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.

In Washington State, there are two types of Community Solar that are allowed to collect incentives. The maximum incentive rate under the 2005 Incentive Legislation is $1.08/kwh for Made-in-WA systems.

The two models in Washington are:

  1. Utility Sponsored – Usually the utility determines the site of the installation and manages the program. Customers of that utility can buy a share for set price that is usually between $500 to $1500. These customers are then allowed to take the 30% federal tax credit on the price of their share. In addition, they receive on bill credits for their portion of the total solar energy produced by the system each billing cycle (virtual net metering) as well as an annual payment from the Washington State Production Incentive. The solar system reamins an asset of the utility.
  2. LLC Sponsored (For-profit or Non-profit Sponsored) – In this model, the location for the solar system must be a public entity (public school, fire station, library, city hall). Either an LLC or a Nonprofit Entity sponsors the solar project and sells the share. They also collect the WA Production Incentive for the whole system. Participants buy a share and like above are able to take a 30% federal tax credit on the price of the share. They also earn a percentage of the WA Production Incentive equivalent to the percentage of the system that they own, but it is paid to the nonprofit or company, and then the nonprofit or company pays the investors. Different entities set things up differently, but the intent is that, at the end, the customer earns back all their upfront cost AND the public entity gets the benefit of the solar power to reduce their electric bill in the years beyond the end of the incentive period.

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.

Examples of Community Solar Projects

A different 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.

    Dear Diane,
    WA State Parks renovated the restroom at Camano Island State Park and put solar on top. The solar helps to offset grid power needed to pump waste a long distant and uphill drainfield, so an unusual situation. It’s also a well-used larger “comfort” station. There might be a public record of what the whole restroom cost.

    The Rosalia Visitor Center for the Steptoe Battlefield and community (which is a restored 1923 Texaco Station and is on the National and State List of Historic Places, was completed in 2006. Since that time funds have not been available to continued with Phase 3 which is installing a 24/7 public restroom (which is required before the Dept of Transportation will place a directional sign on nearby SR195. Plans are underway and funding maybe possible but we need to contact a contractor in the Spokane area that will give us an idea of what a solar powered 24/7 unit and will cost ? Any help will be appreciated.
