Solar Tax Credit in 2026: Why Only Lease & PPA Options Qualify

What Changed with the Solar Tax Credit?

The federal Investment Tax Credit (ITC) still exists at 30% — but as of 2026, it no longer applies to homeowner-purchased solar systems. The credit is now exclusively available to the system owner, which in a TPO (Third-Party Ownership) arrangement means the solar company, not you. When you lease a system or sign a PPA (Power Purchase Agreement), the solar company owns the equipment, claims the 30% tax credit, and passes the savings to you in the form of lower monthly payments.

• The 30% ITC still exists — but only for system owners
• Homeowner cash purchases and loans no longer qualify
• TPO companies (lease/PPA providers) claim the credit on your behalf
• Lower monthly lease/PPA payments reflect the tax credit savings
• This change took effect for systems installed after January 1, 2026

What Is TPO (Third-Party Ownership)?

TPO means a solar company owns the panels on your roof and you pay them a fixed monthly rate for the electricity produced. There are two main TPO structures:

• Solar Lease: Fixed monthly payment regardless of production — simple and predictable
• PPA (Power Purchase Agreement): You pay per kWh produced — typically $0.08-$0.15/kWh, well below utility rates
• Both options: $0 down, maintenance included, 20-25 year terms
• The solar company owns the system, claims tax credits, handles maintenance
• You benefit from lower electricity costs without owning the equipment

How TPO Passes Tax Credit Savings to You

When a TPO provider installs a $30,000 system on your roof, they claim the 30% ITC ($9,000) on their own taxes. This reduces their cost basis, which allows them to offer you lower monthly payments than if there were no credit. In practice, this means your lease or PPA rate is 20-30% lower than it would be without the ITC. You don't file any tax forms — the savings are baked into your monthly rate automatically.

Should You Choose Lease, PPA, or Cash Purchase?

With the tax credit no longer available for direct purchases, the financial calculus has shifted. Here's how to think about it:

• Lease/PPA: Lower upfront commitment, tax credit benefits passed through, maintenance included — ideal for most homeowners
• Cash purchase: You own the system outright, highest long-term savings, but no tax credit — best for homeowners who want maximum control
• Loan: Similar to cash purchase (you own it), but with financing — no tax credit applies
• Sunlink offers all options so you can compare side-by-side with transparent pricing

What This Means for Your Solar Decision

The removal of the homeowner tax credit doesn't make solar a bad investment — electricity rates are still rising 2-5% per year, and solar still locks in your energy cost for 25+ years. It does mean that lease and PPA options are now relatively more attractive compared to cash purchases. Sunlink's platform lets you compare all financing options side-by-side with real pricing, so you can see exactly which option saves you the most over time.
