How does the solar co-op work?

Co-op members learn about of solar so they feel confident in their decision to go solar. They also have the technical expertise and support of non-profit DC SUN as they go solar. DC SUN has helped hundreds of homeowners go solar.

By going solar together as a group, the co-op gets a discount through its bulk purchasing power, saving an average of 20% compared to the cost of an individual installation. The co-op solicits competitive bids from local installers in order to get the most competitive pricing. Co-op members each get an individualized proposal for their home that reflects the group discount.

The group will complete the following process to ensure a smooth and organized experience for everyone involved:

How much will going solar with the co-op cost?

The cost depends on whether you purchase your solar panels yourself of go solar with a Power Purchase Agreement (PPA). Under a PPA, a third party (usually the installer) owns the system installed on your roof. You purchase the electricity produced by the system, but the rate you pay for that electricity is generally lower than what you pay Pepco. With a PPA, you can go solar for $0 upfront, and just pay for the electricity that the panels produce.

If you purchase a system, below are estimates for the costs and incentives available for two solar installations — a small 3 kilowatt system and a large 9 kilowatt system. Your purchase cost will almost certainly fall between these two examples, depending on how big your roof is and what you’re able to afford.

DC SUN is a nonprofit project of Community Power Network (CPN), a network of grass roots, local, state, and national organizations working to build and promote locally based renewable energy projects and policies. CPN’s founder and executive director, Anya Schoolman, formed the group after she tried to install solar on her Mt. Pleasant home in 2007 and saw how challenging the process was at the time. She organized her neighbors to help make the process easier and more affordable and has been helping others through the process nationwide ever since. CPN provides DC SUN with support and access to a national network of solar homeowners, practitioners, partners, policy experts, and policy makers.
