Massachusetts ranks #3 in America for savings from installing solar panels on your home

Solar power in Massachusetts

Last fact checked on January 23, 2020 by Catherine Lane

Although Massachusetts has fewer daily sun hours compared to other parts of the country, the state’s high utility power costs make solar a great investment for the home.

Massachusetts offers numerous incentives for going solar, including the residential renewable energy income tax credit which provides up to $1,000 of credit towards your state income tax. This, coupled with the federal tax credit, makes going solar a viable option for Massachusetts homeowners.

As part of the state’s Renewable Portfolio Standard (RPS), Massachusetts set a specific goal for electricity generation from solar panels, otherwise known as a solar carve out, in 2008. The solar carve out served as support for a solar renewable energy credit (SREC) market.

In late 2018, applications for the SREC program ceased and a new program, the Solar Massachusetts Renewable Target (SMART) Program, began. The SMART program no longer uses SRECs to incentivize solar. Instead, homeowners are offered a fixed rate for each kWh of power their system provides to the grid for 10 years.

You can install high-quality solar power systems from reputable installers as low as $2.82 per watt before incentives. With these prices, the payback period could be as little as 5 years or less and have an internal rate of return on investment of over 20%.

What are the pros and cons of buying solar panels for your home in Massachusetts

Some of the advantages of installing solar panels in Massachusetts include state incentives, the federal tax credit, and the expensive power rates. Higher power rates mean the overall return on investment for an installation of residential solar panels in Massachusetts is the best in the nation.

SolarPowerRocks provides a great breakdown of solar incentives and policy for each state within the US.

What's the downside of installing solar panels in Massachusetts? There is a lower level of emitted solar irradiance. As a result, solar systems in the state produce less energy than they could if stationed in other areas. However, the local incentives more than make up for this.

If you’re a Massachusetts homeowner, you’ll be kicking yourself that you didn’t install solar panels while these generous incentives were still around.

Best brands of solar panels

To find the best brands of solar panels you can use America's most trusted solar panel comparison and reviews website, SolarReviews.

However, reviews of solar panels can be a bit meaningless because most consumer owners have not had any issues and so while solar company reviews are very important when choosing solar installers they are of less use when choosing solar panels.

For more information to help you make an informed decision about this topic, I would recommend this article about buying solar panels.

How much electricity will solar panels produce in Massachusetts

Solar panels produce different amounts of energy in different locations.

Around the Boston area solar panels installed on a south facing 27 degree pitch roof will typically produce:

1,150kWh per year per 1kw of peak DC (direct current) capacity

For more information about how your location, roof direction and roof tilt affects solar power production use the solar panels calculator and enter your zipcode below.

What rebates, solar tax credits and other solar incentives are available in Massachusetts?

Massachusetts State Solar Tax Credit

Massachusetts has an excellent tax credit incentive that can be used in addition to the 26% federal solar tax credit.

The Massachusetts state solar tax credit provides a credit equal to 15% of the total cost of a renewable energy system installed on your primary residence. However, the credit may not exceed $1,000.



Tax exemptions

Massachusetts offers two tax exemptions for solar systems: a sales tax exemption and a property tax exemption.

Under the renewable energy equipment sales tax exemption, equipment related to any solar system for the purpose of supplying energy is not subject to state sales tax.

The renewable energy property tax exemption exempts the assessed value of a solar system from a homeowner’s property tax for a 20-year period.



The SMART Program and Massachusetts RPS

Massachusetts has a renewable energy target that has mandated utilities operating in the state to obtain a certain percentage of their electricity from renewable sources.

By December 31, 2019, utilities must derive 14% of their sales from renewable energy sources. For each following year, the required percent derived from renewable energy will increase by 1%.

In late 2018, the state’s popular SREC program was replaced with the SMART program. Under SMART, your utility pays a flat base rate per kWh of energy that is sent to the grid from your solar system for 10 years. The base rate you qualify for is dependent on your utility and when you apply to the program. The sooner you apply, the higher the base rate you receive.

You can also qualify for different “adders”, which is additional money you can earn per kWh if your system meets certain requirements. For example, if a system is built on a brownfield, the system owner can earn an additional $0.03 per kWh on top of their base rate.  



Mass Solar Loan Program available to Massachusetts residents

In January 2015, the Massachusetts Department of Energy Resources (DOER) and the Massachusetts Clean Energy Center (MassCEC) launched the Mass Solar Loan Program, a $30 million residential loan program to make it easier for homeowners to finance solar projects. The program provides low-interest loans for the purchase and installation of solar systems.

Is a purchase, lease, or power purchase agreement (PPA) best?

Solar leases and solar PPAs are popular financing options that are ideal for many homeowners who are considering solar. They make the installation of a solar system possible, without the upfront costs associated with installation and maintenance.

However, generally speaking, you will see far greater savings over the life of a system if you purchase your solar panels outright rather than enter into a third party-owned solar lease or solar PPA. You also will not be able to redeem the 26% federal tax credit.

You can use the solar savings calculator to see the difference in the overall savings over the life of a system.
