The Daughters of the American Revolution (DAR) Constitution Hall photovoltaic system helps the DAR to stabilize and reduce electric energy costs for its complex of historic buildings in Washington, D. C., just a few hundred yards from the White House. The rooftop 59kW solar panel array installation was completed in June 2014 and produces about 100,786 kWh of energy per year to help offset the energy demand of DAR Headquarters. Designed to house the annual DAR convention, Constitution Hall (as of August 2015) was designated a National Historic Landmark Building in 1985 and is Washington D.C.’s largest Concert Hall, with more than half a million patrons each year. DAR has had a conservation committee dedicated to environmental issues for more than 105 years.
