Solar panel installation cost in Attleboro
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.

Mass Renewables came recommended and they lived up to all expectations. They were willing to work with us on system and contract details and fielded all of our many questions promptly, accurately, and pleasantly. The crew on-site was very considerate and helpful in explaining the their process, sought input when options were available, and stayed in touch during the installation. They also left the worksite immaculate.

I had a very good experience with Certasun going through my first ever solar installation. Paul was less of a sales person than a solar evangelist giving me the confidence to move forward with the solar project. Their team of project management handled all aspects of site assessment and obtaining required permits much faster than anticipated. Installation of the panels and net-metering connection was well organized and executed in half-day. Everyone I interacted with were very knowledgeable and patient to answer my questions very thoroughly.

Installation was conducted back in April 2020 just as the COVID panic was rearing its ugly head. Crew worked efficiently and job was completed in one day. Schedule was mutually agreed on so that failing asphalt roof could replaced with standing seam prior to installation. A real plus was that all permitting and interface with the power company was taken care as was tax related paperwork. They did it all. Now it’s January and I’m enjoying electric heat in my workshop that was actually captured and banked last summer. Professional installation in every respect. Right down to being ready for code enforcement inspection. Highly recommended.

I made my decision to use RevoluSun in part because of Richie Bonney, the sales rep. He's incredibly knowledgeable and really good at answering questions/explaining things and made the other reps look like chumps in comparison (I say this tongue-in-cheek but it' true, frankly). I received 4 solar quotes. While at face value (gross system cost) RevoluSun looked more expensive, when I drilled down into the numbers it turned out to be the most reasonable when comparing KW size to system cost, so I urge folks to look carefully at those components when making a decision. The Solaria panels I got are supposed to be advantageous in part because the rail system holds up to snow and ice expansion/contraction better than traditional systems since there are fewer penetrations in the roof. That makes sense to me, though I can't speak to being able to witness the difference myself, exactly. RevoluSun was responsive throughout the process when I had questions, going through the process of setting up the system with my utility (no small feat), and walking me through the system once I went through my first bill cycle to be sure I understand how to track it and such. All in all I am quite happy with their product. I bought a hybrid vehicle about a month ago and the system easily pays to run that, as well, and I love to get my negative electric bills and checks every month.

I began my process with New England Clean energy in July of 2020, and was finally approved for electrical use in Feb 2021. The team came in October to do the initial install, which was done without measuring the roof, and could have fit an additional solar panel. After installation we had national grid come and look at the install in November, and the way they connected the meter was wrong. After changing the way the meter was connected national grid came out again to look and there was another problem with the way they had installed the meter again in December. Then in January when national grid came again to review they had incorrectly labeled the meters. They tried to then relabel them and send a review which failed, and needed to send someone out again. Finally in Feb I was fully approved. During the struggle with National Grid New England Clean Energy didn't seem knowledgeable about the issues that were going on and what was causing National Grid not to approve this install. Between the stickers mishap I turned on and the meter to track how much usage I was losing due New England Clean Energy mistakes. I calculated it at 150ish dollars and asked New England Clean Energy to pay me that sum. They agreed to pay that sum, but it's now been two months and they've stopped all communications with me. I wouldn't hire them again nor does it appear they know how to correctly perform an install in RI.

I wasn't thinking of going solar until an unsolicited person knocked on my home door and asked if I wanted a free estimate on solar. Although I was sold on the idea, I wanted to find out any good reviews on them so I posted an ask on Facebook Needham site for reviews on good Solar vendors, and an overwhelming majority of responded that NEC Solar with Artie Crocker was by far the best Solar experience they had, so I was comfortable choosing NEC with Artie as my Solar vendor over that unsolicited salesperson who introduced me to the idea.

I spent almost 14 months researching solar companies. Having them come into my home and selling me on their systems. But instead of selling me, SavKat did something quite remarkable. They “shared” with me why they were my best choice. They were true to their word in every way. It could not have gone smoother or their crews been more professional. They kept their word every step of the way and the knowledge that they are a local company that will be there for me over the next 20 years, played a big role. Everyone will be going solar. The decision left to be made is with who. Call SavKat Solar today and let them share with you why it should be them.

How much do solar systems using the most common brands of solar panels cost in Attleboro in 2021?
Where there is no specific pricing information available for a brand then we have used state pricing data for that brand.
Table 2: Local solar panel manufacturers
| Solar panel manufacturer | Avg. cost per watt |
|---|---|
| Canadian Solar | $2.63 |
| LG Solar | $3.13 |
| SunPower | $3.29 |
| Panasonic | $3.17 |
| LONGi Solar | $2.53 |
Why solar panel cost should not be your only consideration when buying solar panels for your home
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!
What other factors affect the cost of solar panels for your home?
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.
Chart 2: What is the breakdown of cost in an installed residential solar system? (cents per watt)
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:
The amount of electricity your home uses
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 type of solar panels you buy
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.
The quality of your solar installation
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.
Federal, state, and local solar incentives
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.
See what solar incentives are available in your area by using our solar panel calculator.
How is the cost of solar panels offset by solar tax credits in Attleboro?
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.
Are solar panels worth it in Attleboro in 2021
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.
Table 2: Cost, savings and payback period for an average residential solar system in Attleboro
| 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
