- APS and SRP have different rates and solar rules, so check your utility plan and eligible Arizona incentives when estimating savings.
Glendale Electricity Prices
Electricity costs shape household budgets in Glendale, especially during long, hot summers when air conditioning can drive energy use.
The chart shows Arizona’s average electricity price rose from 12.5¢ per kWh in 2021 to 14.9¢ in 2024. The national average increased from 13.7¢ to 16.5¢. These are statewide and national figures, not Glendale-specific rates.
For Glendale homes, solar panels can generate power during sunny daytime hours, potentially reducing electricity bought from the grid when cooling systems are working hardest. The impact depends on the home, system, utility plan, and when electricity is used.
Over time, solar generation may help households offset grid purchases and manage exposure to changing electricity prices. Long-term value varies with system output, utility rates, fees, and maintenance, so savings are not guaranteed.
Price of Energy: Arizona vs National Average
Glendale Area Utility Providers
Glendale residents may receive electricity from APS or SRP. In 2023, APS averaged 15.3¢ per kilowatt-hour and SRP 12.5¢, compared with Arizona’s 14.0¢ and the national average of 16.0¢.
These 2023 figures place APS above the state average but below the national average. SRP’s rate was below both. The comparisons show different rates among Glendale-area providers, but do not explain what caused those differences.
For Glendale households considering solar, electricity rates help frame the potential value: using solar power at home may reduce the amount of electricity purchased from a utility. Actual savings depend on household use and the utility’s rules.

Arizona Solar Incentives
Glendale homeowners may find state and local incentives that help offset solar installation costs. Review the solar incentives in Arizona below.
Options include an Arizona income-tax credit, qualifying sales-tax and property-valuation treatment, utility-specific export compensation, and battery rewards through APS or TEP programs.
Incentives vary by eligibility and utility. With LightReach leasing, Palmetto handles the commercial ITC and passes savings through lower monthly payments, simplifying the incentive process.
| 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.
Check the current terms, rates, interconnection requirements, and enrollment status directly with your utility: APS renewable riders.
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 Glendale
Verify the license
Paid residential solar installation generally requires an appropriate Arizona contractor license. Solar-device installers must meet the qualifications that apply to solar work, and the right license classification depends on the project’s scope. Ask each installer for its legal business name and Arizona license number, then verify the license and classification directly with the Arizona Registrar of Contractors (AZ ROC). Make sure the licensed contractor—not just a salesperson or subcontractor—is responsible for the work. If you cannot confirm the details, check with the AZ ROC before signing.
Look for certified installers
Ask whether the people designing and installing your system hold relevant certifications, such as a credential from the North American Board of Certified Energy Practitioners (NABCEP). You can learn about NABCEP at nabcep.org. Also ask whether the installer has manufacturer certifications for the proposed panels or inverters. These credentials can indicate training or product-specific qualifications, but they do not replace an Arizona contractor license or guarantee a particular result. Ask who on your project holds each credential and what it covers.
Compare quotes the same way
Request written proposals with comparable assumptions. Check that each quote clearly states:
- System size: capacity in kilowatts (kW), along with the proposed panel and inverter brands and models.
- Price: total system price and price per watt, calculated consistently across quotes.
- Production: estimated annual electricity production in kilowatt-hours (kWh/year) and the assumptions behind the estimate.
- Warranties: panel product and performance coverage, inverter coverage, workmanship, and roof penetrations. Ask who handles a claim.
- Responsibilities: who obtains permits, schedules inspections, and handles the utility interconnection application and agreement.
- Payment: total cost or monthly payment, financing or lease terms, and any payment escalator. Compare the full terms, not just the starting payment.
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 the property address. The homeowner or installer applies to the serving electric utility for interconnection and an agreement. Across Arizona, providers include Arizona Public Service Co, Salt River Project, Tucson Electric Power Co, and UNS Electric, Inc. Confirm which serves your address. ACC-jurisdiction utilities require an interconnection agreement before connection; municipal electric systems may have different requirements.
Arizona law limits HOA and covenant restrictions on rooftop solar: planned-community associations cannot prohibit solar devices, and placement rules must not prevent installation or impair function, use, cost, or efficiency. Covenants that effectively prohibit solar are generally void, subject to an exception for instruments entered into before April 17, 1980. These protections do not create an easement over neighboring property. See A.R.S. §§ 33-1816 and 33-439.
Red flags
- Pressure to sign the same day or claims that an offer will disappear before you can review it.
- Unlicensed crews, or out-of-state crews whose Arizona license and responsible contractor you cannot verify.
- Vague production estimates, or a refusal to explain the assumptions behind them.
- A large upfront deposit without clear written terms for what it covers and when work begins.
- Promises of federal tax credits for homeowner purchases made in 2026; homeowner credits ended December 31, 2025.
Palmetto is one installer you can include in your comparison, with a lease option through LightReach.
Leasing Solar Panels
In Glendale, Palmetto offers solar leasing for eligible homes served by Arizona Public Service Electric (APS) and Salt River Project (SRP). A lease typically has a set monthly payment; a power purchase agreement (PPA), which is not listed as available here, charges for the electricity the system generates. Learn more about buying or leasing solar.
With a PPA, payments can vary by season as solar production changes. Lease payments are generally fixed, which can make monthly costs more predictable.
Leasing avoids paying the full system cost upfront. With Palmetto’s LightReach lease, Palmetto owns and maintains the system, so you don’t have to manage routine system maintenance yourself. Review LightReach details and contract terms to understand what’s covered.
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!

Glendale, AZ has solar export credits, but most customers do not receive traditional 1:1 net metering. The credit rules depend on your electric utility. Glendale residents are commonly served by APS or SRP.
APS credits exported energy at its set export rate, currently listed as $0.06857 per kWh, while SRP’s credit varies by season and eligible time-of-use plan (about $0.02–$0.06 per kWh). Check your utility’s current tariff for exact rates and terms.
Yes. A purchased, homeowner-owned solar system may increase a Glendale home’s resale value. Zillow’s study found homes with solar panels sold for about 4.1% more on average, though the premium is not guaranteed for every home.
This finding applies to owned systems, not leased or third-party-owned (TPO) systems. A buyer may need to assume a lease agreement, which can affect resale differently. Arizona’s exclusion of qualifying solar equipment from assessed property value for tax purposes is separate from market value.
In Glendale, a LightReach solar lease has no upfront cost and a low fixed monthly payment. The calculator estimates $77 per month for a smaller home, $105 for a medium home, and $142 for a larger home.
Cash purchase is another option: estimated costs after the listed $1,000 Arizona incentive range from $16,824 to $29,726 ($22,405 for a medium home). The federal 30% tax credit is no longer available for residential cash purchases following the 2025 law change. See the calculator above for specific pricing.
With Palmetto’s LightReach lease, Palmetto owns the panels; homeowners pay monthly instead of buying the system. In Glendale, an 8.20 kW system is estimated at $105/month, using Arizona’s 1,624 kWh/kW/year production ratio and $0.095/kWh rate.
No upfront cost: one payment covers panels, installation, monitoring, maintenance, comprehensive protection, and a 90% Production Guarantee. The lease payment is typically below the current electricity bill, so savings may begin right away, though utility charges may remain.
A typical 8.2-kW home solar system in Glendale could produce roughly 14,500 kWh per year. The article’s NREL PVWatts estimate is 17,655 kWh annually for a 10-kW system, which scales to about 14,500 kWh for an 8.2-kW system.
Actual production varies with roof direction and pitch, shading, dust, equipment, and seasonal conditions. Glendale’s summer heat and monsoon clouds can also affect output.
Solar panels are low maintenance in Glendale. Dust can build up in Arizona’s dry climate, so occasional cleaning may help keep panels clear; monitoring can also reveal changes in system output.
With LightReach, Palmetto owns the system and handles maintenance, monitoring, and repairs at no extra cost. The plan also includes a 90% Production Guarantee.
Yes. Glendale’s abundant sunshine supports solar panels, with Arizona averaging about 6.5 peak sun hours per day. NREL-based estimates in the article show a 10-kW system producing about 58.3 kWh per day in May and 35.4 kWh per day in December.
Panels also generate electricity on cloudy days using available daylight, though output drops. Glendale’s summer heat, monsoon clouds, dust, and shorter winter days can affect production, so solar output varies by season and weather.
