When Is the Best Time to Go Solar in Arizona?

Arizona gets more sunshine than almost any other state in the country. If you own a home here, you've probably wondered whether switching to solar makes sense — and when the timing is right. The short answer: sooner is usually better, but there are specific windows that can save you even more money. Here's what you need to know.

Why Arizona Is One of the Best States for Solar

Arizona averages around 300 sunny days per year. That kind of sun exposure means solar panels produce electricity at or near peak capacity for a larger portion of the year compared to states in the Northwest or Midwest. Phoenix, Tucson, Scottsdale, and surrounding areas sit in what solar experts call a "high solar resource" zone.

Beyond weather, Arizona has a policy environment that supports residential solar. The state offers a personal income tax credit equal to 25% of the cost of a solar system, up to $1,000. That stacks on top of the federal solar Investment Tax Credit (ITC), which is currently set at 30% of installation costs for systems placed in service through 2032 (confirm current ITC rate with your installer or a tax professional, as federal policy can change).

The Best Season to Install Solar Panels in Arizona

There's no single "wrong" month to go solar in Arizona, but fall and winter (October through February) tend to be the smartest time to schedule your installation for a few reasons:

1. Faster installation timelines. Spring and summer are peak season for solar installers. Demand surges as homeowners see their summer electric bills spike. Scheduling in the off-season often means shorter wait times — sometimes weeks shorter.

2. Panels are up before peak demand. If you install in October or November, your system is permitted, connected, and running before the brutal Arizona summer hits. You'll be generating your own power right when APS, SRP, or TEP rates are highest.

3. Potential for better pricing. Some installers offer off-season promotions or have more flexibility to negotiate when their schedule isn't packed. It never hurts to ask.

That said, if you install in the summer, you'll still benefit — you'll just miss part of the high-production season while waiting for permits and connection approvals.

How Arizona Net Metering Affects Your Timing Decision

Net metering is the policy that lets you sell excess electricity back to the grid. Arizona's net metering rules have evolved in recent years. The Arizona Corporation Commission (ACC) has made adjustments to how utilities credit solar customers for exported power, and the specifics vary by utility (APS, SRP, TEP, etc.).

This matters for timing because the sooner you get connected, the sooner you lock in your current rate structure. If you're on the fence, waiting could mean installing under a less favorable export credit arrangement in the future. Policies can shift — confirm the current net metering terms with your utility and a licensed installer before signing a contract.

What Incentives Should Arizona Homeowners Know About?

Here's a quick summary of incentives worth exploring:

Federal ITC (30%): Reduces your federal income tax liability by 30% of the total system cost. This applies to equipment and installation labor.
Arizona State Tax Credit (25%, up to $1,000): Applied to your state income tax. Note that you cannot claim this credit on costs already covered by the federal credit — confirm with a tax professional.
APS/SRP Rebates: Some utilities have offered rebates in the past, but availability changes. Check directly with your utility for current programs.
Property Tax Exemption: Arizona exempts the added value of a solar system from residential property taxes. Your property value goes up; your property tax bill doesn't.
Sales Tax Exemption: Arizona exempts the purchase of solar energy equipment from state sales tax.

These incentives can significantly reduce your out-of-pocket cost. A qualified installer can walk you through exactly what you'd qualify for based on your system size and tax situation.

How to Choose the Right Solar Installer in Arizona

Not all installers are equal. Before you sign anything, ask these questions:

Are you licensed in Arizona and NABCEP certified?
What brands of panels and inverters do you install?
Who handles permitting and utility interconnection?
What does the warranty cover, and who backs it?
Do you offer financing, lease, or PPA options — and what are the long-term trade-offs?

Get at least two or three quotes. Prices for residential solar in Arizona vary widely depending on system size, equipment quality, and installer overhead. Connect with pre-screened Arizona solar installers here to compare options without the pressure.

FAQ

How long does it take to install solar in Arizona?

Once you sign a contract, most residential installations take 1 to 3 months from start to finish when you factor in permitting, utility approval, and inspection. Installing in the off-season (fall/winter) can shorten that timeline.

Does Arizona have a solar mandate or requirement?

No. Going solar is entirely voluntary for homeowners. However, Arizona does have renewable energy standards for utilities, which is one reason programs supporting residential solar have remained available.

Is solar worth it in Arizona even if I have an HOA?

Generally yes. Arizona law (A.R.S. § 33-1816) prohibits HOAs from unreasonably restricting solar panel installations. Your HOA may have guidelines about placement and aesthetics, but they cannot outright ban solar on your home.

What if I rent — can I still go solar?

Renters typically cannot install panels on a property they don't own. However, some utilities and community solar programs allow renters to subscribe to shared solar capacity and receive bill credits. Ask your utility about community solar options.

Does solar increase my home's value in Arizona?

Research consistently shows solar installations increase home resale value. Because Arizona's property tax exemption excludes the added solar value, you get the benefit without a higher tax bill.
