*Prices are shown after applying the 26% federal tax credit.
As of May 2022, the average cost of solar panels in Phoenix is $2.55 per watt making a typical 6000 watt (6 kW) solar system $11,311 after claiming the 26% federal solar tax credit now available.
This is lower than the average price of residential solar power systems across the United States which is currently $3.00 per watt.
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.

From start to finish there were no surprises. Brad and Jesse keep us up to date on the status of every step of the process which made our experience hassle free. Brad the operation manager coordinated everything and was on top of all the details of the process. Brad's communication went above and beyond expectations. Jesse and his install crew were professional, on time and and took the time to answer all my questions. We turned on our solar system 2 days ago and we have already generated 117 kWh! We could not be happier. I highly recommend Arizona Solar and Energy for their exceptional service. They are definitely a 5 star company. You will not be disappointed!

Our solar purchase and installation with Black Platinum Solar was more than exceptional! The information provided during the sales presentation was easy to understand for a novice on solar panel energy and with no sales pitch pressure. The installation was completed as scheduled with a very good crew who kept the work area impeccably clean during and after the installation. Once signing the contract, we had nothing else to do as Black Platinum coordinated the required meetings with the City of Scottsdale and Arizona Public Service. We were kept informed of those meetings as well as installation progress. We have no regrets and only the highest of praise for Black Platinum Solar and recommend them to our neighbors and friends interested in solar panel energy.

There were a lot of steps in this process and each Sun Valley Solar representative (Bobby, Chris, Bill) I worked with was punctual, explained each step, and made sure they answered all my questions (even when I asked multiple times!). My coordinator, Misty, was exceptionally helpful and kept me informed of all steps and worked through several APS schedule challenges with a much appreciated sense of humor (I rated "On Schedule" a three out of five but this was entirely due to APS requirement changes after system installation). If you are thinking about installing a solar system, this is the company you want to partner with!

I feel truly blessed to have gone with Sunny Energy for my solar power! I was on the cusp of making a bad investment with another company for my solar needs and, truly Justin and Phoenix (Sunny Energy sales reps), really gave me the peace of mind that I made the right decision with them! They provided transparent, honest, sincere, and accurate information about the products they use, the services they provide, and the accessibility to them. They are local, not a third party seller like most other solar companies, they stand behind their product and the customer service at all stages and departments of their company is impeccable! From the owner down to the ground workers, they have been professional, kind, informative, and consistent across the board! To be honest, I really feel like they are family, and not a one in a life time sales pitch. They really do care! They are thorough in their approach and really want to provide a win win solution to everyone involved! I absolutely love that about them! I highly suggest Sunny Energy for solar, they are a wonderful bunch of people! How they have helped me and my family, I wish the blessings come in abundance for them ten fold! Thank you Sunny Energy for the pleasant experience, it went smooth, timely, and made a dream come true in my first home! I am truly grateful for you guys! Thank you!

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.

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.

Where there is no specific pricing information available for a brand then we have used state pricing data for that brand.
Solar panel manufacturer | Avg. cost per watt |

SunPower | $2.93 |
Panasonic | $2.83 |
LONGi Solar | $2.32 |
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!
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:
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 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.
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.
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, also called the ITC. The solar tax credit makes installing solar more cost-effective by providing homeowners with a tax credit equal to 26% 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.
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.
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.
