Arizona rooftop solar laws give homeowners a strong right to install panels over any HOA objection, a 25% state income tax credit capped at $1,000, exemptions from property tax and sales tax, and a defined utility interconnection process — but they also set the ground rules for permits, licensed contractors, and how much your utility will pay for the power you export. The federal 30% Residential Clean Energy Credit expired for systems placed in service after December 31, 2025, so a system you install in 2026 relies on state incentives and bill savings alone.
Your Right To Install Under Arizona HOA Law
State law overrides any HOA covenant that would block a solar installation. An association cannot prohibit the installation or use of a solar energy device, and the statutory definition reaches photovoltaic panels, solar water heaters, and distributed generation systems.1Arizona Legislature. Arizona Code 33-1816 – Solar Energy Devices; Reasonable Restrictions; Fees and Costs2Arizona Legislature. Arizona Code 44-1761 – Definitions
Your HOA can still adopt reasonable placement rules, but those rules cannot prevent installation, impair how the device functions, restrict its use, or hurt its cost or efficiency. A rule forcing panels off a south-facing roof onto a shaded north-facing one would likely fail that test. A rule requiring black mounting hardware instead of silver would probably pass, since it has minimal effect on output or price.
If you take an HOA board to court over a violation of these solar rights and substantially prevail, the court is required to award you reasonable attorney fees and costs.1Arizona Legislature. Arizona Code 33-1816 – Solar Energy Devices; Reasonable Restrictions; Fees and Costs That fee-shifting provision is what gives the statute real teeth. You still submit plans to the architectural review committee, but what the committee can lawfully deny or burden is sharply limited.
Arizona State Tax Credit and Exemptions
Arizona offers a non-refundable state income tax credit equal to 25% of the system’s cost, capped at a lifetime maximum of $1,000 per residence. The cap is cumulative — if you claimed $600 for a solar water heater years ago, only $400 remains for a new photovoltaic system at the same address.3Arizona Department of Revenue. Arizona Form 310 – Credit for Solar Energy Devices Any portion of the credit you cannot use in the installation year carries forward for up to five consecutive years.4Arizona Legislature. Arizona Revised Statutes Title 43 Section 43-1083 You claim it on Arizona Form 310.
Two other state protections matter at least as much as the credit itself. Solar energy systems add zero value to your property for appraisal purposes, so panels can raise your home’s market value without raising your property tax bill.5Arizona Legislature. Arizona Code 42-11054 – Standard Appraisal Methods and Techniques And the purchase of solar equipment, along with the contractor’s installation labor, is exempt from Arizona’s transaction privilege tax (the state version of sales tax).6Arizona Legislature. Arizona Code 42-5159 – Exemptions On a system that runs tens of thousands of dollars, those two exemptions remove costs that would otherwise follow the system for its full life.
What Happened To the Federal Solar Credit
The Residential Clean Energy Credit under Section 25D of the Internal Revenue Code paid 30% of a system’s total cost, including equipment and labor, for installations placed in service from 2022 through December 31, 2025. Under the current statute, the credit is not available for any property placed in service after that date.7Office of the Law Revision Counsel. 26 USC 25D – Residential Clean Energy Expenditures If you installed in 2025 or earlier and could not use the full credit that year, the unused portion carries forward to your 2026 return on IRS Form 5695.8Internal Revenue Service. Form 5695 – Residential Energy Credits For a brand-new 2026 installation, no federal solar credit currently applies.
How Arizona Utilities Pay For Exported Solar
Arizona does not have traditional net metering. The two largest utilities pay a lower export rate for power you send to the grid than the retail rate you pay to pull power from it. That gap changes the economics in a specific way: a kilowatt-hour you consume directly from your panels is worth more than one you export, which pushes the design toward self-consumption and battery storage.
Arizona Public Service
APS uses a Resource Comparison Proxy rate. For the tranche running September 2025 through August 2026, the export rate is approximately 6.17 cents per kilowatt-hour.9Arizona Public Service. Rate Rider RCP – Partial Requirements Service for New Distributed Generation Customers Whatever rate applies when you interconnect stays locked in for ten years. APS resets the RCP annually, so a neighbor who connects next year could get a different number.
Salt River Project
SRP’s Time-of-Use Export Price Plan credits all exported energy at a flat 3.45 cents per kilowatt-hour regardless of time of day.10Salt River Project. Time-of-Use Export Price Plan for Solar Customers SRP also charges time-varying prices for grid power you consume: on-peak hours are 2 to 8 p.m. May through October, and 5 to 9 a.m. plus 5 to 9 p.m. November through April, with lower rates at all other times, weekends, and holidays. The spread between the export credit and peak retail prices is why SRP solar customers benefit most from shifting heavy usage to off-peak hours and from pairing panels with a battery.
Given that spread on either utility, a home battery that stores midday production for discharge during expensive peak hours is often the piece that makes the full project pencil out. Battery installations require their own permits and inspections, and the storage system has to be included in the utility interconnection application.
Permits, Fire Setbacks, and Permission To Operate
Every rooftop solar installation in Arizona needs a building permit from the local jurisdiction before work begins. The application typically calls for a site plan, an electrical diagram, and a roof plan showing existing framing. If the panel array’s distributed weight exceeds roughly four to five pounds per square foot, expect the jurisdiction to require a structural analysis from a licensed engineer.
Fire codes require clear roof pathways so firefighters can ventilate and move during an emergency. The exact numbers depend on which code your jurisdiction has adopted, but common requirements include:
- Panels set back at least one foot from all roof edges and eaves.
- An 18-inch ridge setback if panels cover a third of the roof or less, and a 36-inch setback on both sides of the ridge for larger arrays.
- At least one three-foot-wide pathway running from the gutter line to the ridge, with at least two pathways on separate roof planes and one facing the street or driveway.
These setbacks limit how many panels fit on a given roof and therefore cap system size. A good installer designs around them from the start.
After the local permit comes the utility interconnection application, which the installer submits with the contract, diagrams, and signed agreements. Once the system is built and passes local inspection, the utility runs its own field inspection to confirm the installation matches the approved plans. If it does, you get Permission to Operate and can energize the system.11Arizona Public Service. Interconnection Application Process Guide Do not turn the system on before PTO; operating without authorization creates safety hazards and can bring penalties or disconnection.
Who Is Legally Allowed To Install Solar
Arizona has no standalone solar contractor license. Solar photovoltaic work falls under the state’s electrical license classifications: C-11 (commercial electrical), R-11 (residential electrical), and CR-11 (combined). All three require a minimum of four years of experience, and any licensee performing solar work must carry a solar warranty.12Arizona Registrar of Contractors. License Classification Requirements A general contractor can manage the overall project but has to subcontract the electrical and solar portions to someone holding one of these licenses.
Before signing anything, verify the installer’s license status through the Arizona Registrar of Contractors. The ROC database shows whether a license is current and flags complaints or disciplinary history.13Arizona Registrar of Contractors. License Classifications Get bids from at least three licensed companies. Each proposal should name the panel and inverter brands, the system size in kilowatts, the projected annual production, and break out equipment, labor, and permitting costs separately. Check warranty terms carefully: panel manufacturers typically warrant equipment for 25 years, but installer workmanship warranties vary widely.
Consumer Protections For Door-To-Door Solar Sales
Solar in Arizona is often sold door to door, and specific protections apply. State law gives you a three-business-day cooling-off period to cancel most door-to-door purchases, and the seller must give you written notice of that right at the time of sale.14Arizona Attorney General’s Office. Door-To-Door Sales If the salesperson skips the disclosure, your window may extend. The FTC’s federal Cooling-Off Rule provides a parallel three-business-day right to cancel home solicitation purchases of $25 or more.
One important carve-out: the cooling-off period does not apply if you initiated the contact — for example, by inviting the salesperson over or scheduling an appointment. A door-knock that leads to a scheduled follow-up visit where you sign may fall outside the protection at that second meeting. Arizona’s Consumer Fraud Act separately prohibits unfair or deceptive practices, including misrepresentations about production, savings projections, or contract terms.15Arizona Legislature. Arizona Code 44-1521 – Definitions Many Arizona cities also require door-to-door companies to hold a peddler’s license, so asking to see that permit before you engage is reasonable.
Solar Leases and Power Purchase Agreements
If you do not want to buy a system outright, a solar lease or power purchase agreement lets a third-party company own the panels on your roof. A lease charges a fixed monthly amount. A PPA charges a per-kilowatt-hour rate for the electricity produced. Both skip the upfront cost, and both give up the state tax credit and the long-term ownership value.
The complication shows up when you sell the house. A leased or PPA system typically comes with a UCC-1 financing statement filed against the property or the equipment. Some providers will refile the UCC-1 under the buyer’s name before closing, sometimes with additional fees.16Selling Solar Homes. UCC-1 Filing and Selling Your Solar Home Whether the system is treated as a fixture that stays with the home or as personal property that can be removed depends on how the local jurisdiction classifies it. Either way, transferring the contract adds time and friction to a real estate transaction, and buyers may hesitate to take on a long-term solar contract they did not choose.
