*Prices are shown after applying the 30% federal tax credit.
As of Jul 2024, 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.

The team at Mass Renewables was a pleasure to work with. From the early estimating and vetting process, through panel layouts, permitting, scheduling of the work, and everything else, the team did an exceptional job communicating and answering all of my questions. The quality, price, and timeliness of the work was great and I am happy with my system. Almost 2 years after the original install, my system has been underperforming a bit and the team is still working with me to troubleshoot an issue with two panels and potentially add an additional panel to help. All in all, I am impressed with Mass Renewables and would recommend them for your solar needs.

Installation went very well. Crew arrived on day expected and went right to work. The team was prepared, listened to our concerns, was respectful to neighbours and our property. They worked safely and paid attention to details. They made sure to let us know when leaving and what time they would be back to the work site. Appreciated the team lead’s willingness to listen and present alternatives. The electrician took time to outline where the boxes could go and made suggestions when there was an option. The equipment looks great and the supporting boxes blend in. The panels themselves fit in well without calling attention to them—looks designed in not added on. Worked was completed ahead of time and passed inspection today. We highly recommend All Energy Solar for the expert planning and installation. These folks are organised, sensitive to homeowner’s input, and a safe, well considered installation.

NEC Solar did solar panels for our primary residence a couple of years ago. It was a great experience with Artie as the company representative. Communications were quick and clear and he explained every steps of the project and met all the timelines We have been so pleased with our solar panels and the amount of power production that decided to do the same for our vacation home. NEC Solar was the first company we contacted.

I have yet to have multi-day power outage since installing 2-13.5 kwh SunVault batteries. During winter months I leave fully charged since sun & possible snow cover will impede solar production, so a fail-safe for the long power outage possibility. Now that better weather is here and not worried about freezing pipes, I am running the batteries overnight to power the home. So far, has the SunVault system has been working great with balancing the battery, grid and solar production usage in the home. I use about 50% of the batteries (one battery) each evening and it is typically charged up by 11 am local time, a little later on the cloudy days (yes, arrays still produce). My system is sized enough to power home on all but the darkest days where the battery supplements. If we get multiple days of rain, then I'm back on the grid using some of the credits I have stored at Eversource after the batteries are 100% recharged each day. I have no idea when the SunVault system switches to battery from the grid and vice versa, no issues with any electronics in the home when it does and it works in the "normal" daily living space fantastically. I will update this review if my micro-grid fails during a multi-day grid power outage as it is my expectation the solar array will not be shut down so the house and batteries can use the produced electricity until the grid is repaired. This is the real reason I go the batteries as had a 2018 summer Tropical Storm knock out power for 6-days and it was sunny for 5 of those days but my solar array was useless without a battery system attached. Fingers crossed this works as promoted and promised. The staff was great at every process of the sales, install and post-install support process as there are always questions and weird things with electricity that sometimes needs a call. Thank you, Jordan, my install team and Kim for helping and teaching me about the system. SavKat is a local, family-owned operation that is simply the best, highly recommend talking to them before going too far into your solar planning.

I deal with many subcontractors at work and can honestly say that your installation crew totally impressed me with their quality, organization ,cleanliness ,politeness and instructions. It was a great experience working with all of you. The system seems to be performing better than I was promised. So far all negative Eversource bills. Thank you so much Paul

From start to finish this was an exceptional process. It was a throwback to a time when customer service was all about the customer. We were kept informed every step of the way, called if there was a delay for any reason, work was done timely, staff were more than competent and I was completely comfortable having them in and on my home. The work area was always cleaned before they left for the day. It was so refreshing to work with a company that does quality work, with quality products and cares about the client experience from start to finish.

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 | $3.29 |
Panasonic | $3.17 |
LONGi Solar | $2.53 |
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
