Solar Project - Coronado Springs

Green Power Program | Business Sign-up | Residential Sign-up | Solar Demonstration Projects

Project Summary
In March 2006, the King County Housing Authority (KCHA) installed a 2.3 kilowatt solar electric demonstration project at the YWCA Career Development Center in the Coronado Springs Apartment complex. The effort included a solar installation workshop for local county, city and weatherization agency personnel, observation of onsite electrical work installing the modules, inverter, meter and associated wiring and conduit, and a tour of other Seattle Green Power solar projects. The 12 solar panels mounted on the Center's roof are visible to residents living in the nearby high-rise apartments and from the parking lot. Mount View Elementary School is nearby. Coronado Springs continues to serve as a demonstration site for agency staff, contractors and developers to see renewable energy generation in action and the simplicity of an installation.

The project was a joint effort between KCHA Housing Repair and Weatherization, Seattle City Light, Washington State Department of Community, Trade and Economic Development (CTED), Northwest Solar Center, US Department of Energy, Coronado Springs Apartments and Sound Power, Inc.

King County Housing Authority provides housing to over 17,000 families throughout King County outside the City of Seattle through Public Housing, tax credit housing and Section 8 vouchers. Installing solar electric projects is just one part of the Housing Authority's Sustainability Plan where they are developing energy efficient housing, reducing waste and hazardous materials, recycling household and electronic waste, installing water saving toilets and laundry facilities, and cutting greenhouse gas emissions.
