Arizona Solar Panels

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 and TEP describe 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, TEP RCP, 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.

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.

SRP pays participating customers $55 per average kW, with bill credits issued twice a year based on battery performance during demand events. Customers may be notified of events and can opt out under the program rules.

Enrollment requires SRP residential service and a battery through a participating partner. SRP states the pilot is limited to 5,000 customers and is approved through April 30, 2030, so availability may be limited. Review current partner, eligibility, and enrollment requirements at SRP Battery Partner.

SRP pays eligible customers $0.005 (one-half cent) for each kWh generated by their solar system, issued as monthly bill credits. The payment is based on system generation and is separate from any export compensation under the customer’s SRP price plan.

The customer must be an SRP residential customer and own the renewable energy certificate rights associated with the system. A lease or prior agreement assigning REC rights to another party can make the customer ineligible, and some solar-plus-battery configurations may not qualify. Check program details and eligibility with SRP’s REC Purchase Program.

Mohave Electric Cooperative (MEC) lists a rebate of $0.05 per watt for qualifying solar or wind systems, up to $2,500, for eligible residential and small-commercial systems no larger than 50 kW. The program is for MEC members, and leased systems are not eligible for the rebate.

Submit the reservation or application before work begins. Funding may be limited; MEC indicates applicants may be waitlisted if funds are unavailable, so confirm availability and requirements before signing a contract or starting installation. See MEC SunWatts program information.

MEC’s Mohave Charged program offers a $500 rebate per qualifying battery installation to eligible residential and commercial members. The battery must have at least 5 kWh of usable capacity and programmable controls and/or Wi-Fi, and it must not charge during on-peak periods.

MEC states that the battery must have been purchased and installed after January 9, 2022. The application requires installation receipts and approved permits. Confirm current funding, deadlines, and documentation requirements with MEC Mohave Charged.
