Is Solar Worth It in Arizona in 2026?

Is solar worth it in Arizona? At first glance, Arizona seems like the easiest solar decision in America.

There is abundant sunshine.

Air conditioners work hard for months at a time.

Many homes use substantial amounts of electricity.

So solar must automatically make sense, right?

Not necessarily.

Arizona has excellent solar resources, but the economics can vary considerably depending on:

• Your utility
• Your electric rate plan
• How much solar electricity you use inside the home
• How much you export
• Your air-conditioning efficiency
• Roof orientation and shading
• System price
• Financing

That's why the better question isn't:

It obviously does get enough sunshine.

Arizona Has Excellent Solar Potential

Few states have a more intuitive solar case than Arizona.

A well-positioned rooftop can receive substantial sunlight throughout the year.

That means solar may be particularly attractive for homes with:

• Significant electricity consumption
• Strong roof exposure
• Limited shade
• A newer roof
• High daytime usage
• Long-term homeownership plans
• Efficient HVAC equipment

But great sunshine doesn't rescue poor project economics.

A solar system still needs to be correctly sized and correctly priced.

Your Utility Matters More Than You May Think

Arizona homeowners should not assume that every utility treats residential solar the same way.

Two particularly important utilities are:

• Arizona Public Service, or APS
• Salt River Project, or SRP

Their residential solar structures differ.

That means a homeowner in Phoenix can have different solar economics than another homeowner a relatively short distance away.

Before comparing solar proposals, identify your utility.

How Does APS Treat Excess Solar?

APS uses what it calls renewable-energy riders.

Its current Resource Comparison Proxy, or RCP, operates as a net-billing arrangement (a set dollar credit for solar power you send to the grid).

Sometimes your solar system makes more electricity than your home is using. That extra power is exported to the grid, and APS applies a dollar credit based on the applicable RCP purchase rate. Unused credits can roll forward, and qualifying remaining balances can ultimately be refunded.

That is different from traditional one-for-one net metering.

The electricity you avoid purchasing may have a different value than the electricity you export.

That's an important distinction.

Why Solar Self-Consumption Matters

Suppose your solar panels generate 1 kWh (kilowatt-hour, the unit on your bill).

Those two kilowatt-hours can have different economic value.

That means Arizona solar design should consider when the household uses power, not only total annual consumption.

SRP Is Different

Salt River Project has its own residential solar rate plans.

SRP customers with onsite generation choose from price plans specifically designed for customers who produce electricity.

Some plans incorporate time-of-use pricing and export compensation.

For example, SRP currently offers an Electric Vehicle Export Price Plan for qualifying solar customers with an EV, with rates that vary by time period. SRP also announced a temporary reduction in certain energy prices for the May through October 2026 billing cycles.

The broader lesson is simple:

Utility territory and rate plan matter.

Arizona Still Has a State Residential Solar Tax Credit

Arizona law provides a residential solar-energy credit equal to 25% of the qualifying cost up to a maximum credit of $1,000.

The credit is nonrefundable, and unused qualifying credit can generally be carried forward for up to five years.

That's a useful benefit.

But it is much smaller than the former federal residential credit.

What Happened to the Federal 30% Solar Tax Credit?

The former federal Residential Clean Energy Credit ended for new residential clean-energy property after December 31, 2025.

The 30% credit applied to qualifying systems installed from 2022 through the end of 2025. It is not available for property placed in service after that date.

That means a 2026 Arizona proposal should not automatically show:

“Federal tax credit: 30%.”

For a new project, the homeowner should evaluate:

• Arizona's state credit
• Utility export value
• Electricity savings
• Actual system cost
• Financing
• Roof condition
• Expected ownership period

Why HVAC Matters So Much in Arizona

This is where Ashborn's whole-home approach becomes particularly relevant.

Arizona homeowners can have enormous summer cooling loads.

A high electric bill may partly be caused by:

• An aging AC system
• Multiple inefficient systems
• Leaky ductwork
• Poor attic insulation
• Air leakage
• An oversized or poorly performing unit

Solar can generate electricity to support that load.

But it does not reduce the load itself.

Should You Replace Your AC Before Installing Solar?

Sometimes.

Imagine your current house uses 22,000 kWh per year.

A solar company could design a system around that usage.

But if an HVAC replacement and efficiency improvements reduce annual consumption to 17,000 kWh, the solar system required afterward may be significantly smaller.

That can mean:

• Lower project cost
• Fewer panels
• Less financing
• Less exported electricity
• Better alignment with household consumption

Sometimes the right strategy is:

When Solar Should Come First

Consider a different Arizona home.

It has:

• A modern high-efficiency HVAC system
• Good insulation
• Strong roof exposure
• Limited shade
• High legitimate household electricity use
• A newer roof

There may not be much inefficient consumption left to remove.

Solar may then deserve priority.

The question becomes:

What About Battery Storage?

Battery storage can be particularly interesting in Arizona for two reasons.

First, a battery can store solar production for use later when the home is consuming more electricity.

Second, a properly configured battery system can provide backup power during an outage.

That can matter when extreme temperatures make loss of cooling more than a minor inconvenience.

Can a Battery Help With Export Economics?

Potentially.

Exported electricity may be worth less than the electricity you buy from the utility later. If so, you may prefer to store some excess solar production for use inside the house.

But batteries are expensive.

The calculation needs to compare:

• Battery cost
• Solar export value
• Retail electricity rates
• Time-of-use rates
• Household usage pattern
• Backup-power value

A battery should solve a real problem — not simply make a solar proposal look more technologically complete.

Solar Panels Alone Generally Aren't Backup Power

A typical grid-connected solar system is designed to shut down during a utility outage.

That helps protect workers repairing utility lines.

To operate when the grid goes down, the home needs equipment specifically designed for backup operation.

Battery storage is commonly part of that design.

So homeowners concerned about outages should ask:

• What stays powered?
• Can the AC operate?
• How many battery units are required?
• How long can they support the desired loads?
• Can solar recharge the batteries while the grid remains down?

Can You Back Up an Arizona Air Conditioner With Batteries?

Potentially, but air conditioning is a substantial electrical load.

There is a huge difference between backing up refrigerator, lights, internet and a few outlets — and a large central air-conditioning unit.

Whole-home backup may require significant battery capacity and inverter output.

That can materially increase cost.

The backup design should start with the loads you actually need.

So, Is Solar Worth It in Arizona?

For many homeowners, yes.

Arizona offers:

• Excellent solar production potential
• A state residential solar tax credit
• Large household cooling loads
• Multiple utility solar programs
• Potential solar-plus-storage opportunities

But the smartest home-energy investment still depends on the house.
