The 60,000sqft array has been built using 2,212 solar panels on the IKEA Centennial store in Denver.

The system is expected to produce approximately 740,000 kWh of electricity annually, which will help in reducing 564 tons of carbon dioxide.

IKEA Centennial store manager Kelly Frieze said the installation is in line with the company’s sustainability commitment.

"IKEA has a never-ending job where most things still remain to be done. We constantly ask ourselves how what we are doing today can be done better tomorrow. We appreciate the support of the City of Centennial, Xcel Energy and REC Solar." Frieze said.

US based IKEA is a home furnishings retailer.
