- Costs and savings depend on your home; compare system size, upfront price or lease payment, utility credits, and assumptions behind long-term estimates.
- Arizona offers several solar incentives, including a state tax credit of up to $1,000 for eligible residents; export credits vary by utility and plan.
Tucson Electricity Prices
Electricity prices have climbed in Arizona, making local rate trends useful context when evaluating solar in Tucson.
Statewide Arizona residential electricity averaged 12.5¢ per kilowatt-hour in 2021 and 14.9¢ in 2024. The U.S. average rose from 13.7¢ to 16.5¢ over the same period; these are state and national figures, not Tucson-specific rates.
For Tucson households, rooftop solar can supply some daytime electricity and reduce how much power is purchased from the utility. The effect depends on system size, household use, and the utility’s rules for billing and exported energy.
Over time, generating part of your own electricity may help limit exposure to changing grid prices. Any long-term value depends on installation costs, system performance, utility rates, and how much solar power the home uses.
Price of Energy: Arizona vs National Average
Tucson Area Utility Providers
For Tucson households served by Tucson Electric Power (TEP), the latest figures provided are for 2023: electricity cost 15.0¢ per kWh. That is below the 2023 U.S. average of 16.0¢ and above Arizona’s 14.00¢ average.
These benchmarks place TEP between Arizona’s and the nation’s averages. They show how its per-kWh rate compares, but the figures alone do not identify what drives differences among utility rates.
Solar can offset some electricity bought from TEP, making the utility rate one factor in evaluating a system. The actual value depends on household energy use and system details, so these rates alone cannot determine savings.

Arizona Solar Incentives
For Tucson homeowners, state and local programs can help offset solar costs. Explore the solar incentives in Arizona listed below.
Options include a state income-tax credit, a sales-tax exclusion for qualifying equipment, and property-tax valuation treatment. Utility export credits vary by provider and rate plan; APS and TEP customers may also find seasonal battery rewards.
The federal 30% residential credit was eliminated by the Big Beautiful Bill. With LightReach leasing, Palmetto handles the commercial ITC and passes savings through as lower monthly payments.
| Incentive | Type | Description | Source |
|---|---|---|---|
| Arizona Credit for Solar Energy Devices (Form 310) | State Income-Tax Credit | Arizona residents may claim a credit of 25% of qualifying solar-device costs, up to $1,000 per residence, with unused credit generally carried forward for up to five consecutive years. | Learn More |
| Arizona Solar-Equipment Transaction Privilege Tax (TPT) Treatment | Sales-Tax Exemption / Deduction | The qualifying retail sale of a solar energy device may be excluded from the applicable Arizona TPT tax base when sold through a properly registered solar-energy retailer. | Learn More |
| Arizona Property Valuation Treatment for On-Site Solar | Property-Tax Valuation Exclusion | Qualifying on-site solar energy equipment is treated as adding no value to the property for appraisal purposes, reducing the risk that the solar system increases assessed property value. | Learn More |
| Arizona Solar Export Compensation and Interconnection Tariffs | Net Billing / Net Metering / Export Compensation | Arizona has no single statewide solar export rate; bill credits and compensation depend on the customer’s utility, rate plan, tariff, and sometimes interconnection history. | Learn More |
| TEP Energy Storage Rewards | Battery Demand-Response Reward | Qualifying TEP residential customers can earn $120 per average kW per season for battery participation, with potential rewards across summer and winter seasons. | Learn More |
An Arizona resident who is not claimed as another taxpayer’s dependent may claim a credit equal to 25% of the cost of a qualifying solar energy device installed at the resident’s Arizona home, up to a maximum of $1,000. The $1,000 limit is cumulative for the same residence, rather than a new limit for each system.
Claim the credit using Arizona Form 310 and Form 301. Unused credit may generally be carried forward for up to five consecutive tax years. A solar system that includes storage may qualify, but a stand-alone battery is not clearly covered; check the current instructions or consult ADOR or a tax professional. See ADOR Form 310 information and A.R.S. § 43-1083.
Arizona law provides favorable TPT treatment for qualifying retail sales of solar energy devices. The practical benefit is potential avoidance of applicable transaction privilege tax on the qualifying equipment purchase; the exact tax treatment depends on the transaction and the retailer’s status.
This is not a blanket exemption for every installation, labor, or contracting charge. Confirm that the seller is registered as required and ask how the exemption is reflected on your invoice. See A.R.S. § 42-5061 and ADOR contracting guidance.
Arizona law provides that qualifying on-site solar equipment is considered to add no value to the property for appraisal purposes. This can help prevent a qualifying solar installation from increasing the property’s assessed value and resulting property-tax valuation.
This is a valuation rule, not a cash rebate or a direct reduction in the home’s existing assessed value. The law covers specified solar devices and grid-tied photovoltaic systems primarily used to produce energy for on-site consumption; do not assume a stand-alone battery receives the same treatment. See A.R.S. § 42-11054.
Tucson homeowners should check TEP’s current tariff before sizing a solar system: export compensation is utility- and plan-specific, and new customers generally should not assume they will receive retail-rate net metering. TEP describes Resource Comparison Proxy (RCP) net-billing arrangements that credit excess generation at an applicable purchase rate; qualifying legacy customers may have different terms.
Check the current terms, rates, interconnection requirements, and enrollment status directly with TEP: TEP RCP and SRP solar plan comparison.
TEP offers a performance-based reward of $120 per average kW per season. TEP estimates that a battery contributing an average of 3 kW could earn about $360 in a season, or up to $720 across two seasons, depending on performance and program terms. This is not an upfront purchase rebate.
Participants must be TEP residential customers with a qualifying connected battery, matching account and service-address information, reliable internet, and permission for the manufacturer to adjust battery charging and discharging settings. Supported equipment and event participation rules apply; customers may opt out of events. Check current details at TEP Energy Storage Rewards.

How to Choose a Solar Installer in Tucson
Verify the license
Paid residential solar installation in Arizona generally requires an appropriate contractor license. Solar-device installers must meet the applicable solar-contractor qualifications, and the right license classification depends on the work. Ask each bidder for the Arizona license number and the exact business name responsible for the installation, then confirm the license and scope with the Arizona Registrar of Contractors (AZ ROC) before signing. Arizona’s licensing law is available here; the supplied information does not include an AZ ROC lookup link.
Look for certified installers
NABCEP certification can indicate that an individual has met a solar-industry credential’s requirements; it is a useful qualification to compare, not a replacement for an Arizona contractor license. You can learn about credentials at NABCEP. Ask what certification the person designing or supervising your system holds and who will actually be on site. Manufacturer certifications may show that an installer has completed training or meets that manufacturer’s requirements. Ask what a specific certification covers, and don’t treat it as a guarantee of workmanship or system performance.
Compare quotes the same way
Request itemized written proposals with matching assumptions. Compare:
- System size: proposed capacity in kW and the price per watt, calculated on the same basis.
- Equipment: panel and inverter brands and models.
- Expected output: estimated production in kWh per year and the assumptions behind the estimate.
- Warranties: panel product and performance, inverter, workmanship, and roof penetrations; note who handles claims.
- Project responsibilities: who obtains permits, schedules inspections, and submits the utility interconnection application.
- Payment: total cost or monthly payment, financing or lease terms, and any escalator. Compare payment structures separately from system price.
If a proposal leaves out an item, ask for it in writing rather than assuming another bid includes the same thing.
Permits, interconnection and your HOA
Building and electrical permits and inspections are handled by the local authority having jurisdiction; the correct office and requirements depend on your property address. The homeowner or installer applies to the serving electric utility for interconnection and an agreement. In the Tucson area, utilities may include Arizona Public Service Co, Salt River Project, Tucson Electric Power Co, or UNS Electric, Inc.; confirm the provider for your address. Requirements can differ, and an interconnection agreement is required before connecting for utilities under Arizona Corporation Commission jurisdiction.
Arizona law limits HOA and covenant restrictions on rooftop solar: planned-community associations cannot prohibit solar devices and may set only reasonable placement rules that do not prevent installation or impair function, use, cost, or efficiency. Effectively prohibiting covenants are generally void, subject to an exception for instruments entered into before April 17, 1980. These protections do not create an easement over a neighbor’s property. See A.R.S. § 33-1816.
Red flags
- Pressure to sign the same day or claims that an offer will disappear before you can compare it.
- An unlicensed contractor, or out-of-state crews without a clear explanation of the Arizona-licensed contractor responsible for the work. Ask who employs and supervises the crew.
- Vague production estimates, or reluctance to explain assumptions and equipment choices.
- A large upfront deposit without a clear written schedule of payments and project milestones.
- Promises of federal homeowner tax credits for purchases in 2026; homeowner credits ended December 31, 2025.
For workmanship, abandonment, licensing, or unlicensed-contractor concerns, contact the AZ ROC. For deceptive or unfair sales, advertising, or business practices, consumers can also complain to the Arizona Attorney General’s Consumer Information and Complaints Unit.
Leasing Solar Panels
For Tucson homes served by Tucson Electric Power (TEP), Palmetto lists a solar lease as available. Availability depends on your address and utility. With a lease, you pay a set monthly amount; a power purchase agreement (PPA), by contrast, charges for each kilowatt-hour the system produces. A PPA is not listed as available for Tucson.
Leasing can mean installing solar without paying the full system cost upfront. The leasing provider owns the panels and, under the agreement, handles covered system maintenance—unlike a cash purchase, where you own the equipment and arrange upkeep yourself.
Lease payments are generally fixed, while PPA charges can rise and fall with seasonal production. Compare the tradeoffs in this guide to buying or leasing solar, and learn about Palmetto LightReach.
Go solar without the investment
With LightReach, there are no investment costs to recoup, loan payments to manage, or maintenance needs to take on. As soon as your panels are active, your solar savings are too!

Tucson has solar export credits, but most new Tucson Electric Power (TEP) customers do not receive traditional 1:1 net metering. Under TEP’s net-billing arrangement, exported electricity is credited at the applicable rate; the current listed rate is 6.33¢ per kWh.
For new TEP customers, that export rate is generally locked for 10 years after interconnection. Any remaining credits are reviewed during the September billing period: balances over $10 are trued up, while smaller balances roll over unless you request a check. Confirm current terms with TEP.
Yes—owned solar panels may increase a Tucson home’s resale value. Zillow found homes with solar sold for about 4.1% more on average, though that national result is not a guarantee for any Tucson property. The value can depend on system condition, energy production, and utility rules.
This potential value applies to systems the homeowner owns, not leased or other third-party-owned (TPO) systems. With a lease, a buyer may need to assume the agreement, which can affect resale differently. Read the Zillow study.
In Tucson, the LightReach lease offers a low fixed monthly payment with no upfront cost. The calculator estimates $77–$142 per month depending on home size, including $105 per month for a medium home.
Cash-purchase estimates range from $16,824 to $29,726; a medium-home system is estimated at $22,405 after the Arizona incentive. The federal 30% tax credit is no longer available for residential cash purchases following the 2025 federal law change. See the calculator above for estimates specific to each home size.
With a solar lease, the provider owns the panels and you pay a set monthly amount instead of buying the system upfront. In Tucson, an 8.20 kW system is estimated at about $105 per month; actual terms depend on your home and agreement.
Palmetto’s LightReach lease includes installation, monitoring, maintenance, and a protection program with a 90% Production Guarantee. There is no upfront cost, and the lease payment is typically less than the electricity bill it helps offset, so savings may begin when the system is active.
Palmetto Solar is a solar installation option for Tucson homeowners. We’ve completed 13,443 installations in Arizona since 2020 and work with an installation network to serve local communities.
When comparing an installer, check how the system design accounts for your roof, shade, air-conditioning use, and Tucson Electric Power’s export-credit rules. We offer financing options, so Tucson residents can compare payment approaches alongside system estimates and contract terms.
Solar panels are low maintenance in Tucson. Rain may wash away some dust, but desert dust can build up and affect output, so check panels and system performance periodically; follow the installer’s guidance for cleaning and inspections.
With LightReach, Palmetto owns the system and handles maintenance, monitoring, and repairs at no extra cost. The agreement also includes a 90% Production Guarantee.
Yes. Solar panels work well in Tucson’s sunny climate, which averages about 6.5 peak sun hours per day. They also generate some electricity on cloudy days, though output is lower when clouds block direct sunlight.
Production changes with the seasons: longer, sunnier days generally boost output, while shorter winter days reduce it. Tucson’s summer monsoon clouds, dust, and extreme heat can also affect production, so monthly output varies.
