Solar panel installation cost in Phoenix
The size of a solar panel system also plays a role in how much the installation will cost.
Larger solar installations will typically have a lower cost per watt, because the panels can be purchased at a ‘bulk price’. However, these larger solar systems will still have a higher total cost, because they are made up of more individual panels.

Black Platinum installed our system here in Anthem, Arizona in 2009. We later expanded our system with them in 2013. I soon realized they were the most trustworthy and helpful contractor firm of any kind that I have ever dealt with, and I have had many over many years of home ownership.

There were a lot of great reviews for Sunny Energy when we decided to go with them in December of 2022 and it was one of the reasons why we decided to go with Sunny Energy. I was most impressed by people saying what a great service experience they received. It's now May of 2023, the solar has been installed for about two months. The one hiccup we had with Sunny Energy was in regard to the contract. We were told one payment schedule on the phone and when we received the contract it was a different payment schedule. The salesperson explained that they had changed their payment schedule two weeks prior, and he had unfortunately forgot to quote us the new schedule. After the contract was signed the process was fast and Sunny Energy did everything they needed to do and there were no delays on their part. Everyone communicated along the way. All the communication was professional and timely. When there were delays in the process it was in no way Sunny Energy's fault. The biggest delay was after the system was completely installed and we had to wait for APS to give the Permission to Operate. In fact, once they had approval and permits and could move forward with the installation, they had an opening and they installed four days later. The crew that came out to do the installation was great and did a good job. They were easy to talk to and listened to what we had to say. The installation was rather painless and went well. After the system was installed, we received a phone call and email from what I believe is the head of customer service to schedule a virtual walk through. When we didn't respond and book a virtual walk through on the first email a second one came which was a great follow up. However, I would have preferred an in-person walk-through. I made the mistake of not asking if one was possible and it turns out after talking to Sunny Energy after the fact, I could have requested one. By that time the email asking to schedule came with a link to a video of the walk through and that had enough information, so it wasn’t an issue thereafter. Our solar system is generating enough energy now that we are receiving credits from APS and electric bills for $0 with additional dollar credits still on file with them. I am pleased with the solar system that was purchased, the time to install, the work that was done and the system is operating as promised. I am also thrilled with the SolarEdge inverter and the app that goes with it and would highly recommend that people ask for the SolarEdge inverter and support equipment. If I need any additions to my solar system in the future, I will not hesitate to contact Sunny Energy.

We contracted w/ TFS at the end of 2019. Then the pandemic hit and we weren't sure what was going to happen to our business. TFS was willing to put the solar installation on hold until we were ready, no pressure to move forward. We eventually got back on track and had our solar installed. It works great! Our electric bill last month (July) was $18.

We received 4 quotes, with Net Zero Solar giving us the best bid. There was one national company, Sungevity, in the mix of bids (since gone out of business) with by far the highest quote. The other quotes were reasonably within range, but Net Zero Solar had the most complete bid and information. Installed in 2013, we have had no problems with the LG panels or Enphase microinverters, or any other part of the system. We have already broken even and are enjoying a great photovoltaic system. The staff there is great -- I highly recommend them.

We highly recommend Sun Valley Solar Solutions. We selected Sun Valley after reading extensively and interviewing six firms. Sun Valley stood out for providing unfailingly accurate, credible and useful information. We liked that Sun Valley is a local company with roots and a solid presence in Arizona and many years of solar experience. We're now operational and can say that every step of the way, Sun Valley confirmed that we made the right choice. Every Sun Valley person we worked with through the proposal, design, installation, and commissioning impressed us with their knowledge and commitment to getting the details right. All were wonderfully agreeable to boot. Thanks so much to Sam and Adrianne, and forgive us for not calling out each other contributor by name! Thanks to you all!

Straight talk, no jive, no hard sell, no hidden details. Best price (on best quality components) among half a dozen that I talked to. I was able to pay cash avoiding the extra cost and hassle of a loan or lease. Good workmanship, showed up when they said they would. System has worked well and I haven't paid APS a dime since it was installed end of September. These guys are a fine local company, I have only good things to say about them.

How much do solar systems using the most common brands of solar panels cost in Phoenix in 2023?
Where there is no specific pricing information available for a brand then we have used state pricing data for that brand.
Table 2: Local solar panel manufacturers
| Solar panel manufacturer | Avg. cost per watt |
|---|---|
| Canadian Solar | $2.39 |
| LG Solar | $2.80 |
| SunPower | $2.93 |
| Panasonic | $2.83 |
| LONGi Solar | $2.32 |
Why solar panel cost should not be your only consideration when buying solar panels for your home
The most important difference between buying solar panels and any other purchase is that solar panels last 25-30 years. This is a long, long time and you will need customer service over all that time. The reviews below of the two largest corporate solar installation companies indicate larger corporate solar companies are not delivering this support to their customers.
We recommend you find a small or mid-size, local, family-owned solar company. These companies tend to care more about you and your specific job. You don't want to be on hold to a corporation's call center for the next 25 years!
What other factors affect the cost of solar panels for your home?
The cost of solar doesn't just include the equipment and installation costs - it’s also made up of permitting costs, inspection costs, and installer profit margins.
These different components are what make the price of solar fluctuate between installations. Some of the factors that affect solar power system installation costs for specific homes include:
The amount of electricity your home uses
Homes that use more electricity will need more solar panels to cover their energy needs.
Although solar panels do get cheaper on a per-watt basis, the overall cost of the system will increase as more panels are added.
But, the higher a home’s energy usage, the more solar panels can save the homeowners on their energy bills.
The type of solar panels you buy
The price of solar panels can vary depending on the type of solar panels you choose.
There are two main types of solar panels for residential solar installations: monocrystalline and polycrystalline. Monocrystalline solar panels tend to be more efficient and more expensive than other solar panels. Polycrystalline panels have a lower efficiency rating and come at a lower price point.
The type of inverter you buy will also influence the cost of your solar system.
The quality of your solar installation
You may see some solar quotes with prices that seem too good to be true.
If you get quoted for a ridiculously cheap price, the installer might be using low-quality equipment or an unsustainable pricing model. You want to use a solar installer that is charging enough so that they can stay in business - as you’ll be relying on them for the next 25 years!
It’s important to make sure that your installer is giving you the best quality at the best price possible. This is why getting multiple solar quotes is so important.
Federal, state, and local solar incentives
The overall cost of solar can be influenced by the solar incentives available.
Across the U.S., homeowners can apply for the federal solar tax credit. The solar tax credit makes installing solar more cost-effective by providing homeowners with a tax credit equal to 30% of the cost of their installed solar panel system.
Local solar tax incentives and rebates can end up saving homeowners thousands on a solar installation, especially when they’re used with the federal solar tax credit.
See what solar incentives are available in your area by using our solar panel calculator.
How is the cost of solar panels offset by solar tax credits in Phoenix?
The cost of installing residential solar panels in Phoenix varies with the brand of solar panels and inverters you choose, the installation company you choose to install them, the relative ease or difficulty of installing solar panels on your home, and of course the amount of solar panels you need. The amount of solar panels you need is, in turn, related to your energy usage.
Are solar panels worth it in Phoenix in 2023
The table below shows the data extracted from a real life quote delivered through the SolarReviews marketplace recently for a fairly typical home in Phoenix.
As you can see the payback period is relatively short and equates to a much better return on investment than he historical returns that have been available from investing in things like shares or property.
Table 2: Cost, savings and payback period for an average residential solar system in Phoenix
| System information | Value |
|---|---|
| System Size (for 100% usage offset) | 9.22 kW |
| Annual power generation | 14,328 kWh |
| Pay-back time (assuming Cash purchase) | 8.1 Years |
| Internal rate of return (IRR) on investment | 8.8% |
| Gross cost | $21,146 |
| Total Upfront Incentives and Rebates | -$5,497 |
| Net Cost of System after rebated and incentives | $15,646 |
| Total Cost of Utility Power Avoided over 25 years | $54,436 |
Please note that the investment return figures do not include the possible increase in property value
