Staples, SunEdison unveil largest single rooftop solar-power installation in Md.

Hanover, Md. Staples has unveiled the largest single rooftop solar-power installation in Maryland at Staples' 200,200-sq.-ft. fulfillment center in Hanover. The 1.01 megawatt solar installation covers nearly 175,000 sq. ft. of roof space, larger than three football fields.

The zero-emission, silent photovoltaic system will generate approximately 1.2 million kilowatt-hours (kWh) of electricity per year, and 21 million kWh during the initial 20 years of the project. The solar installation was financed, built and maintained under a power purchase agreement with SunEdison. Under the PPA, Staples will purchase the electricity produced for the term of the contract.

"The solar-power system installed at our Hanover fulfillment center is the latest example of Staples' ongoing commitment to environmental leadership," said Mark Buckley, VP environmental affairs for Staples. "Through our relationship with solar services provider SunEdison, we are able to purchase solar energy from our rooftop at a rate below or equal to the cost of electricity from the grid. This reduces our operating costs while freeing up more electricity during peak times for use by local homes and businesses."
