How Long Does it Take for Solar Panels to Pay for Themselves in Barnstable County?

In Massachusetts, the average payback period for solar panels ranges from 5 to 8 years. Your payback period will be determined by the cost of your system as well as the amount of power it produces. The more energy your system produces, the quicker it pays for itself.

The "solar panel payback period" is the time it will take you to ultimately pay off your solar power system through electric bill savings.

It is calculated by taking the total cost of installation and then deducting solar incentives and/or rebates, as well as monthly electric bill savings until the total cost is paid off.

For example, if you spend $16,000 on a solar panel system in Barnstable and receive a $4,800 tax break, the total cost after incentives is $11,200. If the solar energy produced by your panels reduces your annual electric bill by $1,500, your payback period would be approximately 7.5 years, assuming electricity rates do not rise.

What factors must be considered when calculating a solar payback period in Barnstable?

Five major factors influence your solar payback period:

  • How much electricity do you use?
  • How much does the solar plan cost?
  • What are the solar rebates, incentives, and tax breaks worth?
  • What is your system's output?
  • What is the cost of electricity in your area?

What are the Incentives for Solar energy in Barnstable County, Massachusetts?

Massachusetts Solar Tax Credit

Massachusetts' most alluring solar tax credit is the Personal Income Tax Credit, also known as the Residential Renewable Energy Income Tax Credit. Residents of Massachusetts can claim a tax credit on their income tax return equal to 15% of the system's cost (up to a maximum of one thousand dollars) if they install a solar energy system at their primary residence.

Since 2016 when this tax credit was first implemented in Massachusetts, the price of solar panels has been reduced for individual homeowners. The effect has been consistent and noticeable, which is likely why solar installers in Massachusetts have been in such high demand. As such, it's a powerful argument in favor of switching to solar power or some other renewable energy source.

Solar Massachusetts Renewable Target (SMART) Program

The Solar Massachusetts Renewable Target (SMART) Program provides direct incentives for residential and commercial solar energy systems connected to one of the state's three investor-owned electric utility grids: Eversource, National Grid, and Unitil.

This program, implemented in late 2018 by the Massachusetts Department of Energy Resources (DOER), directly compensates solar panel owners for the electricity their systems produce for ten years. The Department of Public Utilities then granted permission to increase funding by late 2021. These rebates go by a few names: "Solar Renewable Energy Credits" or "Solar Renewable Energy Certificates" (SRECs).

It all depends on the utility company and the size of the system, but customers can expect to be paid anywhere from $0.22 per kWh to $0.34 per kWh for the energy they generate.

As an added bonus, the SMART program offers increased compensation for installing a battery storage system.

Solar panel systems already have a payback period of fewer than ten years due to reduced electricity costs, but the SMART program's additional incentives can nearly halve that time.

Massachusetts Solar Tax Exemptions

Another way for the state of Massachusetts to ensure that the cost of solar panels does not deter residents from investing is through direct tax exemptions.

While most products in the state are subject to a 6.25% sales tax at the point of sale, this tax does not apply to solar energy systems.

Massachusetts Net Metering Program

Through net metering, properties that generate their own electricity can get paid for sending power back into the grid that they don't need at the time. This can be done with solar panels or other means.

Federal Solar Investment Tax Credit (ITC)

Customers who install solar energy systems before December 31, 2032, and meet other requirements, can claim a 30% tax credit against their federal tax liability thanks to the Investment Tax Credit (ITC). The tax credit for 2033 system installations is 26% of the system's total cost. The tax credit will be worth 22% of the total system cost in 2034, and it will be phased out in 2035.

Do You Need a Handyman or a Solar Installer in Barnstable County?

According to the United States Office of Energy Efficiency and Renewable Energy, a trained professional is recommended for performing solar system installation. This viewpoint is consistent with Massachusetts state law, which mandates the installation of solar PV systems by qualified electricians. In addition, many installers participate in training and certification programs, such as those offered by the North American Board of Certified Energy Practitioners (NABCEP).

Do Solar Panels Increase a Home Value in Barnstable County?

Yes. Studies have shown that installing solar panels is just as good for a home's value as putting in a new roof or plumbing system.

From 2002 to 2013, the Lawrence Berkeley National Laboratory (Berkeley Lab), which is part of the U.S. Department of Energy, undertook the largest-ever study of solar homes in eight states to find out how much adding solar panels affects home buyers. It found that buyers in six states were willing to pay $15,000 more for homes with solar panels than for similar homes without them.

More studies have shown that these increases in home value are directly linked to your electric bill and the amount of energy you save over time. The National Renewable Energy Laboratory (NREL) shared information from a study that was published in The Appraisal Journal, a quarterly academic publication of the Appraisal Institute, the largest professional group of real estate appraisers in the United States.

This 2008 study found that for every $1 cut in annual utility bills, the value of a home goes up by $20. So, a solar energy system that saves a homeowner $500 per year can add $10,000 to their home's value.

Because of this, sellers and real estate agents can ask for more money for a home. A home that is good for the environment and saves money on energy costs is suitable for both buyers and sellers.

Are Solar Panels Exempt from Property Taxes in Barnstable County?

Under Massachusetts law, solar energy systems and wind energy systems used as a primary or auxiliary power system for heating or otherwise supplying the energy needs of taxable property are exempt from local property tax for 20 years.

In 1975, Massachusetts became the first state to provide a property tax exemption for solar and wind energy systems. The initial law exempted such systems from taxation for 10 years; the legislature later amended the statute in 1978 to extend the exemption period to 20 years.

However, this incentive only applies to an eligible solar system's value added to a property. It does not entitle you to a full exemption from your property tax bill.

Any energy system component that serves dual functions (for example, structural and energy) is ineligible for the exemption. Windows, thermal drapes, and floors, for example, are not covered by the exemption. Thermal storage rods, storage boxes, fan systems, and ductwork that serve solely as part of the energy system, on the other hand, are exempted.

How to Find Solar Companies Near Me in Barnstable County, Massachusetts?

The most efficient way to locate solar providers in Barnstable is by navigating through online marketplaces. You will receive multiple binding quotes from a network of certified solar installers. (Binding signifies that the price you see is the price you will pay — not a lowball estimate)

Online marketplaces only require a few quick steps:

  • Create a profile by entering your zip code and answering a few questions about your home and energy bill.
  • Next, use their online solar savings calculators to view preliminary estimates and potential savings.
  • Schedule a call with an Energy Advisor to discuss your objectives and commence your guided experience.

How to Find the Solar Companies Near You On Your Own

Step 1: Online Search

Start by searching Google for "solar providers near me." You will be presented with a variety of sponsored listings, maps, and guides.

If your results are similar, you may need to go to the second, third, or fourth page to locate actual solar providers in Barnstable, Massachusetts. Create a list of a dozen or so companies to research once you have located them.

Step 2: Certifications and Licensing

When searching for solar providers in Barnstable, Massachusetts, an essential factor to consider is whether or not they possess the necessary licenses and certifications. An electrical license is an absolute requirement.

The North American Board of Certified Energy Practitioners (NABCEP) Certification is a significant plus (and a requirement to be on Solar.com's platform) for an installer.

When searching for local installers, ask if they are NABCEP-certified or look for the logo on their website.

Step 3: Online Customer Reviews

Looking at online reviews is the next step after narrowing your search for a solar company that is certified and licensed.

For the most reliable reviews of solar companies, it is recommended that you check Google, Yelp, and the Better Business Bureau.

Always use your discretion when reading online reviews, as some may be hyper negative or positive. You can get a good idea of the installer's effectiveness by reading reviews from multiple sources. Consider more than just the price of the solar panels and the installation when deciding on an installer.

You can take it a step further by asking to speak with former clients of the solar installer in question who are willing to share their experiences with you as references. This can help you gain a deeper understanding of the service they provide.

Step 4: Solar Panels, Equipment, and Finance Offerings

Depending on where you are in the process, it may make sense to limit your search for a solar energy provider by location to those specializing in the type of solar panels you need or offering the financing you can afford.

Different installers may provide different solar equipment and payment plans. For instance, SunPower panels can only be set up by trained professionals. If that's crucial to you, check out the installer's website to see what kinds of solar panels they sell.

Step 5: Get Multiple Quotes

It's time to pick up the phone and start scheduling meetings with installers once you've narrowed your list down to a manageable number.

What Energy Companies offer Solar Rebates in Barnstable County, Massachusetts?


SunPower has been in business for nearly three decades and has become the industry leader in solar energy. SunPower is a good option for Massachusetts residents despite being a national company, as the state's excellent solar incentives program helps to offset the high cost of SunPower's premium panels.

SunPower panels are among the most expensive in the nation, rendering the initial investment too costly for some Massachusetts residents. Despite its high prices, the company offers an exceptional array of solar services and multiple financing options.

SunPower offers both purchase and financing options for solar systems. SunPower offers solar leases in which you pay a fixed monthly amount, but it does not provide a power purchase agreement in which users pay based on the number of kilowatt hours used.

Momentum Solar

Momentum Solar is distinguished from its competitors by its exclusive operation in jurisdictions that enable net metering. Consumers can sell any extra energy their solar panels produce to a utility company. It's an intriguing point of differentiation that could influence some prospective consumers, as Momentum can walk them through solar's financial aspects better than its competitors.

Momentum Solar does provide cash, solar loans, PPA, and solar lease financing alternatives, although some, such as solar loans and leases, may not give homeowners tax incentives.

Momentum does not offer immediate quotations or online pricing despite its desire to help customers save money on solar panels. This is likely due to the fact that state-specific tax credits differ.
