How to Finance Solar Panels in Arizona in 2026 (Without the Federal Credit)

Without the 30% federal solar tax credit, the upfront cost of solar is higher than it's been in years. But Arizona homeowners still have several smart financing options that make solar pencil out — even at full price.

Option 1: Cash Purchase

Paying cash gives you the best long-term return because you avoid interest payments entirely. For an 8 kW system at $2.85/W, that's roughly $22,800 out of pocket (minus $1,000 AZ state credit = $21,800 net).

Payback period: 9-12 years
25-year savings: $30,000-$45,000 (depending on rate increases)
Best for: Homeowners with available savings who plan to stay in their home 10+ years

Option 2: Solar Loan

Solar loans are the most popular financing option in Arizona. Most local credit unions and solar lenders offer 10-25 year terms with rates from 4.5% to 8.5% APR.

$0 down — Start saving from month one
Monthly payment: $120-$200/month for an 8 kW system (15-year loan)
Key advantage: Your monthly loan payment is often less than your current APS bill savings, meaning you're cash-flow positive from day one
Watch out for: Dealer fees (some installers mark up loan costs 15-30%). Ask for the cash price vs. financed price — and negotiate

Option 3: Solar Lease / PPA

With a lease or Power Purchase Agreement (PPA), a third-party company owns the panels on your roof and you pay a fixed monthly rate or per-kWh price for the power they produce.

$0 down, $0 maintenance — The company handles everything
Lower savings: You typically save 10-20% on electricity vs. 50-80% with ownership
Contract length: 20-25 years with annual escalators (1-3%/year)
Resale complication: The lease transfers to the new buyer, which can complicate home sales
Best for: Homeowners who want immediate savings with zero risk and don't mind lower overall returns

Option 4: PACE Financing (Property Assessed Clean Energy)

PACE loans attach to your property tax bill, not your personal credit. Arizona has active PACE programs in many municipalities.

No personal credit check — Qualification based on property equity and tax payment history
Long terms: Up to 25 years
Transfers with property: If you sell, the remaining balance transfers to the new owner
Higher rates: PACE rates are typically 6-9%, higher than the best solar loans
Best for: Homeowners who can't qualify for traditional solar loans

The Smart Play: Solar Loan + Battery

Here's the 2026 meta: finance your solar with a low-rate loan, and add a battery. The battery still qualifies for the 30% federal ITC, APS offers a $3,750 rebate, and VPP earnings generate $150-$500/year in passive income.

The battery incentives effectively subsidize the overall system cost, making the combined solar + battery package more attractive than solar alone — even without the solar ITC.
