What Are Arizona Solar Export Credits Worth in 2026?
Arizona solar export credits in 2026 pay far less than most homeowners expect. Under the state's net billing rules, APS credits excess solar at the Avoided Cost Rate, currently around 3.2 cents per kilowatt-hour. SRP's export credit sits near 3.0 cents per kilowatt-hour. Both figures represent what each utility would have paid to generate that power elsewhere, not what they sell it back to you for.
The gap is what matters. That same kilowatt-hour you export for 3 cents costs you roughly 14 cents when you pull it back from the grid after sunset. Multiplied across a typical Phoenix summer, the difference runs into hundreds of dollars a year. Homeowners who treat export volume as the measure of solar performance often end up surprised when the annual true-up bill arrives and the math does not match the sales pitch.
The better frame is self-consumption rate: how much of your solar power you actually use inside your home. Maximizing that number, rather than chasing higher export totals, is what separates a good solar investment from a mediocre one.

How Does APS Net Billing Work for Arizona Solar Customers?
APS net billing credits your solar exports at the Avoided Cost Rate (ACR), a figure the Arizona Corporation Commission reviews periodically based on wholesale power market conditions. For 2026, the ACR sits near 3.2 cents per kilowatt-hour. Credits accumulate monthly and appear on your bill, but they do not roll over as cash. Unused credits at the end of your annual true-up period are forfeited.
The timing math is worth running once so it sticks. A system that generates 20 kilowatt-hours on a peak Phoenix day but pushes 15 of those back to the grid because nobody is home earns about 48 cents in credits on those 15 kilowatt-hours. The same 15 kilowatt-hours used at home would have offset around $2.10 in grid purchases. Self-consumption is worth roughly four times as much as exporting under the current rate structure.
APS offers several time-of-use plans for solar customers, including the E-12 Solar plan, which pairs a demand charge with lower energy rates. The choice of rate plan interacts directly with how you manage household loads, so reviewing APS solar rate plans before finalizing your system design is worth doing.
What Does SRP Pay for Solar Exports in 2026?
SRP's export credit for residential solar customers sits near 3.0 cents per kilowatt-hour in 2026, comparable to APS's avoided cost rate. SRP calculates its export credit using a similar avoided cost methodology, and the figure adjusts as the utility updates its cost filings.
One practical difference: SRP's standard rate plans include a monthly demand charge based on your single highest-draw hour during the billing period. That structure can hit a household hard if it pulls heavy grid loads during one late-afternoon hour, even if solar covers most of the month. Understanding your utility's specific pricing mechanics, which depends on your neighborhood address rather than your city, is the starting point for any useful solar analysis.
For a direct comparison of how the two utilities handle solar export economics, the APS vs SRP solar export rates post covers the key rate plan differences in detail.
Three Levers to Maximize Arizona Solar Export Credits in 2026
Getting more from your arizona solar export credits in 2026 does not mean exporting more power. It means reducing how much low-value power you send to the grid in the first place. Three levers drive the biggest improvements: shifting loads to solar production hours, adding battery storage to capture peak-window value, and right-sizing the system to match actual consumption.
Can Load Shifting Really Change What You Save on Solar in Arizona?
Yes, and it is the lowest-cost lever available. Moving high-draw appliances to the 10 a.m. to 2 p.m. window in Phoenix means your solar system powers them directly. You consume a kilowatt-hour at roughly 14 cents of offset value instead of exporting it at 3.2 cents. Dishwashers, washing machines, clothes dryers, pool pumps, and EV chargers are the primary targets.
A typical Phoenix home running a pool pump for four hours and a dishwasher cycle between 11 a.m. and 2 p.m. can shift four to six kilowatt-hours per day from export to self-consumption. Over a full Arizona summer, that shift can add $200 to $350 per year in bill savings compared to running those same loads in the evening. A programmable timer or smart home controller handles the scheduling automatically once configured, with no new solar hardware required.

Does Adding Battery Storage Improve Solar Savings in Arizona?
Battery storage is the most powerful lever, and it works differently than most homeowners assume. The value is not about getting paid more for exports at peak time. It is about capturing midday solar that would otherwise go to the grid at 3.2 cents and using that stored power at home during the 4 to 8 p.m. window when grid electricity costs 14 cents or more per kilowatt-hour.
A 10 kilowatt-hour battery paired with a solar system can store a full day's surplus and discharge it through the evening peak. The daily bill savings across a Phoenix summer can reach $1.50 to $2.50 per cycle, adding up to several hundred dollars annually before accounting for backup power during outages. For Arizona homeowners, the value of battery storage is primarily a self-consumption story, not a grid-export story.
The Arizona home battery comparison covers how the Tesla Powerwall 3, Enphase IQ 10C, and Franklin aPower 2 perform in sustained Arizona heat, which is a more demanding environment than most battery spec sheets account for.
How Does System Size Affect Your Arizona Solar Export Credits?
An oversized system exports more, but more exports at 3.2 cents is not more savings. The right system size for most Phoenix homes matches annual production to annual consumption within a range of 90 to 110 percent. That leaves room for normal weather variation and household demand shifts without pushing large amounts of power to the grid at low-value rates.
Phoenix averages 5.8 peak sun hours per day, which makes system sizing calculable with real precision. A home consuming 900 kilowatt-hours per month needs approximately 7 to 8 kilowatts of panels to reach that target range under Phoenix conditions. Going significantly larger just to see a higher production number increases upfront cost without a proportional return on the additional kilowatt-hours.

How Solar Export Strategy Plays Out Across the Phoenix Valley
What Phoenix and Scottsdale Homeowners Should Know
In core Phoenix and Scottsdale, many neighborhoods fall under APS service territory, though utility assignment depends on your specific street address rather than your city. APS customers on time-of-use plans have a clear financial incentive to keep heavy loads off the evening hours and to self-consume as much solar as possible during production hours. The combination of load shifting and battery storage can close most of the gap left by the low avoided cost rate, making the total savings from solar panels lower your electric bill more meaningfully than export credits alone ever would.
What Mesa, Chandler, and Gilbert Homeowners Should Know
Mesa, Chandler, and Gilbert each contain neighborhoods under SRP service territory, though again the utility depends on the specific address. SRP's demand charge structure makes a single high-draw appliance running in the late afternoon a significant bill event, even if solar covers most of the month's energy use. Careful load management matters as much as system size for SRP customers who want to reduce their electric bill in Arizona and keep export value working in their favor.
What Tempe and Peoria Homeowners Should Know
Tempe and Peoria both contain neighborhoods served by each utility. Residents need to confirm their utility from a recent bill before designing a system. The export credit mechanics differ enough between APS and SRP that a system optimized for one utility's rate plan will not perform the same way under the other's. Any solar installer quoting your home without asking about your utility and current rate plan is skipping the most important input in the analysis.
How to Choose a Solar Installer in Phoenix for Export Optimization
The best solar company in Phoenix for a given homeowner is the one whose proposal actually accounts for that homeowner's utility, rate plan, and household load pattern. A proposal that shows total production and a payback period without breaking down projected self-consumption rate and annual export volume is leaving out the numbers you need to evaluate the real return.
Compare solar installers in Phoenix by asking each one to model both scenarios: with and without a battery, and with load shifting factored in versus not. That comparison surfaces which installer actually understands the local rate structure and which is running a generic calculation. Getting solar quotes in Phoenix from multiple installers simultaneously, through an independent broker rather than through each company's own sales channel, is the most efficient way to run that comparison.

The Financing Angle: Prepaid Lease vs Owned System in 2026
The federal residential solar tax credit under Section 25D expired after December 31, 2025, for homeowners who buy their system outright with cash or a loan. Purchasing in 2026 means no 30 percent federal credit to claim. That changes the upfront economics significantly for buyers who were counting on the credit.
A prepaid solar lease takes a different path. The leasing company can claim the 48E commercial clean energy credit through 2027 and pass that 30 percent savings to the homeowner as a lower upfront price. The result is the same 30 percent discount on day one, structured as a reduced lease prepayment rather than a tax credit filing. This arrangement is not tax advice; consult a tax professional about how it applies to your specific situation.
From an export optimization standpoint, a prepaid lease system is sized and configured the same way as an owned system. All three levers above apply equally regardless of ownership structure, so the export strategy does not change based on how you finance the panels. The prepaid solar lease vs loan comparison walks through how the total cost plays out over 25 years under each option for Arizona homeowners.
The bottom line for Phoenix homeowners evaluating residential solar in Arizona is this: export credits are a real but limited part of the return. The homeowners who get the most from their systems treat load management and self-consumption as primary goals and treat exports as the residual. That shift in framing, away from production maximization and toward consumption optimization, is what moves a solar investment from average to genuinely good.
Frequently Asked Questions
What does APS pay for solar exports in 2026?
APS credits excess solar at the Avoided Cost Rate, approximately 3.2 cents per kilowatt-hour in 2026. That is far below the retail rate of around 14 cents per kilowatt-hour, which is why self-consuming your solar production is worth roughly four times more than exporting it to the grid.
Does SRP pay more for solar exports than APS?
SRP's export credit sits near 3.0 cents per kilowatt-hour in 2026, similar to APS. Neither utility pays close to the retail rate for exported power, so shifting heavy loads to midday solar hours and adding battery storage will generate more bill savings than simply increasing export volume.
How does battery storage increase solar savings in Arizona?
A home battery stores excess midday solar instead of exporting it at about 3 cents per kilowatt-hour. You then use that stored power in the evening when grid electricity costs around 14 cents per kilowatt-hour, turning the difference into real bill savings every day throughout the Phoenix summer.
What is the best time to run appliances for maximum solar savings in Phoenix?
Run dishwashers, laundry, pool pumps, and EV chargers between 10 a.m. and 2 p.m. in Phoenix. That is when solar production peaks, and using power directly offsets 14 cents per kilowatt-hour of grid purchases rather than exporting it at 3 cents under APS or SRP net billing.
How to choose a solar installer in Phoenix for export optimization?
Ask each installer to show projected self-consumption rate and estimated annual exports alongside system size and price. Compare solar installers in Phoenix through an independent broker so you can see multiple proposals side by side without each company's sales pressure shaping what numbers you see.
Can I still get a 30 percent solar discount if I missed the 2025 federal tax credit?
Yes. The Section 25D residential credit expired after 2025 for owned systems, but a prepaid solar lease lets the leasing company claim the 48E commercial credit through 2027 and pass the 30 percent savings to you as a lower upfront price. This is not tax advice; consult a tax professional.
