*Prices are shown after applying the 30% federal tax credit.
As of Mar 2023, the average cost of solar panels in Attleboro is $2.82 per watt making a typical 6000 watt (6 kW) solar system $11,833 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.

I had a good feeling about this company from the very first contact. They were very open and honest about expectations and took the time to explain everything and answer my long list of questions and concerns. As an employee-owned company and a certified B Corp (look it up), I felt I was dealing with local people from my surrounding communities, and not some distant money driven corporation with pushy sales. After the initial visit, I received a full proposal within a day or two and was given the time to process, get additional quotes and do more research, without being hassled for a decision. In the end, the decision was between two proposals and despite ReVision being marginally more expensive and having a longer lead time for installation, I knew they were the right guys for my project. In addition, they had my panel of choice (REC) that the other vendor wasn't able to supply. I was also very fortunate that the initial lead-time was cut by several months meaning that I would be up and running for the peak summer months. The installation crew were a great bunch of guys and were on site for a total of three days. I talked to them often and was given regular updates and when they wrapped up, they told me what I could expect next. The only minor hiccup we had was that I was told that the paperwork for the change to a net meter (by the utility) would be submitted by the next day (after installation) and that the utility would have 10 working days to switch the meter. It actually took a whole week before the utility received the application and I did not receive a response from ReVision when I requested clarification on the submission. Perhaps some miscommunication? Luckily, the following week, I contacted the utility directly, who expedited the meter switchover and PTO, and everything was up and running within the 10 day period. The be fair, had ReVision not set the bar so high from the beginning, I would have normally expected such minor delays in the process from any vendor. All in all, I have been very happy with the whole process and outcome. Watching that meter "spin" backwards so much more than it does forwards gives a warm fuzzy feeling, and let's me know that I'm saving up credit for the winter. My calculations from the first few weeks of operation (sunny and cloudy days) helped validate the system sizing and the meeting of our goal to eliminate our bill completely. I'm confident that we'll even make a little revenue over the year as a whole. Definitely the right choice!

All Energy Solar was transparent through the whole process from sales to design, installation to all the approvals and state/local bureaucracy. They did a great job navigating my town's special requirements, Eversource's slowdowns, etc. My rep Carlo was helpful, responsive, and friendly and I'm going to miss getting update calls from him because he's so positive and always brought a smile to my day. The solar panels work great and also look really sleek.

In Feb, 2022, after researching several companies, I chose NEC to do the solar array on my Jamestown house. Engineer Artie Crocker was my contact person, who made a site visit, designed the array, and explained the system thoroughly. He was knowledgeable, patient, accessible, and always had time to take my calls, even on weekends. I had price quotes and site visits from two other RI companies (Sun Watt Solar and Newport Solar), but NEC was clearly superior in terms of price, quality of the panels, warranty, reviews, service and rebates. The project manager and installers were professional, on time and neat. In the 12 months since my 41 panels were in installed, I have had no problems and have accrued a $1,500 credit on my RI Energy bill. Because I chose "net metering" I can let the credit accrue, or I can donate energy to other RI Energy customers. I was able to give a $500 credit to a needy neighbor, which came right off her RI energy bill. I couldn't be happier with NEC and my decision to go solar. AAA+++

Greg Raffa was my primary contact and worked with me to negotiate the system and price, then walked me through the whole process and checked back in multiple times after project completion to make sure everything was operating smoothly and that I was able to take advantage of tax credits and other incentives. I've recommended Revolusun to friends looking to do solar.

After meeting with many solar companies, learning from what they told us and Not what they told us, we were discouraged....until we last met with New England Clean Energy! They were direct and educational, backing up their answers with specific facts, and respectful. Our panels look great on our roof too! The phone app is easy to install and use and is extremely fun to see our energy production, despite having a rainy, cloudy day! We can't wait till we have a sunny day!

This was our first foray into solar panels and I was definitely not sure it was the right decision. But I did my research and decided to go with Adam and the super team at Premier Improvements. Not only did they answer ALL my questions--and extremely patiently I might add--but they took care of everything, from discussing equipment choices, batteries, and sizing, to a superb installation both on the roof and in the basement. The installation is almost "elegant!" Then they took care of setting up the inspections with the town building inspector and the town electrical inspector. At every step of the process I knew I could reach out to Adam and the team with any questions, and they were always quick to respond. Incredible communication! Without question I highly recommend going solar with them. I thought solar would be a challenge because I've heard horror stories from people. And at times, particularly with our electricity provider, it was difficult to some degree. But that was minimized because we chose Premier Improvements. They're honest, straightforward, very accessible, and incredibly helpful! Go with Premier Improvements!

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 Attleboro 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 Attleboro.
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.
System information | Value |
---|---|
System Size (for 100% usage offset) | 8.11 kW |
Annual power generation | 12,343 kWh |
Pay-back time (assuming Cash purchase) | 8.7 Years |
Internal rate of return (IRR) on investment | 7.7% |
Gross cost | $19,820 |
Total Upfront Incentives and Rebates | -$5,154 |
Net Cost of System after rebated and incentives | $14,668 |
Total Cost of Utility Power Avoided over 25 years | $48,689 |
Please note that the investment return figures do not include the possible increase in property value
