Program Background

Now in its sixth year, Solarize Mass, a partnership between MassCEC and the Green Communities Division of the Massachusetts Department of Energy Resources (DOER), has led to more than 2,700 residents and business owners in 51 cities and towns across the Commonwealth signing contracts for small-scale solar electricity systems.

How it works

The Solarize Mass program looks to increase the adoption of small-scale solar electricity systems through a grassroots educational campaign, driven mainly by local volunteers and reduced pricing that increases the savings for participants. 

Each participating community comptitively selects a designated solar installation company. Homeowners and business owners who want to participate can either purchase the solar electricity systems directly or enter into a lease or power purchase agreement (PPA) with the installer if offered. Under a lease or PPA, the installer will own, operate and maintain the system, while the home or business owner agrees to purchase the power generated by the system as a specific rate. 

Since Solarize Mass launched in 2011, the program has resulted in more than 15,000 individuals expressing interest in pursuing solar electricity. Over 2,700 residents and business owners in the 51 communities signed contracts resulting in 17 megawatts of contracted capacity. In addition, the number of small-scale solar electricity projects in almost every community doubled as a result of the program. For a full list of communities who have participated in the Solarize Mass program and additional program analysis, please see program results below.
