The DAR Goes Solar


Standard Solar announces it’s completed a solar installation on the historic DAR Constitution Hall in Washington, DC. The array is expected to produce 100,786 kWh of energy per year and will help offset the energy demand of the concert hall.

It’s not always easy for a historic home or other building to go solar, but it can be done. 

The historic DAR Constitution Hall is proof of that. Located in Washington, DC just off the National Mall and a few hundred yards from the White House, the Hall opened in 1929 to house the annual Daughters of the American Revolution (DAR) convention. It’s now Washington DC’s largest concert hall, welcoming more than half a million patrons each year. It was designated a National Historic Landmark Building in 1985.


It took extra care to design a solar system on this historic landmark, and solar provider Standard Solar was up to the job. The company worked closely with DAR on the innovative installation to ensure it met structural conditions and historic preservation requirements, as well as making economic sense. Standard Solar announced this week that it has completed the solar installation.


The array, mounted on the rooftop of the Hall, is expected to produce 100,786 kWh of energy per year and will help offset the energy demand of DAR Constitution Hall.


“This project with DAR is a leading example of how solar production can be maximized even on urban buildings where space is limited,” said Tony Clifford, CEO of Standard Solar. “In addition to being innovative with the use of rooftop space, our design had to integrate the requirements of a historic building and maintain the integrity of the architecture. The result is a highly efficient advanced solar system powering an 85 year old historic structure — a progressive blend of history and modern technology.”


“A Conservation Committee dedicated to all things environmental has existed within DAR for over 105 years, and historic preservation is one of our Society’s founding missions,” stated DAR President General Lynn Forney Young. “So when presented the opportunity to reduce operating costs in a manner that conserves energy and preserves the historic fabric of our National Headquarters at the same time, it was an easy decision to make. Next year will be DAR’s 125th anniversary, and I am proud that our organization continues to change with the times and embrace innovative technology that is good for DAR, the Washington, D.C. community and the environment.”


Standard Solar used PV solutions from tenKsolar, a commercial rooftop solar solutions provider, enabling the team to maximize the array output, minimize weight loads, and deliver savings to DAR.


“tenK has dedicated years of engineering into delivering the best all-around system for flat rooftops. This project showcases why tenK is a leading choice for maximizing rooftop solar sites with weight and space limitations,” said Joel Cannon, CEO, tenKsolar.
