High resolution solar resource maps of New Brunswick were developed to choose the best areas for locating a pilot utility-scale PV plant and testing facility. Green Power Labs’ solar resource and GIS expertise were utilized to develop a comprehensive data set of the solar resource from satellite sources and ground-based weather stations. The map set included monthly and annual average of global horizontal, direct normal and diffuse irradiation maps for New Brunswick with a resolution of 1 sq. km. Five 50 x 50 km areas of interest were presented in detail to quantify and describe significant variations in the solar resource potential related to topographic and coastal effects, and to assist in identifying potential project sites.
