ownership takes a little longer to pull ahead. Cash buyers save the most overall, but tying up $20,000 isn't feasible for everyone.
Whatever route you choose, get quotes from at least 3–4 solar companies and compare the total cost over 25 years — not just the monthly payment. That's where the real picture becomes clear. For other energy-saving upgrades, browse our HVAC system comparison guide.
Frequently Asked Questions
Q. How much does it cost to lease solar panels per month?
In 2026, leasing solar panels typically costs $50–$175 per month depending on system size. A small 4 kW system runs about $50–$75 a month, an average 6 kW system $75–$110, and a large 8–10 kW system $100–$175. Most leases include a 1%–3% annual escalator, so payments rise over the life of the contract.
Q. Is it cheaper to lease or buy solar panels?
Buying is cheaper over the long run. Across a 25-year span, a leased system costs $30,000–$50,000 in total payments, while a purchased system costs $18,000–$28,000. Buying used to win by even more, because owners could claim the 30% federal tax credit and lessees could not — that credit expired for systems completed after 2025, so ownership's advantage is now purely in the total cost of the electricity. Leasing has a lower barrier to entry ($0 down) but the lowest total savings.
Q. What is the difference between a solar lease and a PPA?
A solar lease has a fixed monthly payment regardless of how much energy the panels produce. A power purchase agreement (PPA) charges you per kilowatt-hour of electricity generated, usually at a rate 10%–30% below your utility's. With a lease your bill is predictable; with a PPA it varies with sunshine and production.
Q. Can I get the solar tax credit if I lease?
There is no federal solar tax credit to get on a 2026 installation, leased or owned. The 30% Residential Clean Energy Credit (IRC §25D) was ended by Public Law 119-21 for expenditures made after December 31, 2025, and the expenditure counts as made when installation is completed. Before that, the credit went to whoever owned the system, so lessees never got it and buyers did — worth $5,400–$6,600 on a typical system. If your system was completed in 2025 or earlier and you own it, you can still claim it on that year's return. See the IRS Home Energy Tax Credits page.
Q. Does leasing solar panels make it harder to sell my home?
It can. Buyers often see a leased solar contract as a liability they didn't negotiate, and some will ask for a price reduction or walk away. Owned solar panels, by contrast, raise home value by an average of $15,000–$20,000. If you plan to sell within 10 years, buying is the safer choice.
