IKEA, a Swedish furniture company building massive stores throughout the United States, flipped the switch on yet another rooftop solar array this week.

The Atlanta store officially plugged its 129,400-square-foot solar system into the grid Monday.

The array will produce about a fourth of the energy the 366,000-square-foot store will use, said IKEA spokeswoman Deidra Cunningham.

The array is made up of 4,312 solar photovoltaic panels and will produce about 1.4 million kilowatt hours of clean electricity a year. That’s enough to power 122 average Atlanta homes.

The Georgia solar installation marks the 23 IKEA store in the country to go solar.

“We’re still working on the other 16,” Cunningham said.

The furniture company has made a commitment to sustainability and aims to install solar panels on the rooftops of all its superstores.

It completed another installation in Pennsylvania just last week.

IKEA owns and operates all of its own solar installations rather than leasing the panels or entering into a power purchase agreement, according to a press release from the company.

Once the remaining 16 stores have their solar arrays installed, 89 percent of the company’s US stores will be solar powered and together they will represent 38 megawatts of solar power generation capacity.

“We’re really excited about this,” Cunningham said. “It helps to further our energy efficiency goals and reduce our carbon footprint.”

She said community leaders and new media will have a chance to tour the solar array and see its inner workings Tuesday.

IKEA, coming from Sweden, has a commitment to the natural environment and a deep-seeded interest in sustainable business practices, Cunningham said.

The company thinks through everything from how it packages its furniture to how it lights and powers its buildings with sustainability in mind, she said.
