What Incentives and Tax Credits Are Available for Solar Energy Systems

Going solar is one of the most impactful home upgrades you can make for your wallet and the environment. With the right incentives and tax credits, solar energy systems become even more affordable, providing savings that can significantly reduce installation costs and boost your return on investment.

At Sundial Home Services, we help Arizona homeowners take full advantage of available incentives and tax credits when switching to solar energy. In this guide, you’ll learn exactly what savings are available, how they work, and how you can claim them when you install solar panels and battery systems with us.

Why Solar Incentives and Tax Credits Matter

Solar energy systems are a long-term investment with benefits that extend far beyond reducing your electric bill. However, the upfront cost can still be a barrier for many homeowners. That’s where government incentives and tax credits come in — by lowering your net costs, these financial supports make solar more accessible and economically attractive.

Incentives come at the federal, state, and local levels, and they can include:

• Tax credits that reduce the amount you owe at tax time

• State rebates or credits that lower your overall system cost

• Exemptions from sales or property taxes

• Performance-based payments

• Net metering credits on your utility bill

Understanding what’s available can dramatically improve your solar return on investment.

The Federal Solar Tax Credit (Residential Clean Energy Credit)

One of the most powerful financial incentives for solar has historically been the federal solar tax credit, also known as the Solar Investment Tax Credit (ITC).

What It Is

• The federal tax credit allows homeowners to claim a percentage of their solar system cost as a credit against federal income tax.

• Traditionally, this credit has been 30% of the total cost, including equipment and labor, and it has applied to solar panels, solar batteries, and related equipment.

How It Works

• After installing your solar energy system, you claim the credit when you file your federal tax return (IRS Form 5695).

• The credit directly reduces the amount of federal tax you owe — dollar-for-dollar. For example, if your solar installation costs $25,000, a 30% credit would be worth $7,500.

• If you don’t owe enough taxes in the first year to use the full credit, you may be able to carry the unused portion forward to future tax years (subject to current IRS guidelines).

Important Deadline Considerations

Recent legislation has brought changes to the federal solar tax credit timeline. As of 2025, the 30% credit for residential solar may be expiring or scaling down, making it more critical than ever to complete your solar project sooner rather than later to capture the full benefit.

Note: Eligibility, application, and credit amounts may change over time. Always consult your tax professional or a certified solar consultant to understand current federal rules.

Arizona State Solar Incentives and Tax Credits

Arizona is one of the most solar-friendly states in the U.S., thanks not just to its abundant sunshine but also to state-level incentives that complement federal benefits.

Arizona Residential Solar Tax Credit

Arizona offers a state tax credit for homeowners who install solar energy systems on their property.

Key features include:

• 25% credit of your solar system cost

• Up to $1,000 maximum credit

• Unused credits may be carried forward for several years if your state tax liability isn’t large enough in the first year.

This credit is especially valuable because most states do not offer any solar tax credits at all. When combined with federal incentives, Arizona’s credit can make a significant dent in your net cost.

Sales and Property Tax Exemptions

In addition to the tax credit:

• Arizona often exempts solar equipment from state sales tax, meaning you don’t pay sales tax on the purchase price of your solar system.

• Some local jurisdictions may also offer property tax exemptions, so your home’s assessed value doesn’t increase just because of a solar installation.

These exemptions ensure that installing solar doesn’t trigger higher property taxes or unexpected fees.

Other Solar Incentives to Know About

Beyond the primary federal and state tax credits, there are additional incentives available in some regions that can amplify your savings.

Utility Rebates

Many utilities across Arizona and nationwide offer rebates or performance-based incentives to encourage solar adoption. These funds are distributed based on the size of your system or the amount of energy it produces.

Examples include:

• Net metering credits that allow you to earn bill credits for excess energy you export to the grid

• Performance payments for systems that meet production goals

• Time-of-use incentives that reward energy exports during peak demand

These programs vary by utility company and region, but they can stack with tax credits to create even stronger financial returns.

Local and County Solar Programs

Some cities or counties offer additional incentives, such as:

• Rebates on solar installations

• Low-interest loans or financing support

• Community solar partnership programs

These programs are less common but worth exploring with your solar provider or local energy office.

How Solar Incentives Translate into Real Savings

Let’s break down a realistic example of how tax credits and incentives can impact your cost:

Sample Solar System Cost Breakdown

Cost ComponentEstimated AmountSolar Panels, Inverter, and Equipment$20,000Installation and Labor$5,000Total System Cost$25,000

Federal Solar Tax Credit (30%)
Credit applied on federal taxes: $25,000 x 30% = $7,500 tax credit

Arizona State Solar Tax Credit (25%, max $1,000)
State tax credit: $1,000

Net Installation Cost After Credits
$25,000 – $7,500 – $1,000 = $16,500

Depending on rebates, utility incentives, and net metering benefits, your effective cost could be even lower.

Frequently Asked Questions

Q: Do tax credits require me to own my solar system?
A: Yes. Tax credits like the federal ITC typically require you to purchase and own the solar system outright. Lease and power purchase agreement (PPA) arrangements may not qualify for some credits.

Q: Can I carry unused credits forward?
A: In many cases, yes — especially for state tax credits like Arizona’s. Federal carryforward rules can vary, so consult your tax preparer.

Q: What happens if I claim solar incentives but sell my house?
A: Incentive rules vary. Some credits may be transferable, while others may require repayment. A tax professional can help you plan around home sales.

Q: How soon should I install to qualify for incentives?
A: The earlier the better. Federal incentives may be changing, so completing your system while current incentives are active can maximize your savings.
