Factors that Affect Solar Panel Costs in Boston

There are several factors that can play into your total installation cost, such as the size of your system, the equipment you choose, your financing options and the specific company that performs the installation.

Solar Equipment

The cost of solar panels varies by thousands of dollars due to some different factors. One of the key factors is the system size, which is measured in kilowatts (kW). Solar power systems that have greater efficiency or power production use better technology and/or more equipment, both of which can increase costs. For each additional kilowatt you need, your cost can go up by about $2,940. There are several different solar panel brands and the one you choose also affects the cost. In many cases, the brands that offer higher efficiency tend to also cost more. In addition, the type of equipment you choose can affect your total cost. If you only need panels, your system will be much less expensive than if you also need solar batteries or an electric vehicle charger.

Solar Financing Terms

Many homeowners find the average cost of solar in Boston to be prohibitively expensive, even if the investment pays off over time. Fortunately, nearly every solar company in the area offers financing options. Solar loans remarkably decrease upfront costs for most homeowners, but they also result in a higher cost over time because of interest. Though solar loans make adopting solar energy more accessible for Boston homeowners, they can also add to the total you pay for your system, depending on your interest rate and how long you take to pay off the loan. If you make a larger down payment, though, you can avoid paying as much in interest.

Solar Panel Installation Company

The last major cost factor you should take into consideration is the installer you choose. Given the booming popularity of green energy solutions in Boston, you'll have lots of options to choose from, but each comes at various price points for labor and equipment. You may see national solar installers that have lower prices because of their bigger brand name and access to bulk pricing, or you might see small, local installation companies offering deals or promotions to compete with those larger companies.

How to Save on Solar Panels

Since the brand of solar panels and the installer you choose has an impact on your costs and your system's efficiency, production, and durability, it's important to pick the right ones for you. Here are some tips to keep in mind to help with your decision:

  • Reputation: The North American Board of Certified Energy Practitioners (NABCEP) is a respected certification organization for clean energy professionals. If your solar panel installer is NABCEP-certified, it most likely has a good reputation and is qualified to do the job well. Another way you can look into your installer's reputation is by reading reviews.
  • Solar Panel Brands: Not all solar installers carry the same brands of solar panels, so the brand and type of panel you want can play a big role in the company you hire.
  • Warranty: A quality company rises above other companies by offering the gold standard warranty — a 25-year, all-inclusive warranty covering parts, labor and performance.
  • Contract: It's important to read your solar installer's contract well to understand what services they will provide, what the warranty covers and what expectations you should have about the project timeline.

EcoWatch's Boston, MA Solar Cost FAQs

What is the average cost of installing solar panels in Boston?

This is a tough question to answer exactly, because the cost depends on many factors. Generally speaking, it costs about $14,700 for a 5-kW system and $29,400 for a 10-kW system after the ITC is applied. You can expect to pay more if you want additional solar equipment or more efficient panels, or if you have higher-than-average energy usage. Conversely, you can spend less if you opt for a smaller solar panel system or less efficient solar panels.

Is it better to lease or buy solar panels in Boston?

Leasing solar panels can be an option if you can't afford to pay upfront or get a solar loan, but since you don't own the system, you don't have access to many solar incentives. Also your home value won't increase, so you'll have less savings over time. If you can afford to buy a solar system upfront, then buying is the better option if you want the most savings from going solar.

Is it worth going solar in Boston?

Solar panels can be a great investment for most homeowners, but they might not be worth it for everyone. If your home doesn't get a lot of direct sunlight and/or your electricity bills are already pretty low, solar panels might not be for you.

How many solar panels do I need to power my home?

The exact number of solar panels you need depends on your household energy needs and how much sunlight your roof gets. You can take a look at your energy bills for the past year to get an idea of the solar system size you'll need. The average household has to buy between 20 and 35 panels to account for their typical energy usage.
