We’ve talked to hundreds of Arizonans who have already gone through the solar panel installation process. Here’s what Glendale residents should look out for when choosing a solar panel installation company. We’ll also touch on overall costs and ways to save with local and federal incentives.

A typical solar panel installation costs anywhere from $7,560 to $21,600 in Arizona. Prices in Glendale are comparable, ranging from $7,637 to $21,821 on average.

Installers usually price systems according to their wattage. “Cost per watt” is like the “price per square foot” when you buy a house. It helps you compare the value of solar energy systems in different sizes. In Glendale, the average cost per watt is $2.18.

Average total solar installation costs by system size in Glendale

The average Arizona household needs a system with a capacity of 9.2 kW to fully offset their electricity costs. Depending on your household energy use, you might need a smaller or larger one.

Solar panels are generally worth it in Arizona if you like the idea of lowering your monthly utility bills. The main drawback is the high upfront cost of purchasing and installing the panels and equipment.

Living in Glendale, it’s hard not to run the air conditioning 24 hours a day most of the year. Like a lot of residents, Maria in Surprise went solar not only for the environmental benefits but also to stop worrying about how much electricity she uses, especially in the summer.

Homeowners with solar panels typically save $20,000 to $90,000 over 25 years.

As long as your house is a good candidate for solar, it’s at least worth considering. Use NREL’s PVWatts Calculator to estimate how much electricity a solar panel can produce over a year on your house — just type in your address. Project Sunroof is another free solar savings estimator.

Assuming an upfront purchase, it takes about 7 years to break even (when your savings with solar panels make up for the cost). On average, Arizona homeowners with solar panels can avoid $59,661 in total utility costs over 25 years.

Potential roof problems

As a rule of thumb, if your roof is more than 10 years old, consider fixing it before going solar. Installing solar panels on an old roof might mean you have to remove the panels, replace your roof and then reinstall the panels. This is an expensive and frustrating process.

One of the most common solar scams involves fake solar companies selling systems without any intention of really installing them. The other one is falsely claiming to be affiliated with state agencies.

In our experience, the best solar companies in Arizona have a few things in common: lots of experience, reliable equipment and transparent contracts. Here are some hiring tips.

• Check certifications: In Arizona, a contractor must qualify as a solar contractor to install, repair or alter residential solar devices. You can verify these through the Arizona Registrar of Contractors. We also recommend choosing an installer certified through the North American Board of Certified Energy Practitioners (NABCEP).
• Read reviews: Look out for red flags — complaints about misleading sales tactics, equipment failures, billing issues and lack of communication are common themes in negative solar company reviews.
• Ask questions: Do you need a solar storage battery, electric vehicle (EV) charger or critter guards? How does this affect overall pricing? What if your system needs maintenance? If you don’t understand something about the payment terms, warranty or ongoing services, ask for clarification.

How can I pay for solar panels?

Getting solar panels is like buying a car. Most people pay cash, finance or lease. Similar to leasing, a power purchase agreement (PPA) lets you get the benefits of solar without actually owning the equipment. Eligible homeowners can also borrow against equity in their house to finance a solar panel system.

• Solar loans work like any other type of loan. They have relatively low fixed interest rates. Once you pay it off, you own your system outright.
• Solar leases are a good option if you have limited savings and don’t want to take on debt; you also aren’t responsible for system maintenance.

You can combine local solar incentives in Arizona with the federal solar tax credit.

• State tax credit: You can claim 25% of your total solar system costs, up to $1,000, on your state taxes. Leased systems and PPAs are not eligible.
• Sales tax exemption: Arizona has a 100% state sales tax exemption on the purchase and installation of solar energy devices (up to $5,000 per device).
• Property tax exemption: Solar technology adds no taxable value for property tax assessment. In other words, your property taxes won’t increase just because solar panels increase your home value.

Federal tax credit

You should also use the federal solar investment tax credit (ITC). It reduces your federal tax liability by 30% of how much it costs to install solar panels.

The ITC drops to 26% in 2033 and then 22% in 2034.

The ITC is a credit, meaning it directly decreases the amount of taxes you owe. This is different from a deduction, which lowers your taxable income. For example, if you spend $10,000 installing a solar panel system, the ITC is worth $3,000. If you owe $15,000 in taxes, the ITC reduces what you owe to $12,000.
