The main ways to pay for solar
Cash purchase – You own the system outright, capture all incentives and avoid interest. Best total lifetime savings if you can afford the upfront cost.
Solar panel loans – $0 down options spread costs over 10 to 25 years. You still own the system, claim incentives and build equity while paying a monthly installment.
Solar leases – A third party owns the system. You pay a fixed monthly lease. Low upfront cost and simple maintenance, but you do not claim tax credits.
Power purchase agreements (PPAs) – You pay per kWh produced at an agreed rate. No ownership and no tax credits for you, but potentially the lowest upfront commitment.
| Option | Ownership | Upfront | Monthly | Incentives | Maintenance |
|---|---|---|---|---|---|
| Cash | You | High | None | You claim | You |
| Loan | You | Low to $0 | Fixed | You claim | You |
| Lease | Provider | Low to $0 | Fixed | Provider | Provider |
| PPA | Provider | Low to $0 | Per kWh | Provider | Provider |

How to choose the best solar loan
- Compare APR and total cost – Factor in dealer fees and origination costs, not just the headline rate.
- Pick a fitting term – 10 to 20 years lowers monthly payments as term increases, but raises total interest.
- Check prepayment rules – Prefer loans with no prepayment penalty so you can apply rebates or bonuses later.
- Plan your tax credit – Many homeowners make a principal payment when they receive the 30% tax credit.
- Understand liens – Some lenders file a UCC-1 on equipment. Home equity loans use your home as collateral.
When comparing offers, use 3D solar simulations in proposals to support ROI and payback calculations that guide financing choices.
Secured vs unsecured solar loans
Secured loans use collateral. Common options include home equity loans or HELOCs, which typically offer lower APRs and possible tax-deductible interest, but place your home at risk if you default. Some secured solar loans also file a property or equipment lien. Unsecured solar loans are installment loans that rely on your credit profile without home collateral. They are faster to approve and often available through banks, credit unions and dedicated solar financing companies, but usually have higher APRs or dealer fees. Choose secured if you want the lowest rate and are comfortable with collateral. Choose unsecured for speed and simplicity.
Incentives, tax credits and $0 down offers
The federal solar Investment Tax Credit equals 30% of eligible residential and commercial solar costs. Many states and utilities add rebates, performance incentives or low interest programs. With loans, you usually claim incentives yourself. With leases and PPAs, the provider claims them and bakes value into your price. $0 down solar can mean a $0 down loan, a lease, or a PPA. Interest free solar loans typically refer to short promotional periods or financing with embedded dealer fees. Government or utility loans may exist locally through green banks or utility on-bill programs. Always confirm eligibility with a tax professional.
Moving, selling and buyouts
Owned systems can increase home value and help listings stand out. If you financed with a loan, you can usually pay off the balance at sale or, in limited cases, allow a qualified buyer to assume it. With a solar lease or PPA, you typically transfer the agreement to the buyer after credit approval, or you can request a buyout per your contract terms. Gather documents early – system specs, warranties, production data and financing details – to streamline appraisals and buyer due diligence.
FAQs
Do solar companies offer financing?
Yes. Most installers partner with residential solar financing companies, banks or credit unions to offer solar power loans, $0 down solar, and sometimes lease or PPA programs. You can also seek bank loans for solar panels independently.
Is the 30% solar tax credit going away in 2026?
Under current law, the 30% federal tax credit runs through 2032. It is scheduled to step down afterward unless extended. Check the latest IRS guidance and consult a tax advisor.
What is the difference between a lease and a PPA?
In a lease you pay a fixed monthly amount for use of the system. In a PPA you pay a set price per kWh produced. In both cases the provider owns the system and claims incentives.
