Arizona solar panels guide 2023

Updated April 14, 2023

Considering the fact that Arizona gets some of the most peak sun hours in the country, installing solar panels seems like a no-brainer. 

But it’s not all about the sunshine. Some recent policy changes and the reeling back of incentives have caused a hiccup or two for the state’s solar industry, but it has thankfully persevered. Regardless of any changes, Arizona homeowners have great choices to make the most of their solar investment.

Solar power prices, savings and payback in your part of Arizona

The average cost for an installed residential solar system in Arizona is currently $11,071 after claiming the 30% federal solar tax credit. This is $2.64 per watt. However, there is some variance in solar prices in different parts of the state. The graph below shows the average cost of installed solar systems in your part of the state.

Are solar panels worth it in Arizona

Solar panels have fallen in price by more than 80% in the last ten years. In 2022 they also remain subsidized by the 30% federal tax credit and the net metering law, making them an excellent investment. They offer a return well above the long term average return from both the share market and also property investment.

Another way to look at this question is the levelized amount you will pay for each kWh of power you will use over the next 25 years with and without solar panels. As you can see below the savings are significant.

Arizona solar incentives & tax credits

Federal solar tax credit

The most significant incentive to install solar panels for homes and businesses in Arizona is the federal solar tax credit. Right now, you can get a tax credit equal to 30% of the total costs of your solar installation. Battery storage systems also qualify for the tax credit. 

The 30% tax credit is available until the end of 2032. In 2033, the tax credit value will fall to 26% of installation costs. Solar panels installed in 2034 will receive a tax credit equal to 22% of the solar system price before the incentive expires entirely in 2035. 

Arizona solar energy tax credit 

Not only do Arizona residents get to take advantage of the federal tax credit, but they can also receive the state’s solar energy credit. Arizona’s solar energy credit is equal to 25% of the costs of a solar system, up to $1,000. That is a significant amount of savings on your income taxes. 

Arizona net billing

Arizona replaced full retail net metering with net billing in 2016. Net billing is similar to net metering, except that excess energy produced by a solar system is credited at a lower rate than what you pay for electricity. 

So, if your system produces more electricity than you use, you will still be compensated for that excess generation; it will just be less than the retail rate. The exact rate varies from utility to utility.

Arizona sales tax exemption

The solar equipment sales tax exemption prevents the state’s sales and uses tax from being applied to solar energy equipment. It also prevents sales tax from being tacked onto renewable energy credits (RECs). The sales tax rate in Arizona is 5.6%, so this exemption saves you from having to spend a considerable amount of money. 

Property tax exemption

Typically, installing a solar system on your property would increase property taxes. However, thanks to Arizona’s Energy Equipment Property Tax Exemption, solar systems add no value to your property regarding property tax assessments.

Is it better to lease or buy solar panels in Arizona

You will save most money by buying your solar system rather than leasing it. Read more about the pros and cons of leasing vs buying solar.

How long do solar panels last?

Minimum of 25 years but generally 30 or more

How do solar panels work on a home?

Solar panels power your house when they can but your home uses the utility company for power at other times. In 2023 "solar systems with battery storage" are becoming more popular. These are known as hybrid systems.

How do solar panels work?

Grid-tied solar system

A grid-tied system is the most common type of solar system. It has no solar battery for backup power and utilizes net metering to maximize savings. Solar panels are mounted on your roof then wired together, and the power generated flows into an inverter where direct current (DC) electricity is converted into alternating current (AC) electricity. This electricity is either used by your home or is exported to the utility grid.

Hybrid solar system

In hybrid solar systems, rooftop solar panels are connected to both a solar battery and the electric grid. The solar electricity generated by your panels that your home does not use is stored in the battery instead of being sent to the grid, which reduces your reliance on the utility while also providing backup power when needed. Battery storage is still expensive but you may be able to reduce costs by using state incentives.

Off-grid solar system

Off-grid solar systems are not connected to the grid at all, so all of your energy needs must be met by the sun. There is no utility to fall back on. The solar installation needs to power your home not only during the day, but after dark as well, so many solar panels and a large battery system are required. These systems are often expensive and don’t make sense for homes that have access to the grid.

Do solar panels require regular maintenance?

No, but cleaning them can improve power generation if they are dirty.

Will residential solar power system cost fall in Arizona in 2023?

Given this environment, and the effect of import tariffs placed on solar panels by the Trump administration during 2018, it is hard to see that solar power system prices in Arizona will fall during 2023.

How much electricity do solar panel systems generate in Arizona?

Depending on the location, solar panels will generate different amounts of electricity.

A solar system that is installed on a south-facing 23.5-degree pitch roof Arizona will generate 1,752kWh of peak DC (direct current) capacity per year per 1kW in the Phoenix area.

What are the pros and cons of installing solar panels in Arizona?

What's great about going solar in Arizona is that you can take advantage of both the federal and the state tax credits. In addition to these incentives, Arizona receives the most sun in the U.S., so you don't need to buy as many panels to wipe out your electricity bill.

Unfortunately, though, utilities in the state don't offer full retail net metering, so savings are a bit lower than you might see in other states. It's not all bad, though; despite the three major utilities in Arizona buying excess solar energy for a lower rate, it's not too much lower than the retail cost of electricity. But, over time, the generation credit rate will get lower, so consider going solar sooner rather than later to get the most value out of your solar energy.
