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 residential solar installation costs $7,637 to $21,821 in Glendale
Jump to insightWith electricity costs continuing to rise, many find it’s financially worth it in the long run.
Jump to insightFederal and local financial incentives can make solar more affordable for residents. You can also lease a system with little upfront costs.
Jump to insightA 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
5 kW | 6 kW | 7 kW | 8 kW | 9 kW | 10 kW | |
---|---|---|---|---|---|---|
Before federal tax credit | $10,911 | $13,093 | $15,275 | $17,457 | $19,639 | $21,821 |
After federal tax credit | $7,637 | $9,165 | $10,692 | $12,220 | $13,747 | $15,275 |
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 6.9 years to break even (when your savings with solar panels make up for the cost). On average, Arizona homeowners with solar panels can avoid $65,970 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.
» SHOULD YOU: Replace your roof before going solar?
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.
» TIPS: Get the best solar quotes
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.

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

No, homeowners associations in Arizona are not permitted to unreasonably restrict solar energy systems.

You need building and electrical permits through the City of Glendale Planning and Development Services Department. After installation, you have to schedule inspections with the City of Glendale to ensure compliance with building codes and safety standards.
We’re not aware of a totally free solar option in Glendale. You can lease or enter a power purchase agreement with minimal upfront costs. There is usually a low ongoing monthly fee. In general, beware of deals that sound too good to be true.
A third party installs and maintains solar panels on your property. You buy the power generated by the panels on a per kilowatt-hour (kWh) basis. It’s typically a fixed price, with a cheaper cents/kWh rate than traditional utilities have for the same amount of electricity.
Net metering lets you earn credits for sending any excess solar power into your local grid. Arizona technically has a system called net billing. This differs from net metering, where customers would get paid the full retail price for their extra electricity. Net billing pays a lower rate, which means customers earn less for the excess power they produce.
Monocrystalline and polycrystalline are the most common types of solar panels used in residential installations. In general, monocrystalline panels are considered the best bang for your buck. Cheaper solar panels are typically polycrystalline. The key difference is in materials and efficiency: Monocrystalline panels use pure, single silicon crystals, while polycrystalline panels are made from melted silicon fragments, resulting in different efficiency levels.
Solar panel efficiency is a measure of how well a panel makes electricity. Standard efficiency rates range from 19% to 23%, which means 19% to 23% of the sunlight that hits the panels gets converted into electricity. The more efficient the solar panels you buy are, the fewer panels you need. While more efficient panels cost a little more, you save by buying fewer panels.
The ConsumerAffairs Research Team used a research-backed, data-driven approach, which was informed by our expert editors, to choose the best solar companies. We prefer to recommend those with a longer time in business and a solid track record of reliability in Glendale, Arizona. For this guide, we objectively weighted several key features to get our final rankings:
Reviews, ratings and testimonials: 40%
We analyzed solar company reviews by verified solar customers to gauge real-world satisfaction. Companies with generally positive feedback on our site scored highest in this aspect. Those with the most 4- and 5-star reviews by verified Glendale customers were given preference.
Warranties: 20%
A long warranty is important — it shows that a company stands behind its products and services. We compared companies on both equipment and craftsmanship warranty terms. All of our top picks for professional installation have warranties or production guarantees of at least 10 to 25 years.
Equipment selection: 20%
We evaluated each company’s selection of solar panels, storage batteries and inverters. Those with proprietary technology or a wide equipment selection from trusted brands ranked highest.
Financing and payment options: 20%
We gave preference to companies that offer multiple payment and financing options for transparent terms and conditions.
