Community Solar

Community Solar is a collective or sharing model for going solar. In Community Solar, a group of participants put up the money to build a larger solar array and then share the benefits among themselves as well as with the place where the solar is sited.

Recent Washington Community Solar news & updates 

August 2022: Thurgood Marshall MS to get solar panels in new partnership

The Olympia School District is partnering with Olympia Community Solar to build a new Community Solar installation on the Thurgood Marshall Middle School roof.  The Thurgood Marshall Community Solar Project is planned to begin construction in summer 2023 and will offset the power usage of the school with renewable energy. The project will include 306 solar panels across the school roof. Puget Sound Solar will design and install the 150 kw system that will be capable of producing 149 thousand kilowatt-hours a year. This will reduce the school’s energy bill, contribute to sustainable infrastructure in Olympia, and create student learning opportunities about renewable energy.

Thurgood Marshall will become the fifth Olympia School District school to have solar panels. There are currently solar panels at Olympia High School, Olympia Regional Learning Academy, Roosevelt Elementary and Washington Middle School.

Ownership of the project is publicly available. Community members provide the upfront project capital by purchasing or donating solar units to the project’s energy production. Over time participants recover their contribution through the sale of electricity. More details about the project and about participation are available on the Olympia Community Solar website.

July 2020: New Department of Commerce funding to focus on low-income community solar

Previously, $1,522,000 in state funding was awarded to three projects deploying solar technologies across the state. New program guidelines are currently under development to align with revisions made under the 2019 capital budget SHB1102 to the requirements of the Solar Deployment Program. The new solicitation is expected to focus on low-income community solar deployment, and to cover at least $2,328,000 in remaining funds. Click for details

April 2020: Legislative Session

During the 2020 Washington State Legislative session, HB 2248 was introduced to expand equitable access to the benefits of renewable energy through community solar projects. Link to bill. Both the Washington House and Senate signed off on the bill and was subsequently delivered to Governor Inslee on March 12, 2020 for his signature, Gov. Inslee later vetoed funding for the bill due to COVID-19 related budget cuts. View veto message from Governor Inslee. Link.

About Community Solar in Washington

In Washington State, Community Solar makes solar accessible to are people who don’t own their own home, don’t have a sunny location, cannot afford the upfront cost of solar or simply want solar at a lower entry price.

Under Washington’s solar incentive program enacted in July 2017, a Community Solar program participants may receive incentive payments via an Administrator under a program governed by RCW 82.16.165. RCW 82.16.170 defines Community Solar program types and outlines the responsibilities of the Community Solar Project Administrator. However, it is important to note that Community Solar Projects may be structured completely differently outside of the State RESIP Program.

  • Program must be pre-certified by WSU extension energy program.
  • Maximum payment per participant is $5000 year.
  • Program parameters are described in the chart below and in RCW 82.16.165.
  • System size must be under 1000 KW.
  • Project must have at least 10 participants or one participant for every 10 KW of capacity, whichever is greater.
  • A Community Solar Project may be organized by a Washington electric utility or by a private entity.

In early 2019, Spark Northwest released a report entitled Community Solar in Washington State History and Path Forward that explains and analyzes past Community Solar state policies, including a focus on inequity, and makes suggestions for the future policies. The report describes models that have worked well in other states.

Another model for taking collective action is called Solarize (a program of Spark Northwest). In this model, a group of home-owners each buy their own solar systems but they come together to go solar as a neighborhood and get a group-buy discount. Together they select one installer and set the time schedule. Learn about the current Solarize Campaigns.

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. This partnership will develop multi-stakeholder teams to convene around specific goals, provide technical assistance for unique local challenges, and develop an online community platform to support information exchange. The program was announced on Wednesday, September 25, 2019. Click for more information
