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

Incentives are offers that the government uses to encourage homeowners to opt for solar energy. The federal government and Massachusetts state government offer various incentives to increase the adoption of solar energy. They include:

Federal Solar Investment Tax Credit

The Federal Solar Investment Tax Credit) is one of the most popular and most utilized incentives for installing solar energy in Massachusetts. This credit is only available to those who buy a solar energy system outrightly, through cash or a loan.

How to get the Federal solar tax credit.jpg

The tax credit allows buyers to claim 30% of the total value of the solar energy system. This tax credit was introduced in 2006 and was initially set to phase out. However, with the signing of the Inflation Reduction Act, the tax credit period was extended from 2022 to 2032.

In 2033, the tax credit will reduce to 26% and drop to another 22% in 2034. In 2035, it will expire, except if Congress decides to extend it again.

Residential Renewable Energy Income Tax Credit

The Massachusetts Residential Energy Credit allows residents who purchase a home solar power system to claim 15% of its value in tax credits.

Buyers can only claim up to a maximum of $1,000. Any tax credit you don’t use can be carried over and deducted from your personal tax for up to three years.

Solar Massachusetts Renewable Target (SMART) Program

This incentive was launched by the state of Massachusetts’ Department of Energy Resources (DOER) in 2018. It’s available to customers of Eversource, Unitil, and National Grid.

Under this incentive, homeowners can receive between $0.19 and $0.31 per kilowatt hour of energy that they produce over ten years.

The amount you receive depends on several factors, including the size of your system, your utility provider, and your capacity block.

The SMART program also provides higher payouts for low-income customers or those who install solar batteries.

Home Solar System Sales Tax Exemption

The Massachusetts state government also offers incentives to reduce the direct cost of purchasing solar panels. All purchases for a home solar energy system are exempted from the normal 6.25% sales tax on most products in Massachusetts. This can encourage homeowners to buy larger and more efficient solar power systems.

Solar Installation Property Tax Exemption

The Bay State grants a 100% property tax exemption on the value of the solar power system for a 20-year period. It’s important to know that this property tax exemption is only for the value of the solar power system, not the entire property.

Usually, any improvements on a home lead to a reappraisal and an increase in its value. However, in Massachusetts, any home solar power system won’t be included in the reevaluation.

How can I Sell Solar Energy in Middlesex County, Massachusetts?

There are a few ways you can sell solar energy in Middlesex County, Massachusetts. Some of them include;

Net metering

Net metering is one of the most popular ways to sell solar energy. If you’re a customer of any of the three regulated electric companies, Eversource, National Grid, and Unitil, then you can net meter in Massachusetts.

Net metering allows you to sell any excess energy that you generate from your solar energy system back to the utility grid.

What is Net Metering.jpg

At the end of each month, the utility company calculates your net consumption by subtracting the amount of electricity you used from the grid from the amount that you sent back to it.

If your net consumption is positive, then you’d pay the utility company for the difference. Conversely, if it’s negative, then you’ll receive net metering credits. These net metering credits don’t expire, and you can keep rolling them over to the next billing period.

Net Purchase and Sale

Net purchase and sale or net billing also involves selling electricity to the grid. However, under this arrangement, the prices may fluctuate.

It usually involves consumers selling electricity when there’s a high demand, and it’s expensive. This is different from net metering, where you regularly sell your electricity at a fixed rate. Net Purchase and Sale is more common with solar farms and larger companies.

Solar Renewable Energy Certificates

Massachusetts requires energy companies to source a certain percentage of the energy they produce from renewable energy to help combat climate change. These companies can either meet these requirements with their own production or buy Solar Renewable Energy Certificates to meet the quota.

As a private citizen, you receive one SREC for each megawatt hour of electricity that you produce with your solar energy system. You can sell these SRECs to companies that need them to meet their renewable energy quotas.

While this isn’t exactly selling your solar energy, it’s a great way to make some money from generating electricity using solar energy.

What are the Requirements to Sell Solar Energy in Middlesex County, Massachusetts?

Beyond your solar panel and battery, there are certain requirements you need to have before you can sell solar energy in Middlesex County, Massachusetts. Having these requirements will help you avoid hazards or legal liability. They include

Power Conditioning Equipment

Power conditioning equipment help to convert solar photovoltaic energy that’s received from the solar panels into a form that can be stored and used later. This is essential for selling solar energy, as it’s the excess that you’ve stored that you can sell.

A power conditioning system typically has an inverter, grid charger, battery, and solar charge controller.

Safety Equipment

Depending on your utility company, you may require certain safety equipment before selling solar energy to the grid. For example, some locations mandate solar systems to have a shut-off switch when the grid fails.

This is to avoid harming emergency workers who are trying to fix the grid during a blackout. Ensure you check with your energy company to confirm the specific requirements of selling energy to them.

Instrumentation and Metering

Beyond the regular electric meter, you may need special metering equipment if you’re selling solar energy back to the grid. This will help you monitor your energy consumption and how much you send to the grid. You’d also find it much easier to calculate your net metering bills and avoid disputes with your energy company.

Massachusetts has a range of laws and policies governing the installation of solar energy systems and sale of solar energy back into the grid. Ensure you check with your local government office to be sure you’re not violating any laws. It’s best to hire professionals to set up your solar energy sales system. They’re likely to be aware of legal requirements and can give you comprehensive advice on how to get started.

What Determines the Cost of Solar Panels in Middlesex County, Massachusetts?

Multiple factors determine the price of a solar energy system. Some of these include:

Size of the solar energy system

One of the major factors that influence the price of a solar energy system is its size. The more solar panels you have, the higher the cost of your collar energy system.

However, it’s important to note that while large solar power systems incur a higher upfront cost, they can help you save money on electricity in the long run. On average, most homes use 6 KW solar power systems.

Type of solar panel

Another factor that affects the cost of a solar power system is the type of solar panel it uses. Certain types of solar panels are more efficient at electricity production, making them more effective.

For example, monocrystalline solar panels are up to 5% more effective than polycrystalline and thin film solar panels. Additionally, some solar panels are more durable than others, incurring fewer maintenance costs. Thin film solar panels tend to be cheaper but less durable and will need to be changed more frequently.

Type of solar equipment

The type of solar equipment you use in your installations will also contribute to the overall cost of the solar energy system. The type of equipment you’ll require depends on your needs and specification. Massachusetts receives a sufficient amount of sunlight, making specialized solar equipment unnecessary.

However, the frequency of extreme weather conditions means Massachusetts homeowners often require a backup power supply. Installing solar batteries can add thousands of dollars to initial purchase and installation costs. Furthermore, slight variations in solar equipment can also increase costs.

Installation requirements

The ease of installing the solar energy system in your home also affects its costs. Homes with flat roofs that are easy to navigate often incur fewer installation costs.

Similarly, the installation will be cheaper if there are great locations in your building to place the solar panel so it can absorb sunlight.

Some customers opt for ground-mounted solar panels, which usually cost more. Furthermore, depending on the building’s roofing material, installing solar panels may incur additional building costs.

Solar Company

Solar companies have different installation and equipment prices. As a result, the company you pick will affect the cost of your solar energy system. Large national companies usually have cheaper equipment but may charge more for installations.

You can get quotes from different companies and decide on the one that’s best suited for you. It’s important to note that shabby installations and equipment can cause additional costs in the future. So, it’s best to find a balance between price and quality when picking a company.

Financing options

The way you decide to pay for your solar power system can also affect how much you pay for it. Paying with cash has the highest upfront cost, but the lowest overall cost. Alternative financing options like loans, leases, and power purchase agreements often have lower upfront costs, but cost more in the long run. Additionally, loans, leases, and power purchasing agreements come with the risk of the solar power system being repossessed upon default.

Additional costs

Beyond the factors above, there are additional factors that can influence the cost of a solar power system in Middlesex County, Massachusetts. Some of them include:

  • Permits: In Massachusetts, you need a building permit to install solar panels on your home or office. Usually, installation companies can handle this process, but it may come at an additional cost.
  • Licenses: Massachusetts requires anyone installing a solar panel to have the relevant licensure. The cost and difficulty of obtaining a license make labor more expensive, which can increase installation costs.
  • Warranties: Many solar companies offer warranties on their products for up to 25 years. This can help you avoid some maintenance or replacement costs.

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

The United State Department of Energy strongly recommends that you hire a licensed and certified solar installer to install your solar panels. In Massachusetts, it’s mandatory for anyone installing a solar panel to have a building permit and a license.

Additionally, while the North American Board of Certified Energy Practitioners (NABCEP) Certification is voluntary, state regulations have made it somewhat inescapable.

Do Solar Panels Increase a Home Value in Middlesex County?

Yes, solar panels increase the value of homes in Middlesex County. A study by the Lawrence Berkeley National Laboratory estimated that a solar panel installation increases a home’s value by $5,911 for each kilowatt of electricity generated.

This means that a solar system generating 4 kilowatts would increase a home’s value by $23,644. A home with a 6-kilowatt solar system would increase its value by $35,466, and so on.

Solar home value (1).jpg

The major factor that affects whether a solar system will increase a home’s value is whether its owned by the homeowner or leased.

According to the same study by the Lawrence Berkeley National Laboratory, a solar system owned by the homeowner is likely to increase the home’s value by the cost of the solar system. Contrastingly, leased solar systems don’t have any significant impact on the home’s price.

However, home buyers may incur certain costs if they intend to buy out the leased solar panel. For example, the homeowner may be behind on some lease payments. Some other factors that can affect how much a solar system increases a home’s value include:

Company policy

Some solar companies have policies that allow them to revalue a solar system if the house where it’s installed is resold. If your solar company has such a policy, it may increase the home’s value.


Electricity has different costs in each locale and state. Solar panels will be worth more in places where electricity is expensive and will add more to the home’s value.


Solar panels usually increase a home’s value by the amount it costs to purchase and install them. In places with high installation costs, homes that already have solar panels will have a higher value.

System capacity

The more power a solar system generates, the more it costs. So, homes with larger solar systems will have a greater increase in their value.

Condition of the system

Homes with old or damaged solar panels are likely to have a minimal direct increase in value. However, buyers may incur indirect costs if they decide to repair the solar system.

Are Solar Panels Exempt from Property Taxes in Middlesex County?

Yes, homes with solar panels enjoy some property tax exemptions in Middlesex County, Massachusetts.

When you install a solar power system in a home, it’s not included in its revaluation. As a result, homeowners enjoy a 100% property tax exemption on the value of the solar power system for the next 20 years.

Factors to Consider When Picking a Local Solar Company

After doing your research, you may be wondering how to pick the best solar company for you. Here are some factors you can consider to make the best choice:

Certifications and Licensing

The most important thing to consider when picking a solar company near you is if they have the required state license. Massachusetts has strict regulations for solar installations.

In addition to a building permit for installations, it must be done by a licensed professional. Additionally, some certifications can be a sign of high service quality.

For example, the North American Board of Certified Energy Practitioners (NABCEP) Certification is quite prestigious. If a local solar company has this certification, that may indicate a greater level of skill. You can ask the company if they have this certification or check their website yourself.

Check reviews online

One of the best ways to get information about a company’s services is to check its online reviews. You can find reviews on company websites and third-party resources like Yelp or Google.

Try to go through as many reviews as possible to get a balanced view of the company. Some reviews may be too positive or negative, but reading different reviews from different sources should give you an accurate description of the company’s services.

Look out for details like price, service delivery, customer service, product durability, warranties, and workmanship.

Consider your specific solar needs

One of the first things to consider is your solar needs. Not every solar company will have the panels or financing options that you’re comfortable with. After narrowing down your options, check their catalog to confirm that they have the panels you need. You can also check their websites or call their customer care to ask about their financing options.

Get multiple quotes

After researching local solar companies and narrowing them down to a few options, pick your favorite three or five. Then, contact each of them to ask for quotes. Getting quotes from multiple companies ensures you're getting competitive prices. Additionally, you can consider other factors like distance to make the best choice offers. In addition to companies you contact, you can also find quotes on online solar marketplaces. Comparing all your information can help you ensure you’re getting the best option for you in the marketplace.

Benefits of Using a Local Solar Company

There are multiple benefits that come with opting for a local solar company. Some of them include

Better prices

The National Renewable Energy Laboratory (NREL) reported that large national solar companies charged about 33 cents more per watt for solar installations when compared to local solar companies. For average users, that’s up to an additional $2,300 to install your solar panel. This difference in price may be due to the cost of traveling to the customer’s home and other factors. Regardless, opting for local solar companies can help you save a considerable amount on your local installation, making it an ideal choice.

Friendly customer service

Local solar companies serve a much smaller market than their larger national counterparts. This means that their customer service staff are less stretched out. As a result, they can dedicate more time and attention to each customer’s needs. Also, the business model of smaller solar companies usually relies heavily on customer referrals. This often leads to greater investments in the quality of customer service. Finally, local solar companies are likely to employ customer service representatives that are familiar with the locality and its quirks. This usually fosters a better connection with customers.

Quality services

Local solar companies tend to rely on full-time professional talent to serve a small market. Contrastingly, national solar companies rely on independent contractors to meet high demand. As a result, local solar companies typically offer more skilled and accountable artisans for your installations. Local artisans are also more knowledgeable about local weather conditions, solar panel prices, and custom installation options. This helps them deliver services of a higher quality.

What Solar Financing Options Are Available to Me in Middlesex County, MA?

It can cost as much as a new car to purchase and install a solar power system. This can be a huge financial commitment for most households. Fortunately, there are various financing options to help with this:


While this option isn’t very popular, customers who have enough money can pay upfront for their solar power system. This option will likely incur a higher upfront cost. However, customers will be able to take full advantage of all state and federal taxes. Additionally, customers won’t have to pay any interests that accrue under other financing options.

Solar loans

A solar loan allows buyers to borrow money from a lender or solar company to purchase and install a solar power system. Under this financing option, the buyer owns the solar power system and can take advantage of state and federal tax incentives. Solar loans are like other types of loans, involving a principal amount, interest rate, and expected payback duration. The loan may require collateral or be an unsecured loan. Usually, many buyers fix the terms of the loan such that they’re paying the same amount or lesser than their monthly electricity bill. That way, they’re still saving money while paying off the loan.

Solar Power Purchase Agreement

Under a power purchase agreement, a solar financing company is responsible for purchasing, installing, and maintaining a solar power system on the customer’s property. Then, the customer buys electricity from the company at an agreed rate per kilowatt-hour. This is usually based on a long-term contract where the customer buys electricity generated by the solar power system at a competitive rate. Under a PPA, the customer avoids all costs of purchasing, installing, and maintaining a solar power system. Furthermore, the price in the contract is binding, meaning the homeowner is protected from any increase in prices. Conversely, if electricity prices reduce, the homeowner will operate at a loss. Under this financing option, the homeowner doesn’t own the solar power system. As a result, they’re not qualified for any state or federal tax credits.

Solar lease

A solar lease is when a solar financing company purchases and installs a solar power system in a homeowner’s building, The homeowner enjoys electricity from the system and makes a scheduled payment in return. This payment may be monthly or at any other duration that the lease specifies. Under a solar lease, the homeowner avoids any purchase or installation costs. The lease specifies who handles maintenance, and it’s usually the solar financing company. Solar leases are a great way to save money if the monthly lease payments are less than the homeowner’s monthly electricity bill.
