Solar incentive makes Arizona’s 300+ sunny days even more valuable by helping homeowners save thousands through tax credits, state rebates, and utility programs when installing solar panels.

What Are Solar Incentives?

Solar incentives are financial programs designed to reduce the upfront cost of solar panel installation. These include tax credits, rebates, and exemptions that make renewable energy affordable for Arizona homeowners.

You can often combine multiple incentives on the same project. For example, a $25,000 solar system in Chandler might gain a 35-40% reduction in cost after all incentives.

Important: Solar incentive programs can change based on legislation. Always verify the current tax credit status before installation.

Types of Solar Incentives

Arizona homeowners can benefit from multiple solar incentives like federal, state, and property-tax related that work together to significantly reduce the overall cost of going solar.

Federal Solar Tax Credit (Investment Tax Credit - ITC)

The federal solar Investment Tax Credit reduces your federal income tax based on your total solar installation cost.

What's Covered:

  • Solar panels and inverters

  • Solar charge controller and mounting equipment

  • Wiring and labor costs

  • Permits and inspection fees

  • Solar battery storage systems

How It Works: If you install a $25,000 solar system and qualify for a 30% credit, you receive $7,500 off your federal tax bill. Consequently, you can carry forward the remaining credit to future tax years.

Arizona State Solar Tax Credit

Arizona offers 25% of your installation cost up to a maximum $1,000 credit on your state income tax.

The Arizona credit maxes at $1,000 regardless of system size. Thus making it especially valuable for smaller residential installations.

Arizona Property Tax Exemption for Solar Energy

When you add solar to your Arizona home, the increased property value does not increase your annual property tax assessment.

Example: Your $350,000 home with a $25,000 solar system might increase in market value to $370,000, but your property taxes remain based on the original $350,000 valuation.

Benefits:

  • Save thousands in property taxes over 25+ years

  • Higher resale value without an ongoing tax burden

  • Automatic exemption, no special paperwork required

Sales Tax Exemption on Solar Equipment

Arizona exempts solar energy devices from the 5.6% state sales tax on both equipment and installation labor.

For a $25,000 installation, you save approximately $1,400 upfront, and this isn't money you claim back later. It's simply not charged.

Arizona Utility Solar Incentives and Net Metering

Arizona's major utilities like APS (Arizona Public Service), SRP (Salt River Project), and TEP (Tucson Electric Power) offer net metering programs that make solar even more valuable.

How Net Metering Works: When your solar panels produce more electricity than you use, excess power flows back to the power grid. Your meter runs backward, earning you credits on your electric bill that you can use at night or on cloudy days.

Example: Your Litchfield Park home produces 40 kilowatt-hours on a sunny Saturday but only uses 20. Those extra 20 kilowatt-hours earn credits for later use.

Utility-Specific Programs:

  • APS: Net metering with "export rates" for excess solar

  • SRP: Customer Generation Price Plan with solar-specific rate schedules

  • TEP: Net metering at retail rates for Tucson-area homeowners

Utilities occasionally offer rebate programs for solar installations or battery storage. Check with your specific utility for current offerings.

Solar Renewable Energy Credits (SRECs) in Arizona

SRECs are certificates representing the environmental benefits of generating solar electricity (one certificate per 1,000 kilowatt-hours produced).

Arizona has a Renewable Energy Standard, but the SREC market is limited compared to other states. Most utilities meet requirements through large-scale solar projects rather than purchasing from homeowners.

Some Arizona homeowners may have opportunities depending on their utility. Ask your installer about current SREC programs, though income potential is modest for residential systems.

Do Solar Battery Storage Qualify for Incentives?

Solar battery storage systems qualify for the same federal tax credit as solar panels. In addition, batteries provide backup power during monsoon storms and grid outages.

What Qualifies:

  • Installed with solar panels (simultaneously or added later)

  • Minimum 3 kilowatt-hours capacity

  • Charged primarily by solar panels (at least 75%)

Who Qualifies for Arizona Solar Incentives?

  • Ownership: You must own your solar system outright. Leasing transfers all tax benefits to the leasing company, not you.

  • Residence: System must be on your primary or secondary Arizona residence. Vacation homes qualify, but rental properties where you don't live typically don't.

  • Tax Liability: You need sufficient federal and state tax liability to benefit. Credits reduce what you owe, but don't create refunds. Moreover, unused credits carry forward to future years.

  • New Installation: Incentives apply to new installations only, not used equipment.

  • Documentation: Keep itemized invoices, permits, inspection certificates, and contractor licenses for at least seven years.

How to Claim Arizona Solar Incentives?

Here’s how you claim a solar incentive in Arizona:

  1. Complete solar panel installation with licensed contractor. Obtain detailed documentation.

  2. Collect all paperwork like invoices, permits, inspection certificates, and equipment specs.

  3. File IRS Form 5695 (Residential Energy Credits) with your federal tax return.

  4. File Arizona Form 310 (Solar Energy Credit) with your state tax return.

  5. Verify sales tax exemption was applied to your invoice.

  6. Consult a tax professional for complex situations or carry-forward credits.

  7. Store all solar-related documents for at least seven years.

Incentives for Solar Panel Installation vs. Solar Shingles

Both traditional solar panels and solar shingles qualify for identical federal and state incentive programs. The IRS and Arizona don't distinguish between technologies.

What's the Same:

  • Federal tax credit percentage

  • Arizona's $1,000 state credit maximum

  • Sales tax exemption (5.6% savings)

  • Net metering programs

  • Property tax exemption

Example: A Gilbert homeowner installing $35,000 in solar shingles receives the same credits as someone installing $35,000 in traditional panels.

The choice between panels and shingles comes down to aesthetics, roof condition, and personal preference, but not incentive differences.

How Solar Incentives Affect Your Solar Investment?

Solar incentives dramatically improve your return on investment by reducing payback periods and increasing long-term savings.

  • Payback Period: Without incentives, solar might take 12 to 15 years to pay for itself. However, with incentives reducing costs by 30 - 40%, the payback drops to 6 to 10 years.

  • Monthly Savings: A Surprise homeowner saving $150 monthly saves $1,800 annually, or $45,000 over 25 years.

  • Rate Protection: Arizona utility rates have increased 3 to 5% annually. Solar locks in your energy costs, protecting you from future hikes.

  • Home Value: Solar panels increase home values by $15,000 to $20,000 on average. Furthermore, combined with a property tax exemption, you get this boost without paying extra taxes.

  • System Performance: Incentives make solar affordable upfront, but proper maintenance ensures decades of savings. 

Common Mistakes Arizona Homeowners Make With Solar Incentives

  1. Not Claiming Both Credits: Some homeowners claim federal credits but forget Arizona's $1,000 state credit. Thus, file both forms together.

  2. Leasing Instead of Buying: Leases transfer all tax benefits to the leasing company. Buying, even with a loan, provides far better returns.

  3. Missing Documentation: Without proper invoices and permits, you can't prove expenses. Thus, keep everything organized.

  4. Not Verifying Sales Tax Exemption: Some contractors incorrectly charge sales tax. Thus, review invoices before final payment.

  5. Failing to Register for Net Metering: Your system can't earn credits until registered with your utility. Hence, verify registration is complete.

  6. Not Understanding Carry-Forward Rules: Unused credits carry forward to future years. Therefore, consult a tax professional.

  7. Assuming Old Information Is Current: Incentive programs change regularly. Therefore, always verify current availability before installation.

Frequently Asked Questions

  1. What is the income limit for the solar incentive?

There are no income limits for federal or Arizona solar incentives. Anyone can qualify, but you must have enough tax liability to use the credit. Unused federal credits roll forward to future years until fully applied.

  1. Will the government pay for your solar panels?

No, the government doesn’t pay for solar panels. However, they offer solar incentives that can reduce your tax bill. Firstly, you pay for installation upfront, and then you can claim credits over time. Moreover, unused credits carry forward. However, you don’t receive cash refunds.

  1. Can you claim solar incentives on a second home?

Yes, federal solar credits apply to second homes you personally use. Arizona credits require part-time occupancy. Rental properties generally don’t qualify. 

  1. What happens to solar incentives if I sell my house?

Claimed credits stay with you and never transfer to the buyer. Buyers gain the system’s energy benefits, while you keep the tax savings received during ownership.

  1. How do I know if I qualify for solar incentives?

You qualify if you own the system, install it on a U.S. residence, have tax liability, use new equipment, and place it in service that tax year. However, leased systems don’t qualify.
