Solar Financing Compared: Purchase vs. Lease vs. PPA

Thinking of going solar in Tucson (or nearby in Arizona)? Let’s break down your solar financing options so you can choose what fits your goals, budget, and long-term strategy — whether that's ownership, third-party control, or financing through a loan.

Buying Solar: Cash, Loan, or Refinance

• Cash Purchase
  • Pros:
    • You own the system outright.
    • Eligible for the full federal Investment Tax Credit (30% in Arizona) and any local rebates (e.g., up to $1,000 in AZ) 
    • Maximum long-term savings.
  • Cons:
    • High upfront cost.
• Solar Loan
  • Pros:
    • Low or zero down, customized for solar—no home appraisal or mortgage required 
    • Same ownership benefits as cash—tax credits, increased home value, long-term energy cost reduction 
  • Cons:
    • Monthly loan payments; savings take time to accumulate (though many loans offer attractive terms).
• Refinance / HELOC
  • Pros:
    • May offer lower interest than unsecured loans.
  • Cons:
    • More paperwork, often requires appraisal, and shifts debt to your home as collateral.

ROI Estimate (Example Scenario):

• System cost: $25,000 → ITC savings at 30% = $7,500 → net cost = $17,500.
• With a local utility rate increase (e.g., 3–5% annually) and zero maintenance, payback can occur in ~6–8 years. After loan payoff, electricity is essentially free, accelerating long-term ROI.

Solar Lease

• You rent the equipment and pay a fixed monthly fee for solar energy 
• Maintenance, monitoring, and repairs are handled by the provider.
• You don’t own the panels, and they control tax incentives.
• Monthly payments may include annual escalators — often still less than utility bills At lease end (20–25 years), you may:
  • Extend the lease,
  • Buy the system (if contract allows), or
  • Have panels removed.

Best For:

• Homeowners who want hassle-free solar with predictable monthly costs, limited budget, and no desire to own.

ROI:

• Typically yields lower lifetime savings than owning — you don’t benefit from tax incentives or full asset value

Solar Power Purchase Agreement (PPA)

• The installer installs and owns the system; you pay per kWh produced—like buying electricity directly from your own panels 
• Payments fluctuate based on production (seasonal variability) and may include escalators Benefits: No maintenance, no system ownership responsibilities.
• Drawbacks: No tax credits to you, variable monthly cost.

When PPA Outperforms Lease:

• In regions with high, consistent sunshine (like Tucson), PPAs can yield greater seasonal savings, especially if you use most of the solar output 

Side-by-Side Comparison

Why Advanced Electric & Solar Is Ideal for Purchasers

• Partnered Low-Interest Solar Loans: Specifically tailored for local residents, easier than HELOCs or second mortgages 
• Arizona Incentives: Pair the 30% federal ITC with possible $1,000 state rebate—boosts ROI significantly. The federal Investment Tax Credit (ITC) for residential solar is currently 30%, thanks to extensions under the Inflation Reduction Act—and systems installed before December 31, 2025 qualify. This window is closing fast, so acting now can lock in substantial savings
• Top Tucson Installer Since 2013: Renowned for personalized service, reliability, and attention to detail 

Which Option Fits You Best?

• Looking for maximum savings and benefits? → Buy with cash or a solar loan—you profit long-term, leverage incentives.
• No upfront cost and worry-free upkeep? → Lease offers predictability without ownership responsibilities.
• Prefer paying per actual energy produced with seasonal cost variation? → PPA may give better value in sunny regions like Tucson.
