Once located in the heart of New York, Photovolt sat among some of the biggest companies in history. Located in a small office building, close to Madison Square Park and Fifth Avenue - Photovolt began what became the start of an internationally known engineering company. This prominent location was once home to well known socialites and businessmen, donning the streets of Manhatten. Some of the biggest names in retail now take up the space that was once home to many, and was the beginning of Photovolt Instruments.
