The best way to pick a reputable solar company in Massachusetts that ticks all of the boxes for your installation is to have the right questions on hand and research the company to ensure it’s a good one. Here are a few questions to help you get started:

• What types of solar panels do you carry?

• Does your company offer monitoring services for solar panels?
• Do you do roof repairs or installations?
• What kinds of warranties do you have?
• On average, how much does a solar system cost with your company?
• What kind of financing plans for solar do you offer?
• What does the installation process look like?
• Do you do everything in-house, or do you outsource installations or other services to third-party companies?
• Do your solar panels have the best snow and wind resistance to handle Massachusetts winters?

Ensure you ask these questions to multiple Massachusetts solar companies to compare responses and choose the company that best reflects the qualities you want from an installer. You also want to make sure that the customer reviews are positive and the referrals support high-quality installation services to avoid biased responses from the company.

The average 6.5 kW solar system costs in Massachusetts is around $18,600, but prices can range from $16,600 to $20,500. Solar costs will vary by company, and you can expect to spend more on high-quality solar panels than you would on low-quality panels, among other factors.

Solar Panel Cost Factors

A slew of variables can alter the cost of your solar panels, making it a little challenging to know exactly how much you’ll spend before speaking with an expert and receiving a quote. Still, these are the most common cost factors that will have the biggest impact on how much you spend:

• Brand/Quality. Solar panels can be broken down by tier level, with Tier-1 panels being the most advanced and costly, and Tier-3 panels being the cheapest but potentially less efficient. You’ll want to find a balance between cost-effective and efficient panels to get the best return on investment. Look for a solar company in Massachusetts that is committed to getting you there.
• Size. Since solar systems cost between $2.55 and $3.15 per watt on average, the size of your system will greatly impact the final price tag. By investing in a smaller system and lowering your energy consumption, you can save on energy and solar panel expenses.
• Labor. The company installing your solar panels will set its own rates depending on competition and other behind-the-scenes factors, making it important to compare quotes from several Massachusetts solar installers.

Massachusetts has one of the most ambitious solar initiatives in the US, with plenty of helpful incentives to help you switch to renewable energy, including:

• Federal solar tax credit: Expiring at the end of 2025, the federal solar tax credit is a tax credit equal to 30% of the total cost of qualifying solar systems nationwide.
• Residential Energy Credit: Massachusetts has an energy credit of up to 15% of the total cost of a solar system for up to $1,000 that is applied to your personal income tax.
• Massachusetts solar property tax exemption: With this policy, even if your solar system increases your assessed value, you won’t have to spend more on your property tax. There are specific qualification requirements, so be sure to check that your system will qualify before counting on it. This exemption lasts for 20 years.
• State sales tax exemption: You won’t pay the state sales tax of 6.25% on a solar system with this exemption, saving you around $1,150 on average.
• Net metering: Massachusetts has net metering that allows you to receive credits on your electric bill for excess energy produced by your solar panels that is sent to the grid. Again, be sure to check the requirements to ensure that your system will qualify.
• Solar Massachusetts Renewable Target (SMART) program: This program is an incentive-based one that helps eligible residents and businesses develop solar systems in the state.
• Solar for All program: Not currently active, applicable low-income Massachusetts residents will be eligible to receive a 20% savings on their electric bills and financing assistance for solar installations.
