Solar Power in Mesa
Mesa’s intense sunshine can make rooftop solar worth exploring—but the right system depends on more than clear skies. Roof condition, shade, household energy use, and utility rules all shape how a solar installation in Mesa is designed and connected. Requirements can vary by service area, so checking which utility serves your home is an important early step.
This guide walks through the installation process and key choices Mesa homeowners may encounter. For a primer on equipment, see our guide to home solar panels.

Key Takeaways
- Mesa’s sunshine is only part of the solar picture—roof condition, shade, energy use, and utility rules also affect system design and value.
- Local estimates put an 8.2 kW system at about $22,405 after the listed state incentive, but actual costs and savings vary by home.
- APS and SRP have different solar billing rules, so check your utility’s current export rates and incentives before choosing a system.
Mesa Electricity Prices
Arizona electricity rates have climbed in recent years, making the cost of powering a Mesa home worth a closer look.
The chart shows Arizona’s average residential rate rising from 12.5 cents per kilowatt-hour in 2021 to 14.9 cents in 2024. Actual bills and rates vary by utility, plan, and household use.
A rooftop solar system can generate electricity at home and reduce how much a household buys from the grid. In Mesa, SRP or APS may serve a home, depending on its address, and their billing rules differ.
Over time, solar can help limit exposure to grid-rate increases, though results depend on system costs, energy use, sunlight, and utility policies. Reviewing those factors can clarify its potential long-term value.
Price of Energy: Arizona vs National Average
Mesa Area Utility Providers
Mesa homes may receive electricity from APS or SRP. The latest utility figures provided are from 2023, not 2024: APS averaged 15.3¢ per kWh and SRP 12.5¢ per kWh.
In 2023, APS’s rate was above Arizona’s 14.0¢ average but below the U.S. average of 16.0¢. SRP’s rate was below both. Electricity costs can vary by utility and plan.
Because costs depend on the provider and plan, solar’s value can differ across Mesa homes. Generating some electricity at home may help households manage utility costs, though results depend on individual circumstances.

Arizona Solar Incentives
Mesa residents may find state and utility incentives that help offset solar costs. See the solar incentives in Arizona listed below.
Arizona offers an income-tax credit, qualifying sales-tax and property-valuation treatment, and utility-specific export compensation. Eligible APS and TEP customers may also earn seasonal rewards for battery participation.
Federal 30% residential tax credit ended under the Big Beautiful Bill; state and local incentives remain. LightReach leasing has Palmetto handle commercial ITC and pass savings through lower 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 |
| APS Storage Rewards Pilot | Battery Demand-Response Reward | Eligible APS residential customers can earn $110 per average kilowatt of battery contribution for the May–October season through performance-based conservation-event rewards. | 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.
Arizona homeowners should check their utility’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. APS describes Resource Comparison Proxy (RCP) net-billing arrangements that credit excess generation at an applicable purchase rate; qualifying legacy customers may have different terms. SRP uses its own price plans, which can include within-billing-cycle netting or fixed export credits.
SRP also has a separate Renewable Export Program for qualifying facilities of 100 kW AC or less. It may offer a capacity credit for customers who enroll under the program and commit to delivering capacity during an eligible period; it is not an automatic credit for every solar customer. Check the current terms, rates, interconnection requirements, and enrollment status directly with your utility: APS renewable riders, SRP solar plan comparison, and SRP Renewable Export Program.
APS states that participants can earn $110 per average kW their battery provides during the season. For example, an average contribution of 3 kW would earn $330 for the season. This is a performance-based reward, not an upfront battery-purchase rebate.
Applicants must be APS residential rate-plan customers, have an APS-approved battery and permission to operate, and meet the program’s equipment and enrollment requirements. Events take place during the May–October season, and customers may opt out of individual events. Batteries without solar may qualify. Confirm current equipment eligibility and program terms with APS Storage Rewards.

How to Choose a Solar Installer in Mesa
Verify the license
Paid residential solar installation in Arizona generally requires an appropriate contractor license. Solar-device installers must meet applicable solar-contractor qualifications, and the right classification depends on the work. Ask each bidder for the Arizona Registrar of Contractors (AZ ROC) license number and confirm with the AZ ROC that the license and classification fit the proposed scope before signing. Arizona’s licensing law is available in A.R.S. § 44-1762. If different companies will handle different parts of the job, ask which licensed contractor is responsible for each part.
Look for certified installers
NABCEP certification can be a useful credential to compare, but ask which person holds it and what work or role it covers. You can review certification information at NABCEP. Also ask whether the installer has certifications from the manufacturers of the panels or inverters in your quote, and what those certifications cover. Treat certifications as additional information—not a substitute for confirming the appropriate Arizona contractor license.
Compare quotes the same way
Put proposals side by side and ask each installer to clarify differences. Compare:
- System size: the proposed capacity in kilowatts (kW).
- Price: total price and price per watt, with any included or excluded work identified.
- Equipment: panel and inverter brands and models.
- Production: estimated electricity generation in kilowatt-hours per year (kWh/year), plus the assumptions behind each estimate.
- Warranties: panel product and performance, inverter, workmanship, and roof penetrations; ask who handles warranty claims.
- Responsibilities: who applies for permits, schedules inspections, and handles the utility interconnection application and agreement.
- Payment: total cost or monthly payment, and any escalator or other change to scheduled payments.
Permits, interconnection and your HOA
Building and electrical permits and inspections are handled by the local authority having jurisdiction; the exact office and requirements depend on your property address. The homeowner or installer applies to the serving electric utility for interconnection and an agreement. Ask which utility serves the address—Arizona Public Service Co, Salt River Project, Tucson Electric Power Co, or UNS Electric, Inc. may have different processes; municipal electric systems may also have different requirements. For utilities under Arizona Corporation Commission jurisdiction, an interconnection agreement is required before connecting.
Arizona law limits HOA and covenant restrictions on rooftop solar. Planned-community associations cannot prohibit solar devices, though reasonable placement rules are allowed if they do not prevent installation or impair function, use, cost, or efficiency. Covenants that effectively prohibit solar are generally unenforceable, subject to an exception for instruments entered into before April 17, 1980. These rules do not create an easement over neighboring property. See A.R.S. § 33-1816 and A.R.S. § 33-439.
Red flags
- Pressure to sign the same day or before you can review the proposal.
- Unlicensed crews, or out-of-state crews when the bidder cannot identify the appropriately licensed Arizona contractor responsible for the work.
- Vague production estimates without a clear annual kWh figure or explanation.
- A large upfront deposit without a clear written schedule of payments and work.
- Promises that you can claim a federal homeowner tax credit for a 2026 purchase; homeowner credits ended December 31, 2025.
Leasing Solar Panels
For Mesa, AZ homeowners served by SRP or APS, Palmetto lists solar leasing as available; a PPA is not listed as an option. A lease has a set monthly payment, while a PPA charges for each kilowatt-hour the system produces. Learn more about buying vs. leasing solar.
Leasing can make solar installation possible without paying the full system cost upfront. Palmetto owns the system and handles maintenance, so you don’t need to manage upkeep yourself as you would with a cash purchase. Review your agreement for the specific terms and coverage.
Explore Palmetto LightReach and consider how a lease payment fits your budget, electricity use, and utility plan.
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!

Mesa does not have one citywide net-metering rate. Most homes are served by APS or SRP, and both use net billing: electricity sent to the grid earns credits, usually at a rate below the retail price of power.
APS’s listed export credit is $0.06857 per kWh, locked for 10 years after interconnection. SRP credits vary by solar rate plan and time of year, generally $0.02–$0.06 per kWh; unused credits can carry forward. Check your utility and current tariff for exact terms.
Solar panels may increase a Mesa home’s resale value, but no increase is guaranteed. Zillow’s study found homes with solar panels sold for about 4.1% more; this is a national finding, not a Mesa-specific estimate. Arizona’s property-tax valuation rules are separate from a home’s market sale price.
This potential value increase applies to owned systems, such as purchased panels. Leased or TPO systems may affect resale differently because the buyer may need to assume the lease agreement.
In Mesa, LightReach solar leasing offers a low fixed monthly payment with no upfront cost. The calculator estimates $77 per month for a small home, $105 for a medium home, and $142 for a large home.
Cash purchase is another option. The calculator estimates $16,824–$29,726 after the listed Arizona incentive, including $22,405 for a medium home. The federal 30% residential solar tax credit is no longer available for cash purchases following the 2025 law change. See the calculator above for specific pricing.
With LightReach, Palmetto owns and installs the solar system; you pay monthly, with no upfront cost. In Mesa, an 8.20 kW system is estimated at $105/month, using Arizona’s 1,624 kWh/kW production ratio and a $0.095/kWh rate.
The payment includes panels, installation, monitoring, maintenance, comprehensive protection, and a 90% production guarantee. Palmetto claims the commercial 30% ITC and passes savings through as lower payments. If your lease costs less than your current power bill, savings may start at activation.
In Mesa, a typical 8.2 kW home solar system could produce about 14,400 kWh per year, based on the article’s NREL PVWatts estimate of 17,551 kWh annually for a 10 kW system.
Actual output varies with roof direction and condition, shading, dust, and seasonal sun and weather. Production is not even year-round: the article estimates about 49 kWh per day for a 10 kW system in July and 38 kWh per day in December.
Mesa homeowners may qualify for Arizona’s Form 310 income-tax credit: 25% of eligible solar-device costs, up to $1,000. Qualifying equipment sales may receive favorable transaction privilege tax treatment, and qualifying on-site solar is excluded from added property valuation. Export credits depend on the utility and plan; eligible APS battery customers may earn seasonal rewards.
The federal 30% residential tax credit is no longer available for cash purchases after the 2025 law change. With a LightReach lease, Palmetto claims the commercial investment tax credit and says it passes the savings through in lower payments.
Yes. Mesa’s sunny climate supports solar panels, with Arizona averaging about 6.5 peak sun hours per day. Panels still produce electricity on cloudy days, but at a lower rate; monsoon clouds and dust can also reduce output.
Production varies by season. A 10-kW system is estimated to generate about 58 kWh per day in May and 38 kWh per day in December. Longer days help summer output, while intense heat can temper production.
