The system, comprising 16,500 photovoltaic panels, is located on land adjacent to Princeton’s main campus in West Windsor. The collector field is connected to the Princeton main campus electric power distribution system and provides about 5.5% of Princeton’s annual electrical needs.
During the first 8 years of the collector’s operation, Princeton leased the installation from a company that sold its environmental benefits through New Jersey’s Solar Renewable Energy Certificate (SREC) program. When that arrangement ended, Princeton stoped selling SREC’s and claimed the environmental benefits. This project contributes nearly 6 percent of the carbon emissions reduction goal set by the University’s Sustainability Plan. (That plan called for the University to reduce its greenhouse gas emissions to 1990 levels by 2020. The current plan calls for Princeton to achieve carbon nutrality for campus operations by 2046.)
