*Prices are shown after applying the 30% federal tax credit.
As of May 2024, the average cost of solar panels in Arlington is $2.3 per watt making a typical 6000 watt (6 kW) solar system $9,652 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.

Out of the three bids for solar installation, we found A&R best aligned not only with our hopes for the project, but also with our values (employee-ownership, socially responsible). We found the drop-box of project photos and information after completion to be very helpful. We are also very happy with the installation now that we're live. We would absolutely recommend A&R.

I've had solar for three months and it has already surpassed my expectations. Earthlight was great to work with. They provided a time line for the installation process and met it perfectly if not ahead of schedule. Communication was great, workers were polite and neat, staff at the office were friendly and helpful. Overall a great experience.

Kirpal (owner of Oregon Solar Works) understands the systems he installs better than certain other companies that bid on my project. He asked questions to determine what my goals were as well what he thought I needed. We discussed the pros and cons of various set-ups and came to a system tailored to my wants, needs and new understandings. At no time did I feel pressured to go with a a stock system or hurry to lock in a "deal too good to miss". During the install Kirpal and his crew were great. All of them pay attention to details and keep the site clean. They took the time to answer any concerns I had or explain a detail that I was unfamiliar with. After the install and "commissioning" of the system, and after all monies had been paid, Kirpal was, and is, still quick to answer the phone or a text message if I see something unusual. My past jobs in high tech R&D required technical knowledge and attention to detail. I can be persistent at making sure those I work with deliver what is promised. I found Kirpal and his crew to be very professional, deliver on promises and a pleasure to work with.

Don’t be fooled by Intermountain Wind and Solar. They have good salesman but when it comes to installation and actually working with the company, they are the worst. We ha e to beg for an install date and then had to call and remind them we were there every step of the way. Please do yourself a favor and go with another company.

Left a big trench in our back yard, also cut into our tiling pipe and left it all that way. Now that my friend tried using them they came to hook her up and half of the power in her house isn’t working now and no one from this company will respond to her phone calls, text or emails.

Blue Raven Solar was everything I was expecting and more. I was in the loop from the time I met with my project manager. The texts and updates came frequently but not so much to be annoying. The installers, Angel Sanchez and Adrian Dar, were on time, they never once took a break and had everything completed at the time stated. Great job.

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 Arlington 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 Arlington.
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.
