About Us

Who We Are

A rapidly growing company of energy solutions specialists

Founded in 2011, Boston Solar began with its name: delivering solar to the Boston area. It wasn’t long however before the company’s offerings expanded beyond solar. Weatherization services and high efficiency heating & cooling systems joined solar to provide a complete energy solution for customers. In addition to broadening its products, Boston Solar soon grew beyond Boston with a new office opening in North Haven Connecticut and sales extending into New Hampshire.


After 1800+ solar installations, the company has become recognized as a major solar provider in New England. Last year Solar Power World named Boston Solar the number one residential solar installer based in Massachusetts. With over 130 employees, the company does more home installs of solar systems than any another headquartered in the Bay State.  


Along with solar, Boston Solar has done over 750 home weatherizations plus over 300+ installs of heating & cooling systems. The trio of services makes the company a unique total energy solutions provider. No one else has its own expertise in these three areas which usually get sub-contracted out. Boston Solar can address all the energy needs of a home or business using its in-house team of engineers and technicians. This allows for complete integration of energy services, providing customers with an optimal and convenient solution under one roof.


The latest advances in technology have enabled clean, efficient solutions to power people’s lives. Boston Solar puts control of energy in the hands of its customers

Boston Solar About Us
Save Energy

Why We Do It

Save energy, save money, save the world

We live in a world of growing energy needs. Technology multiplies, people multiply, and energy consumption multiples in turn. But while energy powers things that benefit our lives, energy afflicts them as well, from our bank accounts to the planet. Increasing utility bills strain the cost of living with a larger financial burden, while fossil fuels harm the environment with their destructive extraction and polluting consumption. We can’t afford either of these consequences.


We believe the solution is a more intelligent approach to energy that saves more and harms less. Instead of paying for energy from a dirty power plant, we can generate clean, free energy with solar panels. Instead of losing energy in a leaky home, we can seal and insulate it against loss. And instead of wasting energy on inefficient heating & cooling systems, we can consume less while getting more comfort.


If we can improve how energy is used in one home, we will help one person save. If we can improve how energy is used in everyone’s home, we will help the world save--and help save the world!


Equipment Partners

In the energy business, efficiency matters. To get that optimal performance requires using quality equipment from reputable manufacturers. That’s why we carefully choose our suppliers to give you the best technology in the industry. Here is who we work with.
