Program Background

Now in its seventh year, Solarize Mass is a partnership between MassCEC and the Green Communities Division of the Massachusetts Department of Energy Resources (DOER).

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 competitively 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 17,000 individuals expressing interest in pursuing solar electricity. To date, over 3,400 residents and business owners in 58 communities signed contracts resulting in 20.6 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.  Starting in 2016 the Solarize Mass program began accepting community applications on a rolling basis. In addition to the 58 communities with closed campaigns, noted above, currently there are 5 additional communities with active campaigns. See Solarize Mass Program Results (2011-2016) for information and up-to-date results. To learn more about the current Solarize Mass program, go to the Solarize Mass main page. As a part of the 2017 Solarize Mass program, MassCEC and Doer are piloting Solarize Mass Plus, a combination of the traditional Solarize Mass model, coupled with additional renewable or clean heating technology options.
