Low-Income Services Solar Program (LISSP)
On-site solar for nonprofits and community service organizations
The Low-Income Services Solar Program is a Massachusetts program that helps nonprofit and community service organizations install on-site solar photovoltaic (PV) systems on their buildings.
About the program
While the name Low-Income Services Solar Program (LISSP) references “low-income services,” it is not a community solar program and does not involve residential subscriptions. Instead, LISSP focuses on bringing solar directly to the facilities of organizations that provide critical services. While many participating organizations serve low-income and environmental justice communities, projects may also support broader populations, as long as the services provided meet program eligibility criteria.
The program is funded by the Massachusetts Department of Energy Resources (DOER) through its Powering Community Services with Solar initiative and is administered by CET, which provides technical assistance to participating organizations.
