*Prices are shown after applying the 30% federal tax credit.
As of Oct 2024, the average cost of solar panels in Flagstaff is $2.62 per watt making a typical 6000 watt (6 kW) solar system $11,007 after claiming the 30% 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.

Arizona Solar Wave was very thorough when installing the panels on top of the house. They guided me through the process of getting all the necessary paperwork into the various HOA's and APS. The only problem now is understanding the Enphase Energy System and getting it set up properly. Once this gets set-up, my experience will be 5 stars.

We first met Black Platinum Solar in 2009 and after a very lengthy due diligence process decided to choose them to install our Photovoltaic Solar System in 2010. They did a panel expansion for us in 2013 then an inverters upgrade in 2018. Every time we've worked with them we feel so thankful that we found them... which is now 15 years ago. Continued superior customer service. We wouldn't even consider using a different company for any future solar needs.

I am unhappy with the installation and this companies disregard for customer satisfaction. And they know I am and they knew I was before the installation was done and they DO NOT CARE. I was told in the beginning I would not see panels from the front of the house. I caught the problem during the install (I could that I would be able to see panels from the front of the house and from my pool.) They said "let us finish this part and we will come back and fix the issue." Stupid me believed them - they did not. I paid around $80k for the system and I was told it would be around $1,300 to move the offending panels - but I would have to pay the cost. They did not even offer to split the difference with me. Their solution - lay the panels flat (which they and I know makes them less efficient - aka I pay for that in the long run with less production and then requires more cleaning). I pointed out that for a measly 1300 they could have a very happy client. They did (do) not care. So now I have a bunch of flat less efficient panels that I can still see - just not as much. Will I use them for anything ever again - NO! Not even panel cleaning. I used Hot Purple for my first house and I wish I had used them for this one.

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.

I have a very negative review of this company (Sunny Energy), due to the fact that after installing my solar system in which was done seamlessly without any hiccups, there was a $8,000.00 built into my loan for purchasing a Generator. I have tried to contact the company and the contractor to resolve this issue without any success. I would not recommend this company to anyone.

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.

Dave is a professional. He is not only very knowledgeable about solar, but is an excellent communicator, honest and has a team of very hard working individuals. They are thorough, and respectful of your property. Dave returns emails and phone calls in a timely manner. I would highly recommend him. I interviewed several companies, and his company was by far the best.

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. 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.
The cost of installing residential solar panels in Flagstaff 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 Flagstaff.
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.
