In July 2012, the DEP installed a 184 kilowatt (kW) Solar Photovoltaic (PV) array on the roof of its Headquarters at 401 East State Street in Trenton, New Jersey.  The Solar PV array consists of 784 panels that are each 235 watts, and is net metered, allowing the electricity produced to directly power the DEP building. On average this Solar PV array produces over 230,000 kW/hours annually. This enough to power about 32 homes for a full year! DEP’s Solar PV array is one of a handful of Solar PV systems at New Jersey State owned facilities.

The performance of the DEP Solar PV array is tracked through the Noveda Technologies Sunflow Monitor. The monitor, located in the lobby of the DEP headquarters, is interactive and displays live system performance, equivalent homes powered, and avoided greenhouse gas emissions for the day, month and year.
