New Hyde Park’s village hall could soon have a roof lined with solar panels, joining a growing list of government buildings.

Village trustee Donald Barbieri said Tuesday the board is considering his idea of installing the rooftop panels — part of a larger effort to reduce the building’s energy costs, including changing all lights to LED bulbs.

The board recently had a meeting with a company about the LED lighting, Barbieri said.

Barbieri, who has solar panels at his home, said trustees have been too busy with Long Island Rail Road third track issues to give the solar idea much thought.

“We haven’t really discussed it at length,” he said. “But there’s a potential for cost savings.”

The village hall wouldn’t be the first government building with solar panels.

The Suffolk County police precinct in Smithtown has had solar panels since 2010. The firehouse in Glen Cove went solar this spring.

The Sewanhaka Central High School District, based in Floral Park, has placed the panels on the roofs of its five high schools. Officials say the move will save $250,000 a year in energy costs.

Installing solar panels on government buildings is becoming a common practice, said Ian Weygand, president of the Long Island Solar Energy Industries Association. Many of the installations are happening at Long Island schools, he said.

Weygand said New Hyde Park could fully benefit if the entire village hall roof were filled with panels, the energy generated powered the building and any excess power were sold.

“That could cut down their overhead costs and maybe it would even be a tax break,” he said. “So if there’s any advice I could give to them it would be to do that as a community solar program.”
