Arizona Solar in 2026: The Honest Picture

Arizona is one of the sunniest states in the nation, with an average solar irradiance of 5.8 kWh/m2/day. That advantage translates to strong energy production and meaningful savings for homeowners who go solar. However, 2026 brings a significant change: the federal Residential Clean Energy Credit (Section 25D) expired on December 31, 2025, for systems placed in service after that date. This shifts the financial equation.

The good news is that Arizona has stepped up with its own incentives. The state offers a 25% income tax credit (capped at $1,000 per year), a 100% property tax exemption on solar equipment, and a sales tax exemption. Major utilities like Arizona Public Service (APS) and Salt River Project (SRP) also run rebate programs. These state and local incentives, combined with Arizona’s exceptional solar resource, still make solar a solid investment for most homeowners.

The challenge is that Arizona does not have traditional net metering. Instead, APS and SRP use net billing, which credits excess solar production at a lower rate than what you pay for grid electricity. This reduces long-term savings compared to states with full net metering. Understanding this trade-off is essential before you commit.

This guide walks you through Arizona solar costs, realistic savings scenarios, available incentives, and how to choose a qualified installer.

Average Solar System Cost in Arizona (2026)

A typical 6 kW residential solar system in Arizona costs approximately $26,500 before incentives. This breaks down roughly as follows:

  • Equipment (panels, inverter, racking, wiring): $14,000 to $16,000
  • Labor and installation: $8,000 to $10,000
  • Permitting and interconnection: $1,500 to $2,500
  • Monitoring and warranty: $500 to $1,000

System size varies by household energy use. A 5 kW system might cost $22,000; an 8 kW system could run $35,000. Roofing condition, shading, and local labor rates also affect pricing. According to EnergySage cost benchmarks, Arizona’s per-watt cost ($4.40 to $4.80 after tax incentives) is slightly below the national average, reflecting the state’s mature solar market and competitive installer base.

After applying Arizona’s state tax credit (up to $1,000 per year), property tax exemption, sales tax exemption, and utility rebates (typically $500 to $2,000), your net out-of-pocket cost can drop by $5,000 to $8,000 in year one, with additional tax credits spreading over subsequent years.

Real Arizona Homeowner Savings (Sample Scenarios)

Savings depend on your location, utility, electricity rate, and system size. Here are four realistic scenarios based on 2026 rates:

Phoenix (APS service area, 6 kW system): Annual electricity bill: $1,800 Annual solar production: 10,500 kWh Annual savings (net billing): $1,200 to $1,350 25-year savings: $28,000 to $32,000 Payback period: 8 to 9 years

Scottsdale (APS service area, 6 kW system): Annual electricity bill: $1,950 Annual solar production: 10,800 kWh Annual savings (net billing): $1,300 to $1,450 25-year savings: $31,000 to $36,000 Payback period: 8 to 9 years

Tucson (TEP service area, 6 kW system): Annual electricity bill: $1,600 Annual solar production: 10,200 kWh Annual savings (net billing): $1,050 to $1,200 25-year savings: $24,000 to $29,000 Payback period: 9 to 11 years

Mesa (APS service area, 5 kW system): Annual electricity bill: $1,500 Annual solar production: 8,750 kWh Annual savings (net billing): $950 to $1,100 25-year savings: $22,000 to $27,000 Payback period: 9 to 10 years

These estimates assume stable electricity rates and no major roof replacement during the system’s 25-year lifespan. Net billing rates vary by utility and time-of-use period, so ask your installer for a utility-specific quote.

Arizona Solar Incentives Still Available in 2026

Arizona Residential Solar and Wind Energy Systems Tax Credit

Arizona offers a state income tax credit equal to 25% of the cost of a residential solar system, with a maximum credit of $1,000 per tax year. This credit applies to both purchased and leased systems, though the rules differ slightly. If your system costs $10,000, you can claim $2,500 in credits, but you receive only $1,000 in year one; the remaining $1,500 carries forward to future tax years. This multi-year structure is important for budgeting.

Property Tax Exemption for Solar Equipment

Arizona exempts 100% of the added home value from solar equipment from property tax assessment. If your solar system adds $30,000 to your home’s market value, that $30,000 is not subject to property tax. This exemption applies indefinitely as long as you own the system. It is one of Arizona’s strongest solar incentives and significantly improves the long-term return on investment.

Sales Tax Exemption on Solar Equipment

Arizona exempts solar equipment and installation labor from sales tax. On a $26,500 system, this saves approximately $2,100 in sales tax (assuming 7.9% average rate). This exemption is automatic; your installer should apply it at the point of sale.

APS Solar Rebate Program

Arizona Public Service (APS) offers rebates ranging from $0.50 to $1.25 per watt for residential solar systems, depending on the program tier and system size. A 6 kW system might qualify for $3,000 to $7,500 in rebates. Rebates are paid directly to the installer or homeowner after system inspection and approval. APS also offers time-of-use (TOU) rate plans that can increase solar savings if you shift consumption to peak solar production hours.

SRP Solar Incentive Program

Salt River Project (SRP) provides rebates up to $2,000 for residential solar systems in its service area. SRP also offers a “Solar Partner Program” for customers interested in community solar, though individual rooftop systems remain the most common choice. Check SRP’s website for current program details and eligibility.

Is Solar Worth It in Arizona Without the Federal Credit?

The expiration of the federal Residential Clean Energy Credit (Section 25D) changes the calculus, but solar remains economically viable in Arizona for most homeowners. Here is why:

Arizona’s state incentives are substantial. The 25% tax credit, property tax exemption, and sales tax exemption together reduce your net cost by $5,000 to $8,000 in the first year. Over 25 years, the property tax exemption alone saves $8,000 to $12,000 in avoided property taxes.

Arizona’s solar resource is exceptional. At 5.8 kWh/m2/day, Arizona ranks in the top tier nationally. This means your system produces more electricity per installed watt than systems in most other states, shortening payback periods.

Payback periods remain reasonable. In Phoenix and Scottsdale, a typical 6 kW system pays for itself in 8 to 9 years. In Tucson and Mesa, payback stretches to 9 to 11 years. Both are acceptable for a system with a 25-year warranty and lifespan.

Net billing is a trade-off, not a deal-breaker. APS and SRP credit excess solar production at roughly 60% to 80% of retail rates. This is lower than full net metering, but it still provides meaningful savings. Always request a detailed net billing estimate from your installer before signing a contract.

The only federal option in 2026 is a third-party lease. If you want to access a federal tax benefit, you must use a third-party-owned solar lease under Section 48E. The company must begin construction before July 4, 2026. Leases typically offer lower upfront costs but lock you into a fixed payment and you forfeit state incentives. For most Arizona homeowners, purchasing with state incentives remains the better path.

Decision framework:

  • If you plan to stay in your home 7+ years, buy.
  • If you have a strong tax liability and can use the state credit, buy.
  • If you want to avoid upfront cost and do not mind a fixed payment, lease (but verify the company qualifies under Section 48E).
  • If you have a poor credit score or limited cash, a lease may be your only option.

  • Flagstaff: 5.2 kWh/m2/day, APS service area, higher elevation and winter cloud cover reduce production, but still viable for year-round residents.

What to Look for in an Arizona Solar Installer

  1. Licensing and bonding. Verify that the installer holds a current Arizona Contractor License (ROC license) and carries general liability and workers’ compensation insurance. Check the Arizona Registrar of Contractors website.

  2. Experience with your utility. Ask how many systems the installer has completed for APS, SRP, or your local utility. Familiarity with interconnection timelines and net billing rules matters.

  3. Transparent pricing. Request a detailed written quote that itemizes equipment, labor, permitting, and incentives. Avoid installers who quote only “after-incentive” prices without breaking down the gross cost.

  4. Warranty coverage. Confirm that the installer offers at least a 10-year workmanship warranty and that panels and inverters carry manufacturer warranties (typically 25 years for panels, 10 to 15 years for inverters).

  5. References and reviews. Ask for at least three local references and check Google, Yelp, and the Better Business Bureau. Look for patterns in customer satisfaction, not isolated complaints.

  6. Financing options. Compare cash, loan, lease, and power purchase agreement (PPA) options. Understand the terms, interest rates, and how each affects your eligibility for state incentives.

  7. Post-installation support. Confirm that the installer monitors your system for the first year, handles warranty claims, and provides ongoing technical support. A responsive installer is worth the premium.

Get Free Quotes From Vetted Arizona Installers

Solar costs and incentives change frequently. The best way to understand your specific savings is to request quotes from multiple Arizona installers. Compare pricing, warranty terms, and financing options side by side. Most reputable installers offer free consultations and quotes with no obligation.

When you request quotes, provide your recent electricity bills so installers can size your system accurately and model your savings under your utility’s specific net billing structure. Ask each installer to itemize the state tax credit, property tax exemption, sales tax exemption, and utility rebates so you understand the true cost and payback period.

Arizona’s solar market is mature and competitive. Taking time to compare installers and incentives will save you thousands of dollars and help you avoid costly mistakes.
