ORADELL, N.J. — Nancy and Eric Olsen could not pinpoint exactly when it happened or how. All they knew was one moment they had a pastoral view of a soccer field and the woods from their 1920s colonial-style house; the next all they could see were three solar panels.

“I hate them,” Mr. Olsen, 40, said of the row of panels attached to electrical poles across the street. “It’s just an eyesore.”

Around the corner lives Tom Trobiano, 61, a liquor salesman, now adapting to the lone solar panel hanging over his driveway. “When it’s up close,” he said, “the panel takes on a life of its own.”

Like a massive Christo project but without the advance publicity, installations have been popping up across New Jersey for about a year now, courtesy of New Jersey’s largest utility, the Public Service Electric and Gas Company. Unlike other solar projects tucked away on roofs or in industrial areas, the utility is mounting 200,000 individual panels in neighborhoods throughout its service area, covering nearly three-quarters of the state.
