IT’LL TAKE A LITTLE WHILE TO ASSEMBLE THAT NEW IKEA ROOFTOP FURNITURE All the pieces are there, but now here comes the hard part. A scene familiar to many IKEA customers is now taking place on a large scale on top of the Houston IKEA store’s roof, where workers from contractor REC Solar are assembling flat-packed stacks of 3,962 solar panels into a 116,400-sq.-ft. PV array. The panels arrived on site at the end of last year, but construction won’t be complete until sometime this summer. When it’s done, the company says, the installation will generate enough energy to power 113 homes — or a larger number of in-store room displays.
