*Prices are shown after applying the 26% federal tax credit.
As of May 2022, the average cost of solar panels in Attleboro is $2.82 per watt making a typical 6000 watt (6 kW) solar system $12,509 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.

I primarily picked this company because they *dont* subtract out the work and because they're extremely local, and I'm glad I chose Mass Renewables! After reading horror story reviews about *other* companies where people were complaining about all sorts of things from: the solar installer subcontracting out all the work to people who proceeded to do various things terrible things. Or of companies 50+ miles away for whom the communication becomes awful after receiving the payment. I'm happy to say none of that happened with them. The sales process was smooth. They didn't try to push any particular system config in order to make me spend the most. In fact, after doing the survey, they lowered the number of panels because it would have generated more than I needed. The price was exactly as quoted, spread out among three payments throughout the process of the project. Nothing at all to complain about in the whole planning and post-installation process. They actually opportunistically did the installation about a month ahead of schedule because my roof was clear of snow and their originally scheduled job wasn't! The installation was quick and seemingly high quality. Everyone doing the installation that I talked to was pleasant and very informative. The system wasn't actually producing energy something like 2 months after the installation because of delays from National Grid and the town inspection. You can't at all blame them for that, but I think it's an important point of information for people to be aware of. You'll be all excited about the installation, and then will have to wait for annoying things outside your/their control before it's generating electricity. But now that it's on, it's (so far) exceeding my expectations!

We are thrilled with our panels and the ReVision Energy Team. The options were clearly laid out and they presented models of energy capture given our roof configuration. And the Installation team was terrific. They worked hard, thought through some challenges, and in the end came up with a spectacular result. The connecting wires are largely hidden and those that were necessary are only visible if you look for them. We did not expect it to look so good. During the process there were some COVID delays and the team stepped up to mitigate them. As family and friends see our panels, I am steering them to ReVision Energy.

I had solar panels installed at my house last year by NEC Solar and everything went perfectly. Dana did a great job explaining everything to me and my wife to make us feel at ease and I feel confident that the products they used will preform for the life of the system. The installers did excellent work, were very attentive to our needs and the system looks and works great. We were concerned with the aesthetics and didn't want pipes running on the roof so they ran all the wires through the attic and walls. The system was sized properly and I generate plenty of electricity to cover my whole electric bill, it's nice not to have to pay an electric bill or have to worry about price increases. Great job NEC Solar!

We did a lot of research and chose Revolusun because of all the great reviews and the best warranties of all the other companies, and the fact that they are local and do all the work themselves. Price was about average for the higher end companies, and well worth any difference. Solid technology and great installation team. They handled all the permitting and other headaches, and entire team was totally professional, ready to answer all questions and concerns. Now when driving around and looking at other installations, we are really glad we chose them as our installation is clearly neater and looks great compared to others. You won't regret working with these guys.

We were always intrigued by the idea of solar, but were wary of the price and the headaches with installation and getting permits. Insight Solar made it all super easy and convenient. Adam, Christina, Leah and the Insight team handled everything from the initial consultation to the permits to the financing to scheduling our installation. Our biggest concern was that we needed a new roof before getting the install done. Insight even handled scheduling that part of the process for us. It was also more affordable than we expected (even with the new roof rolled in). Best of all, we're expecting to save around $1200/year (even with our loan) and be able to 100% offset our electric output with our new solar system. Our only regret about solar — we wish we had this done 10 years ago.

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.
