Powering Historic Buildings: Solar Panel Projects Around the Country

As covered in the Summer 2013 issue of Preservation magazine, it would be hard to come up with a more high-profile and historically significant place to install solar panels than Alcatraz Island in the San Francisco Bay. But as the price of solar panels and equipment continues to fall and people generally get more comfortable with this source of clean energy, it no longer requires a large chunk of federal dollars (which was the case with Alcatraz) and years of effort for historic buildings to tap the sun to meet their electricity needs.

For instance, this past winter and spring the Mystic Seaport in Connecticut installed a 230-kilowatt solar power plant -- just under 1,000 panels -- on the roof of an old mill building that houses the museum’s collections and some administrative offices. As is so often the case, the impetus to cover 43,000 square feet of the 1800s-era building with solar panels was both environmental and economic.

“It will generate 10 percent of the power the mill uses,” says Ken Wilson, the director of facilities at the Seaport, who notes that the electricity produced will be cheaper than what would otherwise be available from the utility. “And it’s an attempt to move in a more green direction.”

At the Seaport, Wilson says the museum worked closely with the town of Stonington to address any historic preservation concerns. The main issue was whether or not the panels could be seen. In this case, it was not a problem because the building still had an original brick parapet shielding the panels from view.

Elsewhere around the country, solar panels are helping provide electricity to both historic residences and commercial buildings. In Richmond, California, a former Ford Motor Company Assembly Plant that churned out Model A cars in the 1930s is not only covered with solar panels, it has also become a facility for SunPower Corporation, one of the leading makers of panels. In Bethesda, Maryland, a local landmark known as the Sycamore Store added solar panels in such a way that they are actually visible from the street.

Clearly, individual circumstances and concerns about the impact of transforming an historic building into a solar power plant are highly specific -- sometimes it’s appropriate, and sometimes it’s not. But the sort of give and take that goes into these decisions is hardly foreign to the companies that install solar panels, accustomed as they are to customers who voice their opinion about a project’s visual impact.

“We in the solar industry are well-prepared to deal with these things,” says Gary Gerber, president of California-based Sun Light & Power. “We have run into these situations enough that it’s not far out of our wheelhouse.”

    Very nice article, pointing out some of the decisions to be made about historic preservation as well as forward, sustainable measures. In 2010 we installed a ballasted 43kW solar array on the roof of the Bourse Building in Philadelphia. Opened in 1895 as America’s first commodities exchange, the Bourse is across the street from Independence Hall on 5th Street, and currently serves as a multi-use office building, with a public food court and mall on the ground floor.

    You can see solar panels on the back of Ypsilanti’s Historic City Hall here.

    From the Huffington Post June 21 2011:
    [b]Obama Administration Fails On Promise To Put Solar Panels On White House Roof By June 21[/b]
    “The White House will lead by example,” United States Secretary of Energy Steven Chu said during remarks at the GreenGov Symposium on Oct. 5, 2010. “I’m pleased to announce that by the end of this spring, there will be solar panels that convert sunlight to energy and a solar hot water heater on the roof of the White House.”

    It has been more than two years since this promise was made. Any updates?
