Solar Lease / PPA vs Solar Loan: 2026 Comparison
Three ways to go solar — which financing structure saves the most money over 25 years?
A solar loan is the best financial choice for most homeowners in 2026 — you claim the 30% federal tax credit, own the system, and increase your home value. Leases and PPAs eliminate upfront cost but transfer the tax credit to the installer, cap your savings at a fixed rate or set price per kWh, and can complicate home sales. Choose a lease or PPA only if you cannot qualify for a loan, lack tax liability to use the ITC, or want truly $0 involvement. If you can qualify for a solar loan, the long-term return is almost always higher.
Solar Lease / PPA vs Solar Loan — At a Glance

|---|---|---|
| Upfront Cost | $0 | $0 (most loans) |
| You Own the System | No | No (PPA same) |
| Federal ITC (30%) | Goes to installer | Goes to installer |
| Monthly Payment | Fixed lease payment | Per-kWh rate |
| Home Value Increase | No (leased equipment) | No (PPA) |
| Savings Cap | Fixed — market rate may exceed it | Rate escalates ~2–3%/yr |
| Home Sale Complication | Buyer must assume lease | Buyer must assume PPA |
| System Maintenance | Installer handles it | Installer handles it |
| Typical 25-yr Savings | $10,000–$20,000 | $12,000–$22,000 |
| Best For | No credit / no tax liability | Predictable rate desired |
When Solar Lease / PPA is the better choice
You have no federal income tax liability — if you cannot use the 30% ITC (e.g., low income, retirees on Social Security), a lease or PPA still lowers your electricity bill.
You have poor credit or cannot qualify for a solar loan — lease and PPA underwriting is less stringent, often requiring only a 650 credit score.
You want zero maintenance responsibility — under a lease or PPA, the installer owns, insures, and maintains the system for the full 20–25 year term.
When Solar Loan is the better choice
You have federal tax liability and can use the 30% ITC — on a $20,000 system, the credit is worth $6,000 directly off what you owe in taxes.
You want to maximize long-term savings — solar loan borrowers typically save $15,000–$25,000 more over 25 years than lease customers for comparable systems.
You plan to stay in your home or want to sell with a clean title — a leased system must be transferred to the buyer or bought out at sale, which can delay closings.
You want home value appreciation — studies show solar ownership adds an average of $15,000+ to resale value; leased systems do not contribute to this.
How they compare on 25-year total return
For a $20,000 6kW system: A solar loan at 6.99% over 12 years costs ~$22,400 total with payments, minus $6,000 ITC = $16,400 net cost. Your electricity savings over 25 years at $0.14/kWh average = ~$32,000. Net gain: ~$15,600 plus ~$15,000 in home value. A lease for the same system at $120/mo costs $36,000 over 25 years, saving $45,000 in electricity — net gain $9,000 with no home value increase. A PPA at $0.09/kWh rising 2.5%/yr: in year 25 you pay $0.16/kWh — above average utility rates — meaning savings evaporate in the final years. The solar loan wins on total return in almost every realistic scenario.

Customer reviews and reputation
Solar leases and PPAs are offered by major national companies including Sunrun, SunPower, and Tesla Solar. Solar loans are provided by specialty lenders (GreenSky, Mosaic, Dividend) and some traditional banks. Leases and PPAs are recorded as UCC liens on your property — review this carefully before signing, as it appears in a title search and must be addressed at home sale.
Frequently Asked Questions
Common questions about Solar Lease / PPA vs Solar Loan.
Is a solar lease better than a solar loan?
A solar loan is better financially for most homeowners — you own the system, claim the 30% federal tax credit, and save 2–3x more over 25 years. A lease is better only if you cannot qualify for a loan or have no tax liability to use the ITC.
What is the difference between a solar lease and a PPA?
A solar lease charges a fixed monthly payment regardless of production. A PPA (power purchase agreement) charges per kilowatt-hour of electricity actually produced. Both transfer system ownership to the installer.
Who gets the federal solar tax credit on a lease?
The installer gets the 30% federal ITC when you lease or sign a PPA — you do not own the system so you cannot claim it. With a solar loan or cash purchase, you claim the full credit directly on your taxes.
What happens to my solar lease when I sell my house?
You must either transfer the lease to the buyer (requires their credit approval and the installer consent) or buy out the remaining lease value at closing. This can complicate or delay home sales.
Can I get a solar loan with bad credit?
Some specialty solar lenders require 640+ FICO. GreenSky and Mosaic offer programs down to 600 in some cases. Lease and PPA providers typically require 650–680. For credit below 640, a lease or PPA may be your only option.
Does a leased solar system add value to my home?
Generally no — appraisers and buyers view leased systems as a liability (transferred debt obligation) rather than an asset. Owned solar systems add an average of $15,000+ to home value per Lawrence Berkeley National Laboratory research.
