The National Community Solar Partnership™ (NCSP) is a coalition of community solar stakeholders working to expand access to affordable community solar to every American household by 2025. Partners leverage peer networks and technical assistance resources to set goals and work to overcome persistent barriers to expanding community solar access to underserved communities. DOE announced the program on Wednesday, September 25, 2019.


The three goals of the partnership are:

  • Make community solar accessible to every U.S. household
  • Ensure community solar is affordable for every U.S. household
  • Enable communities to realize supplementary benefits and other value streams from community solar installations


To meet these goals, NCSP provides an array of national and local stakeholders — state, local, and tribal governments, utilities, businesses, nonprofit organizations, and others — the tools and information they need to design and implement successful community solar models. The partnership will provide these through three major activities:

  • Network Infrastructure: Partners have access to an online community platform, virtual and in-person meetings, webinars and other tools to engage with U.S. Department of Energy (DOE) staff and each other.
  • Technical Assistance: Partners have access to technical assistance resources from DOE, its National Laboratories, and independent third-party subject-matter experts for support on unique local challenges.
  • Collaboration: Structured groups of partners, called collaboratives, form around specific goals to address common barriers to solar adoption by learning from each other and sharing resources.

Upcoming Webinars

Expanding Community Solar Access and Affordability Across the United States 

February 24, 2021, 3:00-4:00 p.m. ET
This webinar will showcase innovations that are being developed by our partners and highlight progress towards our goal of expanding affordable community solar access across the United States.

Technical Assistance

To apply for future technical assistance opportunities, you must first join the partnership by registering with the community platform. Application instructions can be found on the community platform, and more details about the opportunity can be found in the technical assistance webinar slide deck.


Collaboratives are a group of similar organizations working to advance community solar in a particular market segment. Collaborative members set community solar goals, learn from their peers, and receive technical assistance over two years as they work to achieve their goals and create replicable solutions. DOE will launch new collaboratives in the future based on NCSP partner interest.

Municipal Utility Collaborative

The Municipal Utility Collaborative seeks to demonstrate replicable models for solar energy deployment that offer low or no-fee subscriptions and result in energy bill savings for low-income residents. Download the Municipal Utility Collaborative fact sheet.

Members: Austin Energ, BrightRidge, City of Colton Electric Utility, Seattle City Light, Snohomish County Public Utility District Number One, Town of Marblehead Municipal Light Department

Multifamily Affordable Housing Collaborative

The Multifamily Affordable Housing Collaborative seeks to demonstrate replicable models for solar energy deployment that reduce resident’s monthly electric utility bills by at least 10 percent. Download the Multifamily Affordable Housing Collaborative fact sheet.

Members: Boulder Housing Partners, City of Boulder, Denver Housing Authority, Fifth Avenue Committee Solar, Meriden Housing Authority, National Church Residences, New York City Housing Authority, Preservation of Affordable Housing, Seattle Housing Authority, Wesley Living

NCSP Resources


Community Solar

The U.S. Department of Energy broadly defines community solar to include any solar project or purchasing program, within a geographic area, in which the benefits flow to multiple participants (individuals, businesses, nonprofits, etc.). According to analysis by the DOE National Renewable Energy Laboratory (NREL), nearly 50% of households and businesses are unable to host rooftop solar systems. Expanding access to community solar options helps connect more Americans with clean energy for the first time. Community solar allows renters, tenants, and residents to access solar energy regardless of where they live or the suitability of their rooftop. This allows more people to offset monthly energy bills while increasing their community’s resiliency, enhancing workforce opportunities, and spurring economic development.

Expanding Access to Solar

Certain underserved markets, including low- and moderate-income (LMI) populations, nonprofit organizations, and other community-serving entities, such as municipal governments, still face significant barriers to affordable solar deployment. A report from NREL that analyzed the recently competed Solar in Your Community Challenge identified three main takeaways from the challenge:

  • Clearly understand how federal, state, and local policies enable local solar projects.
  • Build durable and long-term partnerships with community members and solar stakeholders.
  • Develop a creative portfolio of financing solutions for small- and medium-size solar projects.

NCSP builds on the successes of the Solar in Your Community Challenge to support the replication of new and existing community solar models by partnering with diverse stakeholders across the country that are interested in expanding affordable access to solar.
